Rationale for Research

What is the Rationale of Research?

The term rationale of research means the reason for performing the research study in question. In writing your rational you should able to convey why there was a need for your study to be carried out. It’s an important part of your research paper that should explain how your research was novel and explain why it was significant; this helps the reader understand why your research question needed to be addressed in your research paper, term paper or other research report.

The rationale for research is also sometimes referred to as the justification for the study. When writing your rational, first begin by introducing and explaining what other researchers have published on within your research field.

Having explained the work of previous literature and prior research, include discussion about where the gaps in knowledge are in your field. Use these to define potential research questions that need answering and explain the importance of addressing these unanswered questions.

The rationale conveys to the reader of your publication exactly why your research topic was needed and why it was significant . Having defined your research rationale, you would then go on to define your hypothesis and your research objectives.

Final Comments

Defining the rationale research, is a key part of the research process and academic writing in any research project. You use this in your research paper to firstly explain the research problem within your dissertation topic. This gives you the research justification you need to define your research question and what the expected outcomes may be.

How to Write the Rationale for a Research Paper

  • Research Process
  • Peer Review

A research rationale answers the big SO WHAT? that every adviser, peer reviewer, and editor has in mind when they critique your work. A compelling research rationale increases the chances of your paper being published or your grant proposal being funded. In this article, we look at the purpose of a research rationale, its components and key characteristics, and how to create an effective research rationale.

a researcher writing the rationale for a research paper

The rationale for your research is the reason why you decided to conduct the study in the first place. The motivation for asking the question. The knowledge gap. This is often the most significant part of your publication. It justifies the study's purpose, novelty, and significance for science or society. It's a critical part of standard research articles as well as funding proposals.

Essentially, the research rationale answers the big SO WHAT? that every (good) adviser, peer reviewer, and editor has in mind when they critique your work.

A compelling research rationale increases the chances of your paper being published or your grant proposal being funded. In this article, we look at:

  • the purpose of a research rationale
  • its components and key characteristics
  • how to create an effective research rationale

What is a research rationale?

Think of a research rationale as a set of reasons that explain why a study is necessary and important based on its background. It's also known as the justification of the study, rationale, or thesis statement.

Essentially, you want to convince your reader that you're not reciting what other people have already said and that your opinion hasn't appeared out of thin air. You've done the background reading and identified a knowledge gap that this rationale now explains.

A research rationale is usually written toward the end of the introduction. You'll see this section clearly in high-impact-factor international journals like Nature and Science. At the end of the introduction there's always a phrase that begins with something like, "here we show..." or "in this paper we show..." This text is part of a logical sequence of information, typically (but not necessarily) provided in this order:

the order of the introduction to a research paper

Here's an example from a study by Cataldo et al. (2021) on the impact of social media on teenagers' lives.

an example of an introduction to a research paper

Note how the research background, gap, rationale, and objectives logically blend into each other.

The authors chose to put the research aims before the rationale. This is not a problem though. They still achieve a logical sequence. This helps the reader follow their thinking and convinces them about their research's foundation.

Elements of a research rationale

We saw that the research rationale follows logically from the research background and literature review/observation and leads into your study's aims and objectives.

This might sound somewhat abstract. A helpful way to formulate a research rationale is to answer the question, “Why is this study necessary and important?”

Generally, that something has never been done before should not be your only motivation. Use it only If you can give the reader valid evidence why we should learn more about this specific phenomenon.

A well-written introduction covers three key elements:

  • What's the background to the research?
  • What has been done before (information relevant to this particular study, but NOT a literature review)?
  • Research rationale

Now, let's see how you might answer the question.

1. This study complements scientific knowledge and understanding

Discuss the shortcomings of previous studies and explain how'll correct them. Your short review can identify:

  • Methodological limitations . The methodology (research design, research approach or sampling) employed in previous works is somewhat flawed.

Example : Here , the authors claim that previous studies have failed to explore the role of apathy “as a predictor of functional decline in healthy older adults” (Burhan et al., 2021). At the same time, we know a lot about other age-related neuropsychiatric disorders, like depression.

Their study is necessary, then, “to increase our understanding of the cognitive, clinical, and neural correlates of apathy and deconstruct its underlying mechanisms.” (Burhan et al., 2021).

  • Contextual limitations . External factors have changed and this has minimized or removed the relevance of previous research.

Example : You want to do an empirical study to evaluate the effects of the COVID-19 pandemic on the number of tourists visiting Sicily. Previous studies might have measured tourism determinants in Sicily, but they preceded COVID-19.

  • Conceptual limitations . Previous studies are too bound to a specific ideology or a theoretical framework.

Example : The work of English novelist E. M. Forster has been extensively researched for its social, political, and aesthetic dimensions. After the 1990s, younger scholars wanted to read his novels as an example of gay fiction. They justified the need to do so based on previous studies' reliance on homophobic ideology.

This kind of rationale is most common in basic/theoretical research.

2. This study can help solve a specific problem

Here, you base your rationale on a process that has a problem or is not satisfactory.

For example, patients complain about low-quality hospital care on weekends (staff shortages, inadequate attention, etc.). No one has looked into this (there is a lack of data). So, you explore if the reported problems are true and what can be done to address them. This is a knowledge gap.

Or you set out to explore a specific practice. You might want to study the pros and cons of several entry strategies into the Japanese food market.

It's vital to explain the problem in detail and stress the practical benefits of its solution. In the first example, the practical implications are recommendations to improve healthcare provision.

In the second example, the impact of your research is to inform the decision-making of businesses wanting to enter the Japanese food market.

This kind of rationale is more common in applied/practical research.

3. You're the best person to conduct this study

It's a bonus if you can show that you're uniquely positioned to deliver this study, especially if you're writing a funding proposal .

For an anthropologist wanting to explore gender norms in Ethiopia, this could be that they speak Amharic (Ethiopia's official language) and have already lived in the country for a few years (ethnographic experience).

Or if you want to conduct an interdisciplinary research project, consider partnering up with collaborators whose expertise complements your own. Scientists from different fields might bring different skills and a fresh perspective or have access to the latest tech and equipment. Teaming up with reputable collaborators justifies the need for a study by increasing its credibility and likely impact.

When is the research rationale written?

You can write your research rationale before, or after, conducting the study.

In the first case, when you might have a new research idea, and you're applying for funding to implement it.

Or you're preparing a call for papers for a journal special issue or a conference. Here , for instance, the authors seek to collect studies on the impact of apathy on age-related neuropsychiatric disorders.

In the second case, you have completed the study and are writing a research paper for publication. Looking back, you explain why you did the study in question and how it worked out.

Although the research rationale is part of the introduction, it's best to write it at the end. Stand back from your study and look at it in the big picture. At this point, it's easier to convince your reader why your study was both necessary and important.

How long should a research rationale be?

The length of the research rationale is not fixed. Ideally, this will be determined by the guidelines (of your journal, sponsor etc.).

The prestigious journal Nature , for instance, calls for articles to be no more than 6 or 8 pages, depending on the content. The introduction should be around 200 words, and, as mentioned, two to three sentences serve as a brief account of the background and rationale of the study, and come at the end of the introduction.

If you're not provided guidelines, consider these factors:

  • Research document : In a thesis or book-length study, the research rationale will be longer than in a journal article. For example, the background and rationale of this book exploring the collective memory of World War I cover more than ten pages.
  • Research question : Research into a new sub-field may call for a longer or more detailed justification than a study that plugs a gap in literature.

Which verb tenses to use in the research rationale?

It's best to use the present tense. Though in a research proposal, the research rationale is likely written in the future tense, as you're describing the intended or expected outcomes of the research project (the gaps it will fill, the problems it will solve).

How to Write the Rationale of the Study in Research (Examples)

how to make a rationale in quantitative research

What is the Rationale of the Study?

The rationale of the study is the justification for taking on a given study. It explains the reason the study was conducted or should be conducted. This means the study rationale should explain to the reader or examiner why the study is/was necessary. It is also sometimes called the “purpose” or “justification” of a study. While this is not difficult to grasp in itself, you might wonder how the rationale of the study is different from your research question or from the statement of the problem of your study, and how it fits into the rest of your thesis or research paper. 

The rationale of the study links the background of the study to your specific research question and justifies the need for the latter on the basis of the former. In brief, you first provide and discuss existing data on the topic, and then you tell the reader, based on the background evidence you just presented, where you identified gaps or issues and why you think it is important to address those. The problem statement, lastly, is the formulation of the specific research question you choose to investigate, following logically from your rationale, and the approach you are planning to use to do that.

Table of Contents:

How to write a rationale for a research paper , how do you justify the need for a research study.

  • Study Rationale Example: Where Does It Go In Your Paper?

The basis for writing a research rationale is preliminary data or a clear description of an observation. If you are doing basic/theoretical research, then a literature review will help you identify gaps in current knowledge. In applied/practical research, you base your rationale on an existing issue with a certain process (e.g., vaccine proof registration) or practice (e.g., patient treatment) that is well documented and needs to be addressed. By presenting the reader with earlier evidence or observations, you can (and have to) convince them that you are not just repeating what other people have already done or said and that your ideas are not coming out of thin air. 

Once you have explained where you are coming from, you should justify the need for doing additional research–this is essentially the rationale of your study. Finally, when you have convinced the reader of the purpose of your work, you can end your introduction section with the statement of the problem of your research that contains clear aims and objectives and also briefly describes (and justifies) your methodological approach. 

When is the Rationale for Research Written?

The author can present the study rationale both before and after the research is conducted. 

  • Before conducting research : The study rationale is a central component of the research proposal . It represents the plan of your work, constructed before the study is actually executed.
  • Once research has been conducted : After the study is completed, the rationale is presented in a research article or  PhD dissertation  to explain why you focused on this specific research question. When writing the study rationale for this purpose, the author should link the rationale of the research to the aims and outcomes of the study.

What to Include in the Study Rationale

Although every study rationale is different and discusses different specific elements of a study’s method or approach, there are some elements that should be included to write a good rationale. Make sure to touch on the following:

  • A summary of conclusions from your review of the relevant literature
  • What is currently unknown (gaps in knowledge)
  • Inconclusive or contested results  from previous studies on the same or similar topic
  • The necessity to improve or build on previous research, such as to improve methodology or utilize newer techniques and/or technologies

There are different types of limitations that you can use to justify the need for your study. In applied/practical research, the justification for investigating something is always that an existing process/practice has a problem or is not satisfactory. Let’s say, for example, that people in a certain country/city/community commonly complain about hospital care on weekends (not enough staff, not enough attention, no decisions being made), but you looked into it and realized that nobody ever investigated whether these perceived problems are actually based on objective shortages/non-availabilities of care or whether the lower numbers of patients who are treated during weekends are commensurate with the provided services.

In this case, “lack of data” is your justification for digging deeper into the problem. Or, if it is obvious that there is a shortage of staff and provided services on weekends, you could decide to investigate which of the usual procedures are skipped during weekends as a result and what the negative consequences are. 

In basic/theoretical research, lack of knowledge is of course a common and accepted justification for additional research—but make sure that it is not your only motivation. “Nobody has ever done this” is only a convincing reason for a study if you explain to the reader why you think we should know more about this specific phenomenon. If there is earlier research but you think it has limitations, then those can usually be classified into “methodological”, “contextual”, and “conceptual” limitations. To identify such limitations, you can ask specific questions and let those questions guide you when you explain to the reader why your study was necessary:

Methodological limitations

  • Did earlier studies try but failed to measure/identify a specific phenomenon?
  • Was earlier research based on incorrect conceptualizations of variables?
  • Were earlier studies based on questionable operationalizations of key concepts?
  • Did earlier studies use questionable or inappropriate research designs?

Contextual limitations

  • Have recent changes in the studied problem made previous studies irrelevant?
  • Are you studying a new/particular context that previous findings do not apply to?

Conceptual limitations

  • Do previous findings only make sense within a specific framework or ideology?

Study Rationale Examples

Let’s look at an example from one of our earlier articles on the statement of the problem to clarify how your rationale fits into your introduction section. This is a very short introduction for a practical research study on the challenges of online learning. Your introduction might be much longer (especially the context/background section), and this example does not contain any sources (which you will have to provide for all claims you make and all earlier studies you cite)—but please pay attention to how the background presentation , rationale, and problem statement blend into each other in a logical way so that the reader can follow and has no reason to question your motivation or the foundation of your research.

Background presentation

Since the beginning of the Covid pandemic, most educational institutions around the world have transitioned to a fully online study model, at least during peak times of infections and social distancing measures. This transition has not been easy and even two years into the pandemic, problems with online teaching and studying persist (reference needed) . 

While the increasing gap between those with access to technology and equipment and those without access has been determined to be one of the main challenges (reference needed) , others claim that online learning offers more opportunities for many students by breaking down barriers of location and distance (reference needed) .  

Rationale of the study

Since teachers and students cannot wait for circumstances to go back to normal, the measures that schools and universities have implemented during the last two years, their advantages and disadvantages, and the impact of those measures on students’ progress, satisfaction, and well-being need to be understood so that improvements can be made and demographics that have been left behind can receive the support they need as soon as possible.

Statement of the problem

To identify what changes in the learning environment were considered the most challenging and how those changes relate to a variety of student outcome measures, we conducted surveys and interviews among teachers and students at ten institutions of higher education in four different major cities, two in the US (New York and Chicago), one in South Korea (Seoul), and one in the UK (London). Responses were analyzed with a focus on different student demographics and how they might have been affected differently by the current situation.

How long is a study rationale?

In a research article bound for journal publication, your rationale should not be longer than a few sentences (no longer than one brief paragraph). A  dissertation or thesis  usually allows for a longer description; depending on the length and nature of your document, this could be up to a couple of paragraphs in length. A completely novel or unconventional approach might warrant a longer and more detailed justification than an approach that slightly deviates from well-established methods and approaches.

How to Write a Rationale: A Guide for Research and Beyond

How to Write a Rationale: A Guide for Research and Beyond

Ever found yourself scratching your head, wondering how to justify your choice of a research topic or project? You’re not alone! Writing a rationale, which essentially means explaining the ‘why’ behind your decisions, is crucial to any research process. It’s like the secret sauce that adds flavour to your research recipe. So, the only thing you need to know is how to write a rationale.

Guide

What is a Rationale?

A rationale in research is essentially the foundation of your study. It serves as the justification for undertaking a particular research project. At its core, the rationale explains why the research was conducted or needs to be conducted, thus addressing a specific knowledge gap or research question.

Here’s a breakdown of the key elements involved in crafting a rationale:

Linking Background to Research Question: 

The rationale should connect the background of the study to your specific research question. It involves presenting and discussing existing data on your topic, identifying gaps or issues in the current understanding, and explaining why addressing them is important​.

Objectives and Significance: 

Your rationale should clearly outline your research objectives – what you hope to discover or achieve through the study. It should also emphasize the subject’s significance in your field and explain why more or better research is needed​.

Methodological Approach: 

The rationale should briefly describe your proposed research method , whether qualitative (descriptive) or quantitative (experimental), and justify this choice​.

Justifying the Need for Research: 

The rationale isn’t just about what you’re doing and why it’s necessary. It can involve highlighting methodological, contextual, or conceptual limitations in previous studies and explaining how your research aims to overcome these limitations. Essentially, you’re making a case for why your research fills a crucial gap in existing knowledge​​.

Presenting Before and After Research: 

Interestingly, the rationale can be presented before and after the research. Before the research, it forms a central part of the research proposal, setting out the plan for the work. After the research, it’s presented in a research article or dissertation to explain the focus on a specific research question and link it to the study’s aims and outcomes​.

Elements to Include: 

A good rationale should include a summary of conclusions from your literature review, identify what is currently unknown, discuss inconclusive or contested results from previous studies, and emphasize the necessity to improve or build on previous research​.

Creating a rationale is a vital part of the research process, as it not only sets the stage for your study but also convinces readers of the value and necessity of your work.

How to Write a Rationale:

Writing a rationale for your research is crucial in conducting and presenting your study. It involves explaining why your research is necessary and important. Here’s a guide to help you craft a compelling rationale:

Identify the Problem or Knowledge Gap: 

Begin by clearly stating the issue or gap in knowledge that your research aims to address. Explain why this problem is important and merits investigation. It is the foundation of your rationale and sets the stage for the need for your research.​

Review the Literature: 

Conduct a thorough review of existing literature on your topic. It helps you understand what research has already been done and what gaps or open questions exist. Your rationale should build on this background by highlighting these gaps and emphasizing the importance of addressing them​​​​.

Define Your Research Questions/Hypotheses: 

Based on your understanding of the problem and literature review, clearly state the research questions or hypotheses that your study aims to explore. These should logically stem from the identified gaps or issues.

Explain Your Research Approach: 

Describe the methods you will use for your research, including data collection and analysis techniques. Justify why these methods are appropriate for addressing your research questions or hypotheses​​.

Discuss the Potential Impact of Your Research:  Explain the significance of your study. Consider both theoretical contributions and practical implications. For instance, how does your research advance existing knowledge? Does it have real-world applications? Is it relevant to a specific field or community?​

Consider Ethical Considerations: 

If your research involves human or animal subjects, discuss the ethical aspects and how you plan to conduct your study responsibly​.

Contextualise Your Study: 

Justify the relevance of your research by explaining how it fits into the broader context. Connect your study to current trends, societal needs, or academic discussions​​.

Support with Evidence: 

Provide evidence or examples that underscore the need for your research. It could include citing relevant studies, statistics, or scenarios that illustrate the problem or gap your research addresses​.

Methodological, Contextual, and Conceptual Limitations: 

Address any limitations of previous research and how your study aims to overcome them. It can include methodological flaws in previous studies, changes in external factors that make past research less relevant, or the need to study a phenomenon within a new conceptual framework​.

Placement in Your Paper: 

Typically, the rationale is written toward the end of the introduction section of your paper, providing a logical lead-in to your research questions and methodology​​.

By following these steps and considering your audience’s perspective, you can write a strong and compelling rationale that clearly communicates the significance and necessity of your research project.

Frequently Asked Questions:

What makes a good research rationale.

A good rationale clearly identifies a gap in existing knowledge, builds on previous research, and outlines why your study is necessary and significant.

How detailed should my literature review be in the rationale?

Your literature review should be comprehensive enough to highlight the gaps your research aims to fill, but it should not overshadow the rationale itself.

Conclusion: 

A well-crafted rationale is your ticket to making your research stand out. It’s about bridging gaps, challenging norms, and paving the way for new discoveries. So go ahead, make your rationale the cornerstone of your research narrative!

Up until working with Casey, we had only had poor to mediocre experiences outsourcing work to agencies. Casey & the team at CJ&CO are the exception to the rule.

Communication was beyond great, his understanding of our vision was phenomenal, and instead of needing babysitting like the other agencies we worked with, he was not only completely dependable but also gave us sound suggestions on how to get better results, at the risk of us not needing him for the initial job we requested (absolute gem).

This has truly been the first time we worked with someone outside of our business that quickly grasped our vision, and that I could completely forget about and would still deliver above expectations.

I honestly can't wait to work in many more projects together!

A Practical Guide to Writing Quantitative and Qualitative Research Questions and Hypotheses in Scholarly Articles

The development of research questions and the subsequent hypotheses are prerequisites to defining the main research purpose and specific objectives of a study. Consequently, these objectives determine the study design and research outcome. The development of research questions is a process based on knowledge of current trends, cutting-edge studies, and technological advances in the research field. Excellent research questions are focused and require a comprehensive literature search and in-depth understanding of the problem being investigated. Initially, research questions may be written as descriptive questions which could be developed into inferential questions. These questions must be specific and concise to provide a clear foundation for developing hypotheses. Hypotheses are more formal predictions about the research outcomes. These specify the possible results that may or may not be expected regarding the relationship between groups. Thus, research questions and hypotheses clarify the main purpose and specific objectives of the study, which in turn dictate the design of the study, its direction, and outcome. Studies developed from good research questions and hypotheses will have trustworthy outcomes with wide-ranging social and health implications.

INTRODUCTION

Scientific research is usually initiated by posing evidenced-based research questions which are then explicitly restated as hypotheses. 1 , 2 The hypotheses provide directions to guide the study, solutions, explanations, and expected results. 3 , 4 Both research questions and hypotheses are essentially formulated based on conventional theories and real-world processes, which allow the inception of novel studies and the ethical testing of ideas. 5 , 6

It is crucial to have knowledge of both quantitative and qualitative research 2 as both types of research involve writing research questions and hypotheses. 7 However, these crucial elements of research are sometimes overlooked; if not overlooked, then framed without the forethought and meticulous attention it needs. Planning and careful consideration are needed when developing quantitative or qualitative research, particularly when conceptualizing research questions and hypotheses. 4

There is a continuing need to support researchers in the creation of innovative research questions and hypotheses, as well as for journal articles that carefully review these elements. 1 When research questions and hypotheses are not carefully thought of, unethical studies and poor outcomes usually ensue. Carefully formulated research questions and hypotheses define well-founded objectives, which in turn determine the appropriate design, course, and outcome of the study. This article then aims to discuss in detail the various aspects of crafting research questions and hypotheses, with the goal of guiding researchers as they develop their own. Examples from the authors and peer-reviewed scientific articles in the healthcare field are provided to illustrate key points.

DEFINITIONS AND RELATIONSHIP OF RESEARCH QUESTIONS AND HYPOTHESES

A research question is what a study aims to answer after data analysis and interpretation. The answer is written in length in the discussion section of the paper. Thus, the research question gives a preview of the different parts and variables of the study meant to address the problem posed in the research question. 1 An excellent research question clarifies the research writing while facilitating understanding of the research topic, objective, scope, and limitations of the study. 5

On the other hand, a research hypothesis is an educated statement of an expected outcome. This statement is based on background research and current knowledge. 8 , 9 The research hypothesis makes a specific prediction about a new phenomenon 10 or a formal statement on the expected relationship between an independent variable and a dependent variable. 3 , 11 It provides a tentative answer to the research question to be tested or explored. 4

Hypotheses employ reasoning to predict a theory-based outcome. 10 These can also be developed from theories by focusing on components of theories that have not yet been observed. 10 The validity of hypotheses is often based on the testability of the prediction made in a reproducible experiment. 8

Conversely, hypotheses can also be rephrased as research questions. Several hypotheses based on existing theories and knowledge may be needed to answer a research question. Developing ethical research questions and hypotheses creates a research design that has logical relationships among variables. These relationships serve as a solid foundation for the conduct of the study. 4 , 11 Haphazardly constructed research questions can result in poorly formulated hypotheses and improper study designs, leading to unreliable results. Thus, the formulations of relevant research questions and verifiable hypotheses are crucial when beginning research. 12

CHARACTERISTICS OF GOOD RESEARCH QUESTIONS AND HYPOTHESES

Excellent research questions are specific and focused. These integrate collective data and observations to confirm or refute the subsequent hypotheses. Well-constructed hypotheses are based on previous reports and verify the research context. These are realistic, in-depth, sufficiently complex, and reproducible. More importantly, these hypotheses can be addressed and tested. 13

There are several characteristics of well-developed hypotheses. Good hypotheses are 1) empirically testable 7 , 10 , 11 , 13 ; 2) backed by preliminary evidence 9 ; 3) testable by ethical research 7 , 9 ; 4) based on original ideas 9 ; 5) have evidenced-based logical reasoning 10 ; and 6) can be predicted. 11 Good hypotheses can infer ethical and positive implications, indicating the presence of a relationship or effect relevant to the research theme. 7 , 11 These are initially developed from a general theory and branch into specific hypotheses by deductive reasoning. In the absence of a theory to base the hypotheses, inductive reasoning based on specific observations or findings form more general hypotheses. 10

TYPES OF RESEARCH QUESTIONS AND HYPOTHESES

Research questions and hypotheses are developed according to the type of research, which can be broadly classified into quantitative and qualitative research. We provide a summary of the types of research questions and hypotheses under quantitative and qualitative research categories in Table 1 .

Research questions in quantitative research

In quantitative research, research questions inquire about the relationships among variables being investigated and are usually framed at the start of the study. These are precise and typically linked to the subject population, dependent and independent variables, and research design. 1 Research questions may also attempt to describe the behavior of a population in relation to one or more variables, or describe the characteristics of variables to be measured ( descriptive research questions ). 1 , 5 , 14 These questions may also aim to discover differences between groups within the context of an outcome variable ( comparative research questions ), 1 , 5 , 14 or elucidate trends and interactions among variables ( relationship research questions ). 1 , 5 We provide examples of descriptive, comparative, and relationship research questions in quantitative research in Table 2 .

Quantitative research questions
Descriptive research question
- Measures responses of subjects to variables
- Presents variables to measure, analyze, or assess
What is the proportion of resident doctors in the hospital who have mastered ultrasonography (response of subjects to a variable) as a diagnostic technique in their clinical training?
Comparative research question
- Clarifies difference between one group with outcome variable and another group without outcome variable
Is there a difference in the reduction of lung metastasis in osteosarcoma patients who received the vitamin D adjunctive therapy (group with outcome variable) compared with osteosarcoma patients who did not receive the vitamin D adjunctive therapy (group without outcome variable)?
- Compares the effects of variables
How does the vitamin D analogue 22-Oxacalcitriol (variable 1) mimic the antiproliferative activity of 1,25-Dihydroxyvitamin D (variable 2) in osteosarcoma cells?
Relationship research question
- Defines trends, association, relationships, or interactions between dependent variable and independent variable
Is there a relationship between the number of medical student suicide (dependent variable) and the level of medical student stress (independent variable) in Japan during the first wave of the COVID-19 pandemic?

Hypotheses in quantitative research

In quantitative research, hypotheses predict the expected relationships among variables. 15 Relationships among variables that can be predicted include 1) between a single dependent variable and a single independent variable ( simple hypothesis ) or 2) between two or more independent and dependent variables ( complex hypothesis ). 4 , 11 Hypotheses may also specify the expected direction to be followed and imply an intellectual commitment to a particular outcome ( directional hypothesis ) 4 . On the other hand, hypotheses may not predict the exact direction and are used in the absence of a theory, or when findings contradict previous studies ( non-directional hypothesis ). 4 In addition, hypotheses can 1) define interdependency between variables ( associative hypothesis ), 4 2) propose an effect on the dependent variable from manipulation of the independent variable ( causal hypothesis ), 4 3) state a negative relationship between two variables ( null hypothesis ), 4 , 11 , 15 4) replace the working hypothesis if rejected ( alternative hypothesis ), 15 explain the relationship of phenomena to possibly generate a theory ( working hypothesis ), 11 5) involve quantifiable variables that can be tested statistically ( statistical hypothesis ), 11 6) or express a relationship whose interlinks can be verified logically ( logical hypothesis ). 11 We provide examples of simple, complex, directional, non-directional, associative, causal, null, alternative, working, statistical, and logical hypotheses in quantitative research, as well as the definition of quantitative hypothesis-testing research in Table 3 .

Quantitative research hypotheses
Simple hypothesis
- Predicts relationship between single dependent variable and single independent variable
If the dose of the new medication (single independent variable) is high, blood pressure (single dependent variable) is lowered.
Complex hypothesis
- Foretells relationship between two or more independent and dependent variables
The higher the use of anticancer drugs, radiation therapy, and adjunctive agents (3 independent variables), the higher would be the survival rate (1 dependent variable).
Directional hypothesis
- Identifies study direction based on theory towards particular outcome to clarify relationship between variables
Privately funded research projects will have a larger international scope (study direction) than publicly funded research projects.
Non-directional hypothesis
- Nature of relationship between two variables or exact study direction is not identified
- Does not involve a theory
Women and men are different in terms of helpfulness. (Exact study direction is not identified)
Associative hypothesis
- Describes variable interdependency
- Change in one variable causes change in another variable
A larger number of people vaccinated against COVID-19 in the region (change in independent variable) will reduce the region’s incidence of COVID-19 infection (change in dependent variable).
Causal hypothesis
- An effect on dependent variable is predicted from manipulation of independent variable
A change into a high-fiber diet (independent variable) will reduce the blood sugar level (dependent variable) of the patient.
Null hypothesis
- A negative statement indicating no relationship or difference between 2 variables
There is no significant difference in the severity of pulmonary metastases between the new drug (variable 1) and the current drug (variable 2).
Alternative hypothesis
- Following a null hypothesis, an alternative hypothesis predicts a relationship between 2 study variables
The new drug (variable 1) is better on average in reducing the level of pain from pulmonary metastasis than the current drug (variable 2).
Working hypothesis
- A hypothesis that is initially accepted for further research to produce a feasible theory
Dairy cows fed with concentrates of different formulations will produce different amounts of milk.
Statistical hypothesis
- Assumption about the value of population parameter or relationship among several population characteristics
- Validity tested by a statistical experiment or analysis
The mean recovery rate from COVID-19 infection (value of population parameter) is not significantly different between population 1 and population 2.
There is a positive correlation between the level of stress at the workplace and the number of suicides (population characteristics) among working people in Japan.
Logical hypothesis
- Offers or proposes an explanation with limited or no extensive evidence
If healthcare workers provide more educational programs about contraception methods, the number of adolescent pregnancies will be less.
Hypothesis-testing (Quantitative hypothesis-testing research)
- Quantitative research uses deductive reasoning.
- This involves the formation of a hypothesis, collection of data in the investigation of the problem, analysis and use of the data from the investigation, and drawing of conclusions to validate or nullify the hypotheses.

Research questions in qualitative research

Unlike research questions in quantitative research, research questions in qualitative research are usually continuously reviewed and reformulated. The central question and associated subquestions are stated more than the hypotheses. 15 The central question broadly explores a complex set of factors surrounding the central phenomenon, aiming to present the varied perspectives of participants. 15

There are varied goals for which qualitative research questions are developed. These questions can function in several ways, such as to 1) identify and describe existing conditions ( contextual research question s); 2) describe a phenomenon ( descriptive research questions ); 3) assess the effectiveness of existing methods, protocols, theories, or procedures ( evaluation research questions ); 4) examine a phenomenon or analyze the reasons or relationships between subjects or phenomena ( explanatory research questions ); or 5) focus on unknown aspects of a particular topic ( exploratory research questions ). 5 In addition, some qualitative research questions provide new ideas for the development of theories and actions ( generative research questions ) or advance specific ideologies of a position ( ideological research questions ). 1 Other qualitative research questions may build on a body of existing literature and become working guidelines ( ethnographic research questions ). Research questions may also be broadly stated without specific reference to the existing literature or a typology of questions ( phenomenological research questions ), may be directed towards generating a theory of some process ( grounded theory questions ), or may address a description of the case and the emerging themes ( qualitative case study questions ). 15 We provide examples of contextual, descriptive, evaluation, explanatory, exploratory, generative, ideological, ethnographic, phenomenological, grounded theory, and qualitative case study research questions in qualitative research in Table 4 , and the definition of qualitative hypothesis-generating research in Table 5 .

Qualitative research questions
Contextual research question
- Ask the nature of what already exists
- Individuals or groups function to further clarify and understand the natural context of real-world problems
What are the experiences of nurses working night shifts in healthcare during the COVID-19 pandemic? (natural context of real-world problems)
Descriptive research question
- Aims to describe a phenomenon
What are the different forms of disrespect and abuse (phenomenon) experienced by Tanzanian women when giving birth in healthcare facilities?
Evaluation research question
- Examines the effectiveness of existing practice or accepted frameworks
How effective are decision aids (effectiveness of existing practice) in helping decide whether to give birth at home or in a healthcare facility?
Explanatory research question
- Clarifies a previously studied phenomenon and explains why it occurs
Why is there an increase in teenage pregnancy (phenomenon) in Tanzania?
Exploratory research question
- Explores areas that have not been fully investigated to have a deeper understanding of the research problem
What factors affect the mental health of medical students (areas that have not yet been fully investigated) during the COVID-19 pandemic?
Generative research question
- Develops an in-depth understanding of people’s behavior by asking ‘how would’ or ‘what if’ to identify problems and find solutions
How would the extensive research experience of the behavior of new staff impact the success of the novel drug initiative?
Ideological research question
- Aims to advance specific ideas or ideologies of a position
Are Japanese nurses who volunteer in remote African hospitals able to promote humanized care of patients (specific ideas or ideologies) in the areas of safe patient environment, respect of patient privacy, and provision of accurate information related to health and care?
Ethnographic research question
- Clarifies peoples’ nature, activities, their interactions, and the outcomes of their actions in specific settings
What are the demographic characteristics, rehabilitative treatments, community interactions, and disease outcomes (nature, activities, their interactions, and the outcomes) of people in China who are suffering from pneumoconiosis?
Phenomenological research question
- Knows more about the phenomena that have impacted an individual
What are the lived experiences of parents who have been living with and caring for children with a diagnosis of autism? (phenomena that have impacted an individual)
Grounded theory question
- Focuses on social processes asking about what happens and how people interact, or uncovering social relationships and behaviors of groups
What are the problems that pregnant adolescents face in terms of social and cultural norms (social processes), and how can these be addressed?
Qualitative case study question
- Assesses a phenomenon using different sources of data to answer “why” and “how” questions
- Considers how the phenomenon is influenced by its contextual situation.
How does quitting work and assuming the role of a full-time mother (phenomenon assessed) change the lives of women in Japan?
Qualitative research hypotheses
Hypothesis-generating (Qualitative hypothesis-generating research)
- Qualitative research uses inductive reasoning.
- This involves data collection from study participants or the literature regarding a phenomenon of interest, using the collected data to develop a formal hypothesis, and using the formal hypothesis as a framework for testing the hypothesis.
- Qualitative exploratory studies explore areas deeper, clarifying subjective experience and allowing formulation of a formal hypothesis potentially testable in a future quantitative approach.

Qualitative studies usually pose at least one central research question and several subquestions starting with How or What . These research questions use exploratory verbs such as explore or describe . These also focus on one central phenomenon of interest, and may mention the participants and research site. 15

Hypotheses in qualitative research

Hypotheses in qualitative research are stated in the form of a clear statement concerning the problem to be investigated. Unlike in quantitative research where hypotheses are usually developed to be tested, qualitative research can lead to both hypothesis-testing and hypothesis-generating outcomes. 2 When studies require both quantitative and qualitative research questions, this suggests an integrative process between both research methods wherein a single mixed-methods research question can be developed. 1

FRAMEWORKS FOR DEVELOPING RESEARCH QUESTIONS AND HYPOTHESES

Research questions followed by hypotheses should be developed before the start of the study. 1 , 12 , 14 It is crucial to develop feasible research questions on a topic that is interesting to both the researcher and the scientific community. This can be achieved by a meticulous review of previous and current studies to establish a novel topic. Specific areas are subsequently focused on to generate ethical research questions. The relevance of the research questions is evaluated in terms of clarity of the resulting data, specificity of the methodology, objectivity of the outcome, depth of the research, and impact of the study. 1 , 5 These aspects constitute the FINER criteria (i.e., Feasible, Interesting, Novel, Ethical, and Relevant). 1 Clarity and effectiveness are achieved if research questions meet the FINER criteria. In addition to the FINER criteria, Ratan et al. described focus, complexity, novelty, feasibility, and measurability for evaluating the effectiveness of research questions. 14

The PICOT and PEO frameworks are also used when developing research questions. 1 The following elements are addressed in these frameworks, PICOT: P-population/patients/problem, I-intervention or indicator being studied, C-comparison group, O-outcome of interest, and T-timeframe of the study; PEO: P-population being studied, E-exposure to preexisting conditions, and O-outcome of interest. 1 Research questions are also considered good if these meet the “FINERMAPS” framework: Feasible, Interesting, Novel, Ethical, Relevant, Manageable, Appropriate, Potential value/publishable, and Systematic. 14

As we indicated earlier, research questions and hypotheses that are not carefully formulated result in unethical studies or poor outcomes. To illustrate this, we provide some examples of ambiguous research question and hypotheses that result in unclear and weak research objectives in quantitative research ( Table 6 ) 16 and qualitative research ( Table 7 ) 17 , and how to transform these ambiguous research question(s) and hypothesis(es) into clear and good statements.

VariablesUnclear and weak statement (Statement 1) Clear and good statement (Statement 2) Points to avoid
Research questionWhich is more effective between smoke moxibustion and smokeless moxibustion?“Moreover, regarding smoke moxibustion versus smokeless moxibustion, it remains unclear which is more effective, safe, and acceptable to pregnant women, and whether there is any difference in the amount of heat generated.” 1) Vague and unfocused questions
2) Closed questions simply answerable by yes or no
3) Questions requiring a simple choice
HypothesisThe smoke moxibustion group will have higher cephalic presentation.“Hypothesis 1. The smoke moxibustion stick group (SM group) and smokeless moxibustion stick group (-SLM group) will have higher rates of cephalic presentation after treatment than the control group.1) Unverifiable hypotheses
Hypothesis 2. The SM group and SLM group will have higher rates of cephalic presentation at birth than the control group.2) Incompletely stated groups of comparison
Hypothesis 3. There will be no significant differences in the well-being of the mother and child among the three groups in terms of the following outcomes: premature birth, premature rupture of membranes (PROM) at < 37 weeks, Apgar score < 7 at 5 min, umbilical cord blood pH < 7.1, admission to neonatal intensive care unit (NICU), and intrauterine fetal death.” 3) Insufficiently described variables or outcomes
Research objectiveTo determine which is more effective between smoke moxibustion and smokeless moxibustion.“The specific aims of this pilot study were (a) to compare the effects of smoke moxibustion and smokeless moxibustion treatments with the control group as a possible supplement to ECV for converting breech presentation to cephalic presentation and increasing adherence to the newly obtained cephalic position, and (b) to assess the effects of these treatments on the well-being of the mother and child.” 1) Poor understanding of the research question and hypotheses
2) Insufficient description of population, variables, or study outcomes

CONSTRUCTING RESEARCH QUESTIONS AND HYPOTHESES

To construct effective research questions and hypotheses, it is very important to 1) clarify the background and 2) identify the research problem at the outset of the research, within a specific timeframe. 9 Then, 3) review or conduct preliminary research to collect all available knowledge about the possible research questions by studying theories and previous studies. 18 Afterwards, 4) construct research questions to investigate the research problem. Identify variables to be accessed from the research questions 4 and make operational definitions of constructs from the research problem and questions. Thereafter, 5) construct specific deductive or inductive predictions in the form of hypotheses. 4 Finally, 6) state the study aims . This general flow for constructing effective research questions and hypotheses prior to conducting research is shown in Fig. 1 .

Research questions are used more frequently in qualitative research than objectives or hypotheses. 3 These questions seek to discover, understand, explore or describe experiences by asking “What” or “How.” The questions are open-ended to elicit a description rather than to relate variables or compare groups. The questions are continually reviewed, reformulated, and changed during the qualitative study. 3 Research questions are also used more frequently in survey projects than hypotheses in experiments in quantitative research to compare variables and their relationships.

Hypotheses are constructed based on the variables identified and as an if-then statement, following the template, ‘If a specific action is taken, then a certain outcome is expected.’ At this stage, some ideas regarding expectations from the research to be conducted must be drawn. 18 Then, the variables to be manipulated (independent) and influenced (dependent) are defined. 4 Thereafter, the hypothesis is stated and refined, and reproducible data tailored to the hypothesis are identified, collected, and analyzed. 4 The hypotheses must be testable and specific, 18 and should describe the variables and their relationships, the specific group being studied, and the predicted research outcome. 18 Hypotheses construction involves a testable proposition to be deduced from theory, and independent and dependent variables to be separated and measured separately. 3 Therefore, good hypotheses must be based on good research questions constructed at the start of a study or trial. 12

In summary, research questions are constructed after establishing the background of the study. Hypotheses are then developed based on the research questions. Thus, it is crucial to have excellent research questions to generate superior hypotheses. In turn, these would determine the research objectives and the design of the study, and ultimately, the outcome of the research. 12 Algorithms for building research questions and hypotheses are shown in Fig. 2 for quantitative research and in Fig. 3 for qualitative research.

EXAMPLES OF RESEARCH QUESTIONS FROM PUBLISHED ARTICLES

  • EXAMPLE 1. Descriptive research question (quantitative research)
  • - Presents research variables to be assessed (distinct phenotypes and subphenotypes)
  • “BACKGROUND: Since COVID-19 was identified, its clinical and biological heterogeneity has been recognized. Identifying COVID-19 phenotypes might help guide basic, clinical, and translational research efforts.
  • RESEARCH QUESTION: Does the clinical spectrum of patients with COVID-19 contain distinct phenotypes and subphenotypes? ” 19
  • EXAMPLE 2. Relationship research question (quantitative research)
  • - Shows interactions between dependent variable (static postural control) and independent variable (peripheral visual field loss)
  • “Background: Integration of visual, vestibular, and proprioceptive sensations contributes to postural control. People with peripheral visual field loss have serious postural instability. However, the directional specificity of postural stability and sensory reweighting caused by gradual peripheral visual field loss remain unclear.
  • Research question: What are the effects of peripheral visual field loss on static postural control ?” 20
  • EXAMPLE 3. Comparative research question (quantitative research)
  • - Clarifies the difference among groups with an outcome variable (patients enrolled in COMPERA with moderate PH or severe PH in COPD) and another group without the outcome variable (patients with idiopathic pulmonary arterial hypertension (IPAH))
  • “BACKGROUND: Pulmonary hypertension (PH) in COPD is a poorly investigated clinical condition.
  • RESEARCH QUESTION: Which factors determine the outcome of PH in COPD?
  • STUDY DESIGN AND METHODS: We analyzed the characteristics and outcome of patients enrolled in the Comparative, Prospective Registry of Newly Initiated Therapies for Pulmonary Hypertension (COMPERA) with moderate or severe PH in COPD as defined during the 6th PH World Symposium who received medical therapy for PH and compared them with patients with idiopathic pulmonary arterial hypertension (IPAH) .” 21
  • EXAMPLE 4. Exploratory research question (qualitative research)
  • - Explores areas that have not been fully investigated (perspectives of families and children who receive care in clinic-based child obesity treatment) to have a deeper understanding of the research problem
  • “Problem: Interventions for children with obesity lead to only modest improvements in BMI and long-term outcomes, and data are limited on the perspectives of families of children with obesity in clinic-based treatment. This scoping review seeks to answer the question: What is known about the perspectives of families and children who receive care in clinic-based child obesity treatment? This review aims to explore the scope of perspectives reported by families of children with obesity who have received individualized outpatient clinic-based obesity treatment.” 22
  • EXAMPLE 5. Relationship research question (quantitative research)
  • - Defines interactions between dependent variable (use of ankle strategies) and independent variable (changes in muscle tone)
  • “Background: To maintain an upright standing posture against external disturbances, the human body mainly employs two types of postural control strategies: “ankle strategy” and “hip strategy.” While it has been reported that the magnitude of the disturbance alters the use of postural control strategies, it has not been elucidated how the level of muscle tone, one of the crucial parameters of bodily function, determines the use of each strategy. We have previously confirmed using forward dynamics simulations of human musculoskeletal models that an increased muscle tone promotes the use of ankle strategies. The objective of the present study was to experimentally evaluate a hypothesis: an increased muscle tone promotes the use of ankle strategies. Research question: Do changes in the muscle tone affect the use of ankle strategies ?” 23

EXAMPLES OF HYPOTHESES IN PUBLISHED ARTICLES

  • EXAMPLE 1. Working hypothesis (quantitative research)
  • - A hypothesis that is initially accepted for further research to produce a feasible theory
  • “As fever may have benefit in shortening the duration of viral illness, it is plausible to hypothesize that the antipyretic efficacy of ibuprofen may be hindering the benefits of a fever response when taken during the early stages of COVID-19 illness .” 24
  • “In conclusion, it is plausible to hypothesize that the antipyretic efficacy of ibuprofen may be hindering the benefits of a fever response . The difference in perceived safety of these agents in COVID-19 illness could be related to the more potent efficacy to reduce fever with ibuprofen compared to acetaminophen. Compelling data on the benefit of fever warrant further research and review to determine when to treat or withhold ibuprofen for early stage fever for COVID-19 and other related viral illnesses .” 24
  • EXAMPLE 2. Exploratory hypothesis (qualitative research)
  • - Explores particular areas deeper to clarify subjective experience and develop a formal hypothesis potentially testable in a future quantitative approach
  • “We hypothesized that when thinking about a past experience of help-seeking, a self distancing prompt would cause increased help-seeking intentions and more favorable help-seeking outcome expectations .” 25
  • “Conclusion
  • Although a priori hypotheses were not supported, further research is warranted as results indicate the potential for using self-distancing approaches to increasing help-seeking among some people with depressive symptomatology.” 25
  • EXAMPLE 3. Hypothesis-generating research to establish a framework for hypothesis testing (qualitative research)
  • “We hypothesize that compassionate care is beneficial for patients (better outcomes), healthcare systems and payers (lower costs), and healthcare providers (lower burnout). ” 26
  • Compassionomics is the branch of knowledge and scientific study of the effects of compassionate healthcare. Our main hypotheses are that compassionate healthcare is beneficial for (1) patients, by improving clinical outcomes, (2) healthcare systems and payers, by supporting financial sustainability, and (3) HCPs, by lowering burnout and promoting resilience and well-being. The purpose of this paper is to establish a scientific framework for testing the hypotheses above . If these hypotheses are confirmed through rigorous research, compassionomics will belong in the science of evidence-based medicine, with major implications for all healthcare domains.” 26
  • EXAMPLE 4. Statistical hypothesis (quantitative research)
  • - An assumption is made about the relationship among several population characteristics ( gender differences in sociodemographic and clinical characteristics of adults with ADHD ). Validity is tested by statistical experiment or analysis ( chi-square test, Students t-test, and logistic regression analysis)
  • “Our research investigated gender differences in sociodemographic and clinical characteristics of adults with ADHD in a Japanese clinical sample. Due to unique Japanese cultural ideals and expectations of women's behavior that are in opposition to ADHD symptoms, we hypothesized that women with ADHD experience more difficulties and present more dysfunctions than men . We tested the following hypotheses: first, women with ADHD have more comorbidities than men with ADHD; second, women with ADHD experience more social hardships than men, such as having less full-time employment and being more likely to be divorced.” 27
  • “Statistical Analysis
  • ( text omitted ) Between-gender comparisons were made using the chi-squared test for categorical variables and Students t-test for continuous variables…( text omitted ). A logistic regression analysis was performed for employment status, marital status, and comorbidity to evaluate the independent effects of gender on these dependent variables.” 27

EXAMPLES OF HYPOTHESIS AS WRITTEN IN PUBLISHED ARTICLES IN RELATION TO OTHER PARTS

  • EXAMPLE 1. Background, hypotheses, and aims are provided
  • “Pregnant women need skilled care during pregnancy and childbirth, but that skilled care is often delayed in some countries …( text omitted ). The focused antenatal care (FANC) model of WHO recommends that nurses provide information or counseling to all pregnant women …( text omitted ). Job aids are visual support materials that provide the right kind of information using graphics and words in a simple and yet effective manner. When nurses are not highly trained or have many work details to attend to, these job aids can serve as a content reminder for the nurses and can be used for educating their patients (Jennings, Yebadokpo, Affo, & Agbogbe, 2010) ( text omitted ). Importantly, additional evidence is needed to confirm how job aids can further improve the quality of ANC counseling by health workers in maternal care …( text omitted )” 28
  • “ This has led us to hypothesize that the quality of ANC counseling would be better if supported by job aids. Consequently, a better quality of ANC counseling is expected to produce higher levels of awareness concerning the danger signs of pregnancy and a more favorable impression of the caring behavior of nurses .” 28
  • “This study aimed to examine the differences in the responses of pregnant women to a job aid-supported intervention during ANC visit in terms of 1) their understanding of the danger signs of pregnancy and 2) their impression of the caring behaviors of nurses to pregnant women in rural Tanzania.” 28
  • EXAMPLE 2. Background, hypotheses, and aims are provided
  • “We conducted a two-arm randomized controlled trial (RCT) to evaluate and compare changes in salivary cortisol and oxytocin levels of first-time pregnant women between experimental and control groups. The women in the experimental group touched and held an infant for 30 min (experimental intervention protocol), whereas those in the control group watched a DVD movie of an infant (control intervention protocol). The primary outcome was salivary cortisol level and the secondary outcome was salivary oxytocin level.” 29
  • “ We hypothesize that at 30 min after touching and holding an infant, the salivary cortisol level will significantly decrease and the salivary oxytocin level will increase in the experimental group compared with the control group .” 29
  • EXAMPLE 3. Background, aim, and hypothesis are provided
  • “In countries where the maternal mortality ratio remains high, antenatal education to increase Birth Preparedness and Complication Readiness (BPCR) is considered one of the top priorities [1]. BPCR includes birth plans during the antenatal period, such as the birthplace, birth attendant, transportation, health facility for complications, expenses, and birth materials, as well as family coordination to achieve such birth plans. In Tanzania, although increasing, only about half of all pregnant women attend an antenatal clinic more than four times [4]. Moreover, the information provided during antenatal care (ANC) is insufficient. In the resource-poor settings, antenatal group education is a potential approach because of the limited time for individual counseling at antenatal clinics.” 30
  • “This study aimed to evaluate an antenatal group education program among pregnant women and their families with respect to birth-preparedness and maternal and infant outcomes in rural villages of Tanzania.” 30
  • “ The study hypothesis was if Tanzanian pregnant women and their families received a family-oriented antenatal group education, they would (1) have a higher level of BPCR, (2) attend antenatal clinic four or more times, (3) give birth in a health facility, (4) have less complications of women at birth, and (5) have less complications and deaths of infants than those who did not receive the education .” 30

Research questions and hypotheses are crucial components to any type of research, whether quantitative or qualitative. These questions should be developed at the very beginning of the study. Excellent research questions lead to superior hypotheses, which, like a compass, set the direction of research, and can often determine the successful conduct of the study. Many research studies have floundered because the development of research questions and subsequent hypotheses was not given the thought and meticulous attention needed. The development of research questions and hypotheses is an iterative process based on extensive knowledge of the literature and insightful grasp of the knowledge gap. Focused, concise, and specific research questions provide a strong foundation for constructing hypotheses which serve as formal predictions about the research outcomes. Research questions and hypotheses are crucial elements of research that should not be overlooked. They should be carefully thought of and constructed when planning research. This avoids unethical studies and poor outcomes by defining well-founded objectives that determine the design, course, and outcome of the study.

Knowledge and curiosity lays the foundation of scientific progress. The quest for knowledge has always been a timeless endeavor. Scholars seek reasons to explain the phenomena they observe, paving way for development of research. Every investigation should offer clarity and a well-defined rationale in research is a cornerstone upon which the entire study can be built.

Research rationale is the heartbeat of every academic pursuit as it guides the researchers to unlock the untouched areas of their field. Additionally, it illuminates the gaps in the existing knowledge, and identifies the potential contributions that the study aims to make.

What Is Research Rationale and When Is It Written

Research rationale is the “why” behind every academic research. It not only frames the study but also outlines its objectives , questions, and expected outcomes. Additionally, it helps to identify the potential limitations of the study . It serves as a lighthouse for researchers that guides through data collection and analysis, ensuring their efforts remain focused and purposeful. Typically, a rationale is written at the beginning of the research proposal or research paper . It is an essential component of the introduction section and provides the foundation for the entire study. Furthermore, it provides a clear understanding of the purpose and significance of the research to the readers before delving into the specific details of the study. In some cases, the rationale is written before the methodology, data analysis, and other sections. Also, it serves as the justification for the research, and how it contributes to the field. Defining a research rationale can help a researcher in following ways:

Define Your Research Rationale

1. Justification of a Research Problem

  • Research rationale helps to understand the essence of a research problem.
  • It designs the right approach to solve a problem. This aspect is particularly important for applied research, where the outcomes can have real-world relevance and impact.
  • Also, it explains why the study is worth conducting and why resources should be allocated to pursue it.
  • Additionally, it guides a researcher to highlight the benefits and implications of a strategy.

2. Elimination of Literature Gap

  • Research rationale helps to ideate new topics which are less addressed.
  • Additionally, it offers fresh perspectives on existing research and discusses the shortcomings in previous studies.
  • It shows that your study aims to contribute to filling these gaps and advancing the field’s understanding.

3. Originality and Novelty

  • The rationale highlights the unique aspects of your research and how it differs from previous studies.
  • Furthermore, it explains why your research adds something new to the field and how it expands upon existing knowledge.
  • It highlights how your findings might contribute to a better understanding of a particular issue or problem and potentially lead to positive changes.
  • Besides these benefits, it provides a personal motivation to the researchers. In some cases, researchers might have personal experiences or interests that drive their desire to investigate a particular topic.

4. An Increase in Chances of Funding

  • It is essential to convince funding agencies , supervisors, or reviewers, that a research is worth pursuing.
  • Therefore, a good rationale can get your research approved for funding and increases your chances of getting published in journals; as it addresses the potential knowledge gap in existing research.

Overall, research rationale is essential for providing a clear and convincing argument for the value and importance of your research study, setting the stage for the rest of the research proposal or manuscript. Furthermore, it helps establish the context for your work and enables others to understand the purpose and potential impact of your research.

5 Key Elements of a Research Rationale

After writing the initial draft, it is essential to review and revise the research rationale to ensure that it effectively communicates the purpose of your research. The research rationale should be persuasive and compelling, convincing readers that your study is worthwhile and deserves their attention.

How Long Should a Research Rationale be?

Although there is no pre-defined length for a rationale in research, its length may vary depending on the specific requirements of the research project. It also depends on the academic institution or organization, and the guidelines set by the research advisor or funding agency. In general, a research rationale is usually a concise and focused document.

Typically, it ranges from a few paragraphs to a few pages, but it is usually recommended to keep it as crisp as possible while ensuring all the essential elements are adequately covered. The length of a research rationale can be roughly as follows:

1. For Research Proposal:

A. Around 1 to 3 pages

B. Ensure clear and comprehensive explanation of the research question, its significance, literature review , and methodological approach.

2. Thesis or Dissertation:

A. Around 3 to 5 pages

B. Ensure an extensive coverage of the literature review, theoretical framework, and research objectives to provide a robust justification for the study.

3. Journal Article:

A. Usually concise. Ranges from few paragraphs to one page

B. The research rationale is typically included as part of the introduction section

How To Make Rationale in Research: A Thorough Overview

Struggling to make the right rationale for your research? Learn how to make rationale in research to create the perfect plan for success.

' src=

Any academic or scientific discipline relies heavily on research. However, in order to do research properly, it is necessary to comprehend the rationale behind it. A research rationale is a succinct explanation of why a certain research project is required, describing the justifications for the study as well as the advantages it is expected to provide. 

Writing a persuasive rationale is critical for obtaining approval for your research project and communicating the importance of your research. However, developing a convincing one can be difficult, especially for people new to research or unfamiliar with academic expectations. 

After reading this thorough overview on “how to make rationale in research”, you will be better equipped to justify your research and communicate its significance to your academic community. Whether you are a student or a seasoned researcher, this article will provide valuable insights and strategies for creating a powerful research rationale.

What is a Rationale in Research?

A research rationale provides an organized strategy for the whole research and acts as the cornerstone of the research project. It contributes to the research’s rationale by stating why the study is significant, what its aims are, and what the expected findings are. In essence, it is a compelling argument for why the study should be carried out.

A well-written research rationale should be concise, precise, and persuasive. It should clarify the problem or issue that the study attempts to solve, the knowledge or understanding gap that the study seeks to fill, and the possible advantages that it may provide. Furthermore, the reasoning should demonstrate that the research is possible, ethical, and pertinent to the subject of study.

A research project that lacks a strong rationale may lack direction and may fail to address the stated problem or issue. It can also make obtaining financing or permission from institutional review boards (IRBs) or other governing bodies difficult. As a result, devoting effort to developing a compelling research rationale is critical to the success of any research.

Why is a Research Rationale Important? 

For many reasons, a research rationale is crucial. For starters, it helps to explain the necessity for the research project by demonstrating why the study is required and what gaps in knowledge or understanding it attempts to fill. 

Second, it includes a clear and succinct problem statement that outlines the precise research questions or objectives that the study intends to answer. 

Finally, it aids in demonstrating the research’s potential influence by demonstrating how it may lead to the creation of new knowledge, practices, or policies.

To achieve this, you should focus on communicating the potential benefits of your project, while also acknowledging its limitations. This requires a thorough understanding of the research problem and a critical evaluation of the proposed methods and approaches.

It is also important to include sufficient detail about the methods you plan to use, any ethical considerations to consider, and how you will evaluate your results. This helps to demonstrate that you have a well-developed and thoughtful research plan, which is essential for securing funding or gaining approval from academic institutions.

Consider an example of a research project to demonstrate this. Assume you want to investigate the effectiveness of a new teaching style in enhancing student learning results. A compelling rationale for this study might include:

  • Demonstrating the need for the study: You may explain that there is a rising concern in the educational environment about low student performance and that standard teaching approaches may not be helpful for all students. 
  • Providing a clear problem statement: For example, you might say that the study will look into whether the new teaching approach is effective at enhancing student learning outcomes and what factors may impact its effectiveness.
  • Highlighting the research’s potential impact: You might argue that if the study shows that if the new teaching approach is effective, it will be adopted in other schools, increasing student learning results.

The research rationale in this example gives a clear and compelling explanation for the necessity to perform the study, emphasizing its relevance, problem statement, and possible impact.

A Model: Problem-Solution-Rationale

The Problem-Solution-Rationale model is a helpful framework for developing a strong research rationale, it can assist you in organizing your rationale and ensuring that it clearly conveys all information required for an effective research rationale. This model consists of three major components: identifying the problem, proposing a solution, and explaining the rationale for why the proposed solution is necessary.

Identifying the Problem

The first stage in this model is to identify the problem that the study will attempt to solve. This could entail assessing existing research on the topic, finding gaps in knowledge or understanding, or emphasizing new difficulties or issues that have occurred. A clear problem statement serves as the research’s foundation, outlining the specific research questions or objectives that the study seeks to address.

Proposing a Solution

The model’s second stage is to suggest a solution to the identified problem. This might include creating a new theoretical framework, putting a new hypothesis to the test, or suggesting a new intervention or practice. The proposed solution should be based on a thorough review of the literature and a clear understanding of the research problem.

Providing a Rationale

The model’s final stage is to present a rationale for why the suggested solution is required. This might include emphasizing the possible advantages of the suggested solution, explaining how it builds on past research, or demonstrating how it fills a knowledge or understanding gap.

Language to Signal Rationale

Effective communication is crucial when it comes to justifying the significance of your research. One of the ways you can achieve this is by using specific language that signals the rationale to your intended audience. By doing so, you can clearly convey the reasons for your study and its potential benefits to your audience. Here are a couple of such examples:

  • “The goal of this research is to fill a knowledge gap on…”
  • “We selected this methodology because it allows us to address the research question more effectively.”
  • “Our approach is informed by the need to address the practical challenges of…”
  • “This research is significant because it contributes to our understanding of…”

Using statements like these can assist to convey the rationale to your audience and stress the significance of your research.

Language for Further Justification – Showing Importance

Once you’ve indicated the rationale for your research, it’s critical to give further justification that emphasizes the relevance of your study. Here are some sentences that might be used to emphasize the significance of your research:

  • “By addressing this gap in knowledge, we can gain a better understanding of…”
  • “This study is significant because it contributes to the development of…”
  • “The implications of this research are far-reaching, and it can inform…”
  • “By examining this issue, we can shed light on the broader implications of…”

How to Make Rationale In Research

Writing a compelling rationale for a research proposal is critical to obtaining funds and support for the research you are conducting. In this section, you will learn how to make rationale in research by implementing the four crucial aspects of a rationale: background on all previous research on the issue, the study’s open questions, identification of gaps in the literature, and the importance of filling these gaps.

Background on All Previous Research:

You must clarify the existing level of knowledge of the topic to offer a clear grasp of your research proposal. This entails analyzing all past research on the subject and determining what has been done previously. It is critical to present a thorough summary of existing research, including major results, hypotheses, and methodology. This can assist in demonstrating that you have a deep awareness of the field’s present state of knowledge and how your planned study might contribute to it.

The Study’s Open Questions

The next stage is to identify the study’s open questions. This entails investigating areas where existing knowledge falls short and comprehension gaps exist. You may highlight the need for more research and explain how your research will address these gaps by identifying unanswered questions.

Literature Gaps

Once you’ve discovered the open questions, describe how your research will solve them. This requires recognizing gaps in the current literature and describing how your research will address these gaps. Make it a point to explain how the proposed research differs from prior studies and how it will add to existing knowledge in the subject.

The Importance of Filling These Gaps:

Finally, it is critical to demonstrate the importance of filling these gaps in the current literature. This includes showing the possible advantages of the research and outlining how it will help the field if it can result in new ideas or new approaches, or the impact it will have on real society implications.

How to write the Rationale for your research

By charlesworth author services.

  • Charlesworth Author Services
  • 19 November, 2021

The rationale for one’s research is the justification for undertaking a given study. It states the reason(s) why a researcher chooses to focus on the topic in question, including what the significance is and what gaps the research intends to fill. In short, it is an explanation that rationalises the need for the study. The rationale is typically followed by a hypothesis/ research question (s) and the study objectives.

When is the rationale for research written?

The rationale of a study can be presented both before and after the research is conducted. 

  • Before : The rationale is a crucial part of your research proposal , representing the plan of your work as formulated before you execute your study.
  • After : Once the study is completed, the rationale is presented in a research paper or dissertation to explain why you focused on the particular question. In this instance, you would link the rationale of your research project to the study aims and outcomes.

Basis for writing the research rationale

The study rationale is predominantly based on preliminary data . A literature review will help you identify gaps in the current knowledge base and also ensure that you avoid duplicating what has already been done. You can then formulate the justification for your study from the existing literature on the subject and the perceived outcomes of the proposed study.

Length of the research rationale

In a research proposal or research article, the rationale would not take up more than a few sentences . A thesis or dissertation would allow for a longer description, which could even run into a couple of paragraphs . The length might even depend on the field of study or nature of the experiment. For instance, a completely novel or unconventional approach might warrant a longer and more detailed justification.

Basic elements of the research rationale

Every research rationale should include some mention or discussion of the following: 

  • An overview of your conclusions from your literature review
  • Gaps in current knowledge
  • Inconclusive or controversial findings from previous studies
  • The need to build on previous research (e.g. unanswered questions, the need to update concepts in light of new findings and/or new technical advancements). 

Example of a research rationale

Note: This uses a fictional study.

Abc xyz is a newly identified microalgal species isolated from fish tanks. While Abc xyz algal blooms have been seen as a threat to pisciculture, some studies have hinted at their unusually high carotenoid content and unique carotenoid profile. Carotenoid profiling has been carried out only in a handful of microalgal species from this genus, and the search for microalgae rich in bioactive carotenoids has not yielded promising candidates so far. This in-depth examination of the carotenoid profile of Abc xyz will help identify and quantify novel and potentially useful carotenoids from an untapped aquaculture resource .

In conclusion

It is important to describe the rationale of your research in order to put the significance and novelty of your specific research project into perspective. Once you have successfully articulated the reason(s) for your research, you will have convinced readers of the importance of your work!

Research-Methodology

Rationale for the Study

It is important for you to be able to explain the importance of the research you are conducting by providing valid arguments. Rationale for the study, also referred to as justification for the study, is reason why you have conducted your study in the first place. This part in your paper needs to explain uniqueness and importance of your research. Rationale for the study needs to be specific and ideally, it should relate to the following points:

1. The research needs to contribute to the elimination of a gap in the literature. Elimination of gap in the present literature is one of the compulsory requirements for your study. In other words, you don’t need to ‘re-invent the wheel’ and your research aims and objectives need to focus on new topics. For example, you can choose to conduct an empirical study to assess the implications of COVID-19 pandemic on the numbers of tourists visitors in your city. This might be previously undressed topic, taking into account that COVID-19 pandemic is a relatively recent phenomenon.

Alternatively, if you cannot find a new topic to research, you can attempt to offer fresh perspectives on existing management, business or economic issues. For example, while thousands of studies have been previously conducted to study various aspects of leadership, this topic as far from being exhausted as a research area. Specifically, new studies can be conducted in the area of leadership to analyze the impacts of new communication mediums such as TikTok, and other social networking sites on leadership practices.

You can also discuss the shortcomings of previous works devoted to your research area. Shortcomings in previous studies can be divided into three groups:

a) Methodological limitations . Methodology employed in previous study may be flawed in terms of research design, research approach or sampling.

b) Contextual limitations . Relevance of previous works may be non-existent for the present because external factors have changed.

c) Conceptual limitations . Previous studies may be unjustifiably bound up to a particular model or an ideology.

While discussing the shortcomings of previous studies you should explain how you are going to correct them. This principle is true to almost all areas in business studies i.e. gaps or shortcomings in the literature can be found in relation to almost all areas of business and economics.

2. The research can be conducted to solve a specific problem. It helps if you can explain why you are the right person and in the right position to solve the problem. You have to explain the essence of the problem in a detailed manner and highlight practical benefits associated with the solution of the problem. Suppose, your dissertation topic is “a study into advantages and disadvantages of various entry strategies into Chinese market”. In this case, you can say that practical implications of your research relates to assisting businesses aiming to enter Chinese market to do more informed decision making.

Alternatively, if your research is devoted to the analysis of impacts of CSR programs and initiatives on brand image, practical contributions of your study would relate to contributing to the level of effectiveness of CSR programs of businesses.

Additional examples of studies that can assist to address specific practical problems may include the following:

  • A study into the reasons of high employee turnover at Hanson Brick
  • A critical analysis of employee motivation problems at Esporta, Finchley Road, London
  • A research into effective succession planning at Microsoft
  • A study into major differences between private and public primary education in the USA and implications of these differences on the quality of education

However, it is important to note that it is not an obligatory for a dissertation   to be associated with the solution of a specific problem. Dissertations can be purely theory-based as well. Examples of such studies include the following:

  • Born or bred: revising The Great Man theory of leadership in the 21 st century
  • A critical analysis of the relevance of McClelland’s Achievement theory to the US information technology industry
  • Neoliberalism as a major reason behind the emergence of the global financial and economic crisis of 2007-2009
  • Analysis of Lewin’s Model of Change and its relevance to pharmaceutical sector of France

3. Your study has to contribute to the level of professional development of the researcher . That is you. You have to explain in a detailed manner in what ways your research contributes to the achievement of your long-term career aspirations.

For example, you have selected a research topic of “ A critical analysis of the relevance of McClelland’s Achievement theory in the US information technology industry ”.  You may state that you associate your career aspirations with becoming an IT executive in the US, and accordingly, in-depth knowledge of employee motivation in this industry is going to contribute your chances of success in your chosen career path.

Therefore, you are in a better position if you have already identified your career objectives, so that during the research process you can get detailed knowledge about various aspects of your chosen industry.

A study rationale explains the reason for a study and the importance of its findings for a particular field. Commonly, you'll need to write a study rationale as part of a university course of study, although you may also need to write one as a professional researcher to apply for funding or other support. As a student, your study rationale also justifies how it fulfills the requirements for your degree program or course of study. Do research before you write your study rationale so that you can discuss the previous work your study builds on and explain its significance to your field. Thorough research is also important in the professional context because your rationale will likely become part of the contract if funding or support is approved. [1] X Research source

Describing What You Hope to Accomplish

Step 1 Define the problem that your study will address.

  • For example, suppose you want to study how working the night shift affects the academic performance of college students who are taking classes during the day. A narrow question would measure a specific impact based on a specific amount of hours worked.

Step 2 Discuss the methodology for your study.

  • Justify the methodology you're using. If there's another methodology that might accomplish the same result, describe it and explain why your methodology is superior — perhaps because it's more efficient, takes less time, or uses fewer resources. For example, you might get more information out of personal interviews, but creating an online questionnaire is more cost-effective.
  • Particularly if you're seeking funding or support, this section of your rationale will also include details about the cost of your study and the facilities or resources you'll need. [3] X Research source

Tip: A methodology that is more complex, difficult, or expensive requires more justification than one that is straightforward and simple.

Step 3 Predict the results of your study.

  • For example, if you're studying the effect of working the night shift on academic performance, you might hypothesize that working 4 or more nights a week lowers students' grade point averages by more than 1 point.

Step 4 Explain what you hope your study will accomplish.

  • Use action words, such as "quantify" or "establish," when writing your goals. For example, you might write that one goal of your study is to "quantify the degree to which working at night inhibits the academic performance of college students."
  • If you are a professional researcher, your objectives may need to be more specific and concrete. The organization you submit your rationale to will have details about the requirements to apply for funding and other support. [5] X Research source

Explaining Your Study's Significance

Step 1 Discuss the previous work that your study will build on.

  • Going into extensive detail usually isn't necessary. Instead, highlight the findings of the most significant work in the field that addressed a similar question.
  • Provide references so that your readers can examine the previous studies for themselves and compare them to your proposed study.

Step 2 Describe the shortcomings of the previous work.

  • Methodological limitations: Previous studies failed to measure the variables appropriately or used a research design that had problems or biases
  • Contextual limitations: Previous studies aren't relevant because circumstances have changed regarding the variables measured
  • Conceptual limitations: Previous studies are too tied up in a specific ideology or framework

Step 3 Identify the ways your study will correct those shortcomings.

  • For example, if a previous study had been conducted to support a university's policy that full-time students were not permitted to work, you might argue that it was too tied up in that specific ideology and that this biased the results. You could then point out that your study is not intended to advance any particular policy.

Tip: If you have to defend or present your rationale to an advisor or team, try to anticipate the questions they might ask you and include the answers to as many of those questions as possible.

Including Academic Proposal Information

Step 1 Provide your credentials or experience as a student or researcher.

  • As a student, you might emphasize your major and specific classes you've taken that give you particular knowledge about the subject of your study. If you've served as a research assistant on a study with a similar methodology or covering a similar research question, you might mention that as well.
  • If you're a professional researcher, focus on the experience you have in a particular field as well as the studies you've done in the past. If you have done studies with a similar methodology that were important in your field, you might mention those as well.

Tip: If you don't have any particular credentials or experience that are relevant to your study, tell the readers of your rationale what drew you to this particular topic and how you became interested in it.

Step 2 State any guidelines required by your degree program or field.

  • For example, if you are planning to conduct the study as fulfillment of the research requirement for your degree program, you might discuss any specific guidelines for that research requirement and list how your study meets those criteria.

Step 3 List the credits you intend your study to fulfill.

  • In most programs, there will be specific wording for you to include in your rationale if you're submitting it for a certain number of credits. Your instructor or advisor can help make sure you've worded this appropriately.

Quantitative methods emphasize objective measurements and the statistical, mathematical, or numerical analysis of data collected through polls, questionnaires, and surveys, or by manipulating pre-existing statistical data using computational techniques . Quantitative research focuses on gathering numerical data and generalizing it across groups of people or to explain a particular phenomenon.

Characteristics of Quantitative Research

Your goal in conducting quantitative research study is to determine the relationship between one thing [an independent variable] and another [a dependent or outcome variable] within a population. Quantitative research designs are either descriptive [subjects usually measured once] or experimental [subjects measured before and after a treatment]. A descriptive study establishes only associations between variables; an experimental study establishes causality.

Quantitative research deals in numbers, logic, and an objective stance. Quantitative research focuses on numeric and unchanging data and detailed, convergent reasoning rather than divergent reasoning [i.e., the generation of a variety of ideas about a research problem in a spontaneous, free-flowing manner].

Its main characteristics are :

  • The data is usually gathered using structured research instruments.
  • The results are based on larger sample sizes that are representative of the population.
  • The research study can usually be replicated or repeated, given its high reliability.
  • Researcher has a clearly defined research question to which objective answers are sought.
  • All aspects of the study are carefully designed before data is collected.
  • Data are in the form of numbers and statistics, often arranged in tables, charts, figures, or other non-textual forms.
  • Project can be used to generalize concepts more widely, predict future results, or investigate causal relationships.
  • Researcher uses tools, such as questionnaires or computer software, to collect numerical data.

The overarching aim of a quantitative research study is to classify features, count them, and construct statistical models in an attempt to explain what is observed.

  Things to keep in mind when reporting the results of a study using quantitative methods :

  • Explain the data collected and their statistical treatment as well as all relevant results in relation to the research problem you are investigating. Interpretation of results is not appropriate in this section.
  • Report unanticipated events that occurred during your data collection. Explain how the actual analysis differs from the planned analysis. Explain your handling of missing data and why any missing data does not undermine the validity of your analysis.
  • Explain the techniques you used to "clean" your data set.
  • Choose a minimally sufficient statistical procedure ; provide a rationale for its use and a reference for it. Specify any computer programs used.
  • Describe the assumptions for each procedure and the steps you took to ensure that they were not violated.
  • When using inferential statistics , provide the descriptive statistics, confidence intervals, and sample sizes for each variable as well as the value of the test statistic, its direction, the degrees of freedom, and the significance level [report the actual p value].
  • Avoid inferring causality , particularly in nonrandomized designs or without further experimentation.
  • Use tables to provide exact values ; use figures to convey global effects. Keep figures small in size; include graphic representations of confidence intervals whenever possible.
  • Always tell the reader what to look for in tables and figures .

NOTE:   When using pre-existing statistical data gathered and made available by anyone other than yourself [e.g., government agency], you still must report on the methods that were used to gather the data and describe any missing data that exists and, if there is any, provide a clear explanation why the missing data does not undermine the validity of your final analysis.

Basic Research Design for Quantitative Studies

Before designing a quantitative research study, you must decide whether it will be descriptive or experimental because this will dictate how you gather, analyze, and interpret the results. A descriptive study is governed by the following rules: subjects are generally measured once; the intention is to only establish associations between variables; and, the study may include a sample population of hundreds or thousands of subjects to ensure that a valid estimate of a generalized relationship between variables has been obtained. An experimental design includes subjects measured before and after a particular treatment, the sample population may be very small and purposefully chosen, and it is intended to establish causality between variables. Introduction The introduction to a quantitative study is usually written in the present tense and from the third person point of view. It covers the following information:

  • Identifies the research problem -- as with any academic study, you must state clearly and concisely the research problem being investigated.
  • Reviews the literature -- review scholarship on the topic, synthesizing key themes and, if necessary, noting studies that have used similar methods of inquiry and analysis. Note where key gaps exist and how your study helps to fill these gaps or clarifies existing knowledge.
  • Describes the theoretical framework -- provide an outline of the theory or hypothesis underpinning your study. If necessary, define unfamiliar or complex terms, concepts, or ideas and provide the appropriate background information to place the research problem in proper context [e.g., historical, cultural, economic, etc.].

Methodology The methods section of a quantitative study should describe how each objective of your study will be achieved. Be sure to provide enough detail to enable the reader can make an informed assessment of the methods being used to obtain results associated with the research problem. The methods section should be presented in the past tense.

  • Study population and sampling -- where did the data come from; how robust is it; note where gaps exist or what was excluded. Note the procedures used for their selection;
  • Data collection – describe the tools and methods used to collect information and identify the variables being measured; describe the methods used to obtain the data; and, note if the data was pre-existing [i.e., government data] or you gathered it yourself. If you gathered it yourself, describe what type of instrument you used and why. Note that no data set is perfect--describe any limitations in methods of gathering data.
  • Data analysis -- describe the procedures for processing and analyzing the data. If appropriate, describe the specific instruments of analysis used to study each research objective, including mathematical techniques and the type of computer software used to manipulate the data.

Results The finding of your study should be written objectively and in a succinct and precise format. In quantitative studies, it is common to use graphs, tables, charts, and other non-textual elements to help the reader understand the data. Make sure that non-textual elements do not stand in isolation from the text but are being used to supplement the overall description of the results and to help clarify key points being made. Further information about how to effectively present data using charts and graphs can be found here .

  • Statistical analysis -- how did you analyze the data? What were the key findings from the data? The findings should be present in a logical, sequential order. Describe but do not interpret these trends or negative results; save that for the discussion section. The results should be presented in the past tense.

Discussion Discussions should be analytic, logical, and comprehensive. The discussion should meld together your findings in relation to those identified in the literature review, and placed within the context of the theoretical framework underpinning the study. The discussion should be presented in the present tense.

  • Interpretation of results -- reiterate the research problem being investigated and compare and contrast the findings with the research questions underlying the study. Did they affirm predicted outcomes or did the data refute it?
  • Description of trends, comparison of groups, or relationships among variables -- describe any trends that emerged from your analysis and explain all unanticipated and statistical insignificant findings.
  • Discussion of implications – what is the meaning of your results? Highlight key findings based on the overall results and note findings that you believe are important. How have the results helped fill gaps in understanding the research problem?
  • Limitations -- describe any limitations or unavoidable bias in your study and, if necessary, note why these limitations did not inhibit effective interpretation of the results.

Conclusion End your study by to summarizing the topic and provide a final comment and assessment of the study.

  • Summary of findings – synthesize the answers to your research questions. Do not report any statistical data here; just provide a narrative summary of the key findings and describe what was learned that you did not know before conducting the study.
  • Recommendations – if appropriate to the aim of the assignment, tie key findings with policy recommendations or actions to be taken in practice.
  • Future research – note the need for future research linked to your study’s limitations or to any remaining gaps in the literature that were not addressed in your study.

Strengths of Using Quantitative Methods

Quantitative researchers try to recognize and isolate specific variables contained within the study framework, seek correlation, relationships and causality, and attempt to control the environment in which the data is collected to avoid the risk of variables, other than the one being studied, accounting for the relationships identified.

Among the specific strengths of using quantitative methods to study social science research problems:

  • Allows for a broader study, involving a greater number of subjects, and enhancing the generalization of the results;
  • Allows for greater objectivity and accuracy of results. Generally, quantitative methods are designed to provide summaries of data that support generalizations about the phenomenon under study. In order to accomplish this, quantitative research usually involves few variables and many cases, and employs prescribed procedures to ensure validity and reliability;
  • Applying well established standards means that the research can be replicated, and then analyzed and compared with similar studies;
  • You can summarize vast sources of information and make comparisons across categories and over time; and,
  • Personal bias can be avoided by keeping a 'distance' from participating subjects and using accepted computational techniques .

Quantitative Social Research Methods . Los Angeles, CA: Sage, 2007.

Limitations of Using Quantitative Methods

Quantitative methods presume to have an objective approach to studying research problems, where data is controlled and measured, to address the accumulation of facts, and to determine the causes of behavior. As a consequence, the results of quantitative research may be statistically significant but are often humanly insignificant.

Some specific limitations associated with using quantitative methods to study research problems in the social sciences include:

  • Quantitative data is more efficient and able to test hypotheses, but may miss contextual detail;
  • Uses a static and rigid approach and so employs an inflexible process of discovery;
  • The development of standard questions by researchers can lead to "structural bias" and false representation, where the data actually reflects the view of the researcher instead of the participating subject;
  • Results provide less detail on behavior, attitudes, and motivation;
  • Researcher may collect a much narrower and sometimes superficial dataset;
  • Results are limited as they provide numerical descriptions rather than detailed narrative and generally provide less elaborate accounts of human perception;
  • The research is often carried out in an unnatural, artificial environment so that a level of control can be applied to the exercise. This level of control might not normally be in place in the real world thus yielding "laboratory results" as opposed to "real world results"; and,
  • Preset answers will not necessarily reflect how people really feel about a subject and, in some cases, might just be the closest match to the preconceived hypothesis.

What Is Quantitative Research? | Definition, Uses & Methods

Published on June 12, 2020 by Pritha Bhandari . Revised on June 22, 2023.

Quantitative research is the process of collecting and analyzing numerical data. It can be used to find patterns and averages, make predictions, test causal relationships, and generalize results to wider populations.

Quantitative research is the opposite of qualitative research , which involves collecting and analyzing non-numerical data (e.g., text, video, or audio).

Quantitative research is widely used in the natural and social sciences: biology, chemistry, psychology, economics, sociology, marketing, etc.

  • What is the demographic makeup of Singapore in 2020?
  • How has the average temperature changed globally over the last century?
  • Does environmental pollution affect the prevalence of honey bees?
  • Does working from home increase productivity for people with long commutes?

You can use quantitative research methods for descriptive, correlational or experimental research.

  • In descriptive research , you simply seek an overall summary of your study variables.
  • In correlational research , you investigate relationships between your study variables.
  • In experimental research , you systematically examine whether there is a cause-and-effect relationship between variables.

Correlational and experimental research can both be used to formally test hypotheses , or predictions, using statistics. The results may be generalized to broader populations based on the sampling method used.

To collect quantitative data, you will often need to use operational definitions that translate abstract concepts (e.g., mood) into observable and quantifiable measures (e.g., self-ratings of feelings and energy levels).

Quantitative research methods
Research method How to use Example
Control or manipulate an to measure its effect on a dependent variable. To test whether an intervention can reduce procrastination in college students, you give equal-sized groups either a procrastination intervention or a comparable task. You compare self-ratings of procrastination behaviors between the groups after the intervention.
Ask questions of a group of people in-person, over-the-phone or online. You distribute with rating scales to first-year international college students to investigate their experiences of culture shock.
(Systematic) observation Identify a behavior or occurrence of interest and monitor it in its natural setting. To study college classroom participation, you sit in on classes to observe them, counting and recording the prevalence of active and passive behaviors by students from different backgrounds.
Secondary research Collect data that has been gathered for other purposes e.g., national surveys or historical records. To assess whether attitudes towards climate change have changed since the 1980s, you collect relevant questionnaire data from widely available .

Note that quantitative research is at risk for certain research biases , including information bias , omitted variable bias , sampling bias , or selection bias . Be sure that you’re aware of potential biases as you collect and analyze your data to prevent them from impacting your work too much.

Once data is collected, you may need to process it before it can be analyzed. For example, survey and test data may need to be transformed from words to numbers. Then, you can use statistical analysis to answer your research questions .

Descriptive statistics will give you a summary of your data and include measures of averages and variability. You can also use graphs, scatter plots and frequency tables to visualize your data and check for any trends or outliers.

Using inferential statistics , you can make predictions or generalizations based on your data. You can test your hypothesis or use your sample data to estimate the population parameter .

First, you use descriptive statistics to get a summary of the data. You find the mean (average) and the mode (most frequent rating) of procrastination of the two groups, and plot the data to see if there are any outliers.

You can also assess the reliability and validity of your data collection methods to indicate how consistently and accurately your methods actually measured what you wanted them to.

Quantitative research is often used to standardize data collection and generalize findings . Strengths of this approach include:

  • Replication

Repeating the study is possible because of standardized data collection protocols and tangible definitions of abstract concepts.

  • Direct comparisons of results

The study can be reproduced in other cultural settings, times or with different groups of participants. Results can be compared statistically.

  • Large samples

Data from large samples can be processed and analyzed using reliable and consistent procedures through quantitative data analysis.

  • Hypothesis testing

Using formalized and established hypothesis testing procedures means that you have to carefully consider and report your research variables, predictions, data collection and testing methods before coming to a conclusion.

Despite the benefits of quantitative research, it is sometimes inadequate in explaining complex research topics. Its limitations include:

  • Superficiality

Using precise and restrictive operational definitions may inadequately represent complex concepts. For example, the concept of mood may be represented with just a number in quantitative research, but explained with elaboration in qualitative research.

  • Narrow focus

Predetermined variables and measurement procedures can mean that you ignore other relevant observations.

  • Structural bias

Despite standardized procedures, structural biases can still affect quantitative research. Missing data , imprecise measurements or inappropriate sampling methods are biases that can lead to the wrong conclusions.

  • Lack of context

Quantitative research often uses unnatural settings like laboratories or fails to consider historical and cultural contexts that may affect data collection and results.

Research bias

  • Rosenthal effect
  • Implicit bias
  • Cognitive bias
  • Selection bias
  • Negativity bias
  • Status quo bias

Quantitative research deals with numbers and statistics, while qualitative research deals with words and meanings.

Quantitative methods allow you to systematically measure variables and test hypotheses . Qualitative methods allow you to explore concepts and experiences in more detail.

In mixed methods research , you use both qualitative and quantitative data collection and analysis methods to answer your research question .

Data collection is the systematic process by which observations or measurements are gathered in research. It is used in many different contexts by academics, governments, businesses, and other organizations.

Operationalization means turning abstract conceptual ideas into measurable observations.

For example, the concept of social anxiety isn’t directly observable, but it can be operationally defined in terms of self-rating scores, behavioral avoidance of crowded places, or physical anxiety symptoms in social situations.

Before collecting data , it’s important to consider how you will operationalize the variables that you want to measure.

Reliability and validity are both about how well a method measures something:

  • Reliability refers to the  consistency of a measure (whether the results can be reproduced under the same conditions).
  • Validity   refers to the  accuracy of a measure (whether the results really do represent what they are supposed to measure).

If you are doing experimental research, you also have to consider the internal and external validity of your experiment.

Hypothesis testing is a formal procedure for investigating our ideas about the world using statistics. It is used by scientists to test specific predictions, called hypotheses , by calculating how likely it is that a pattern or relationship between variables could have arisen by chance.

Introduction

Some nurses feel that they lack the necessary skills to read a research paper and to then decide if they should implement the findings into their practice. This is particularly the case when considering the results of quantitative research, which often contains the results of statistical testing. However, nurses have a professional responsibility to critique research to improve their practice, care and patient safety. 1  This article provides a step by step guide on how to critically appraise a quantitative paper.

Title, keywords and the authors

The authors’ names may not mean much, but knowing the following will be helpful:

Their position, for example, academic, researcher or healthcare practitioner.

Their qualification, both professional, for example, a nurse or physiotherapist and academic (eg, degree, masters, doctorate).

This can indicate how the research has been conducted and the authors’ competence on the subject. Basically, do you want to read a paper on quantum physics written by a plumber?

The abstract is a resume of the article and should contain:

Introduction.

Research question/hypothesis.

Methods including sample design, tests used and the statistical analysis (of course! Remember we love numbers).

Main findings.

Conclusion.

The subheadings in the abstract will vary depending on the journal. An abstract should not usually be more than 300 words but this varies depending on specific journal requirements. If the above information is contained in the abstract, it can give you an idea about whether the study is relevant to your area of practice. However, before deciding if the results of a research paper are relevant to your practice, it is important to review the overall quality of the article. This can only be done by reading and critically appraising the entire article.

The introduction

Example: the effect of paracetamol on levels of pain.

My hypothesis is that A has an effect on B, for example, paracetamol has an effect on levels of pain.

My null hypothesis is that A has no effect on B, for example, paracetamol has no effect on pain.

My study will test the null hypothesis and if the null hypothesis is validated then the hypothesis is false (A has no effect on B). This means paracetamol has no effect on the level of pain. If the null hypothesis is rejected then the hypothesis is true (A has an effect on B). This means that paracetamol has an effect on the level of pain.

Background/literature review

The literature review should include reference to recent and relevant research in the area. It should summarise what is already known about the topic and why the research study is needed and state what the study will contribute to new knowledge. 5 The literature review should be up to date, usually 5–8 years, but it will depend on the topic and sometimes it is acceptable to include older (seminal) studies.

Methodology

In quantitative studies, the data analysis varies between studies depending on the type of design used. For example, descriptive, correlative or experimental studies all vary. A descriptive study will describe the pattern of a topic related to one or more variable. 6 A correlational study examines the link (correlation) between two variables 7  and focuses on how a variable will react to a change of another variable. In experimental studies, the researchers manipulate variables looking at outcomes 8  and the sample is commonly assigned into different groups (known as randomisation) to determine the effect (causal) of a condition (independent variable) on a certain outcome. This is a common method used in clinical trials.

There should be sufficient detail provided in the methods section for you to replicate the study (should you want to). To enable you to do this, the following sections are normally included:

Overview and rationale for the methodology.

Participants or sample.

Data collection tools.

Methods of data analysis.

Ethical issues.

Data collection should be clearly explained and the article should discuss how this process was undertaken. Data collection should be systematic, objective, precise, repeatable, valid and reliable. Any tool (eg, a questionnaire) used for data collection should have been piloted (or pretested and/or adjusted) to ensure the quality, validity and reliability of the tool. 9 The participants (the sample) and any randomisation technique used should be identified. The sample size is central in quantitative research, as the findings should be able to be generalised for the wider population. 10 The data analysis can be done manually or more complex analyses performed using computer software sometimes with advice of a statistician. From this analysis, results like mode, mean, median, p value, CI and so on are always presented in a numerical format.

The author(s) should present the results clearly. These may be presented in graphs, charts or tables alongside some text. You should perform your own critique of the data analysis process; just because a paper has been published, it does not mean it is perfect. Your findings may be different from the author’s. Through critical analysis the reader may find an error in the study process that authors have not seen or highlighted. These errors can change the study result or change a study you thought was strong to weak. To help you critique a quantitative research paper, some guidance on understanding statistical terminology is provided in  table 1 .

  • View inline

Some basic guidance for understanding statistics

Quantitative studies examine the relationship between variables, and the p value illustrates this objectively.  11  If the p value is less than 0.05, the null hypothesis is rejected and the hypothesis is accepted and the study will say there is a significant difference. If the p value is more than 0.05, the null hypothesis is accepted then the hypothesis is rejected. The study will say there is no significant difference. As a general rule, a p value of less than 0.05 means, the hypothesis is accepted and if it is more than 0.05 the hypothesis is rejected.

The CI is a number between 0 and 1 or is written as a per cent, demonstrating the level of confidence the reader can have in the result. 12  The CI is calculated by subtracting the p value to 1 (1–p). If there is a p value of 0.05, the CI will be 1–0.05=0.95=95%. A CI over 95% means, we can be confident the result is statistically significant. A CI below 95% means, the result is not statistically significant. The p values and CI highlight the confidence and robustness of a result.

Discussion, recommendations and conclusion

The final section of the paper is where the authors discuss their results and link them to other literature in the area (some of which may have been included in the literature review at the start of the paper). This reminds the reader of what is already known, what the study has found and what new information it adds. The discussion should demonstrate how the authors interpreted their results and how they contribute to new knowledge in the area. Implications for practice and future research should also be highlighted in this section of the paper.

A few other areas you may find helpful are:

Limitations of the study.

Conflicts of interest.

Table 2 provides a useful tool to help you apply the learning in this paper to the critiquing of quantitative research papers.

How To Choose Your Research Methodology

Qualitative vs quantitative vs mixed methods.

By: Derek Jansen (MBA). Expert Reviewed By: Dr Eunice Rautenbach | June 2021

Without a doubt, one of the most common questions we receive at Grad Coach is “ How do I choose the right methodology for my research? ”. It’s easy to see why – with so many options on the research design table, it’s easy to get intimidated, especially with all the complex lingo!

In this post, we’ll explain the three overarching types of research – qualitative, quantitative and mixed methods – and how you can go about choosing the best methodological approach for your research.

1. Understanding the options

Before we jump into the question of how to choose a research methodology, it’s useful to take a step back to understand the three overarching types of research – qualitative , quantitative and mixed methods -based research. Each of these options takes a different methodological approach.

Qualitative research utilises data that is not numbers-based. In other words, qualitative research focuses on words , descriptions , concepts or ideas – while quantitative research makes use of numbers and statistics. Qualitative research investigates the “softer side” of things to explore and describe, while quantitative research focuses on the “hard numbers”, to measure differences between variables and the relationships between them.

Importantly, qualitative research methods are typically used to explore and gain a deeper understanding of the complexity of a situation – to draw a rich picture . In contrast to this, quantitative methods are usually used to confirm or test hypotheses . In other words, they have distinctly different purposes. The table below highlights a few of the key differences between qualitative and quantitative research – you can learn more about the differences here.

  • Uses an inductive approach
  • Is used to build theories
  • Takes a subjective approach
  • Adopts an open and flexible approach
  • The researcher is close to the respondents
  • Interviews and focus groups are oftentimes used to collect word-based data.
  • Generally, draws on small sample sizes
  • Uses qualitative data analysis techniques (e.g. content analysis , thematic analysis , etc)
  • Uses a deductive approach
  • Is used to test theories
  • Takes an objective approach
  • Adopts a closed, highly planned approach
  • The research is disconnected from respondents
  • Surveys or laboratory equipment are often used to collect number-based data.
  • Generally, requires large sample sizes
  • Uses statistical analysis techniques to make sense of the data

Mixed methods -based research, as you’d expect, attempts to bring these two types of research together, drawing on both qualitative and quantitative data. Quite often, mixed methods-based studies will use qualitative research to explore a situation and develop a potential model of understanding (this is called a conceptual framework), and then go on to use quantitative methods to test that model empirically.

In other words, while qualitative and quantitative methods (and the philosophies that underpin them) are completely different, they are not at odds with each other. It’s not a competition of qualitative vs quantitative. On the contrary, they can be used together to develop a high-quality piece of research. Of course, this is easier said than done, so we usually recommend that first-time researchers stick to a single approach , unless the nature of their study truly warrants a mixed-methods approach.

The key takeaway here, and the reason we started by looking at the three options, is that it’s important to understand that each methodological approach has a different purpose – for example, to explore and understand situations (qualitative), to test and measure (quantitative) or to do both. They’re not simply alternative tools for the same job. 

Right – now that we’ve got that out of the way, let’s look at how you can go about choosing the right methodology for your research.

Methodology choices in research

2. How to choose a research methodology

To choose the right research methodology for your dissertation or thesis, you need to consider three important factors . Based on these three factors, you can decide on your overarching approach – qualitative, quantitative or mixed methods. Once you’ve made that decision, you can flesh out the finer details of your methodology, such as the sampling , data collection methods and analysis techniques (we discuss these separately in other posts ).

The three factors you need to consider are:

  • The nature of your research aims, objectives and research questions
  • The methodological approaches taken in the existing literature
  • Practicalities and constraints

Let’s take a look at each of these.

Factor #1: The nature of your research

As I mentioned earlier, each type of research (and therefore, research methodology), whether qualitative, quantitative or mixed, has a different purpose and helps solve a different type of question. So, it’s logical that the key deciding factor in terms of which research methodology you adopt is the nature of your research aims, objectives and research questions .

But, what types of research exist?

Broadly speaking, research can fall into one of three categories:

  • Exploratory – getting a better understanding of an issue and potentially developing a theory regarding it
  • Confirmatory – confirming a potential theory or hypothesis by testing it empirically
  • A mix of both – building a potential theory or hypothesis and then testing it

As a rule of thumb, exploratory research tends to adopt a qualitative approach , whereas confirmatory research tends to use quantitative methods . This isn’t set in stone, but it’s a very useful heuristic. Naturally then, research that combines a mix of both, or is seeking to develop a theory from the ground up and then test that theory, would utilize a mixed-methods approach.

Exploratory vs confirmatory research

Let’s look at an example in action.

If your research aims were to understand the perspectives of war veterans regarding certain political matters, you’d likely adopt a qualitative methodology, making use of interviews to collect data and one or more qualitative data analysis methods to make sense of the data.

If, on the other hand, your research aims involved testing a set of hypotheses regarding the link between political leaning and income levels, you’d likely adopt a quantitative methodology, using numbers-based data from a survey to measure the links between variables and/or constructs .

So, the first (and most important thing) thing you need to consider when deciding which methodological approach to use for your research project is the nature of your research aims , objectives and research questions. Specifically, you need to assess whether your research leans in an exploratory or confirmatory direction or involves a mix of both.

The importance of achieving solid alignment between these three factors and your methodology can’t be overstated. If they’re misaligned, you’re going to be forcing a square peg into a round hole. In other words, you’ll be using the wrong tool for the job, and your research will become a disjointed mess.

If your research is a mix of both exploratory and confirmatory, but you have a tight word count limit, you may need to consider trimming down the scope a little and focusing on one or the other. One methodology executed well has a far better chance of earning marks than a poorly executed mixed methods approach. So, don’t try to be a hero, unless there is a very strong underpinning logic.

how to make a rationale in quantitative research

Factor #2: The disciplinary norms

Choosing the right methodology for your research also involves looking at the approaches used by other researchers in the field, and studies with similar research aims and objectives to yours. Oftentimes, within a discipline, there is a common methodological approach (or set of approaches) used in studies. While this doesn’t mean you should follow the herd “just because”, you should at least consider these approaches and evaluate their merit within your context.

A major benefit of reviewing the research methodologies used by similar studies in your field is that you can often piggyback on the data collection techniques that other (more experienced) researchers have developed. For example, if you’re undertaking a quantitative study, you can often find tried and tested survey scales with high Cronbach’s alphas. These are usually included in the appendices of journal articles, so you don’t even have to contact the original authors. By using these, you’ll save a lot of time and ensure that your study stands on the proverbial “shoulders of giants” by using high-quality measurement instruments .

Of course, when reviewing existing literature, keep point #1 front of mind. In other words, your methodology needs to align with your research aims, objectives and questions. Don’t fall into the trap of adopting the methodological “norm” of other studies just because it’s popular. Only adopt that which is relevant to your research.

Factor #3: Practicalities

When choosing a research methodology, there will always be a tension between doing what’s theoretically best (i.e., the most scientifically rigorous research design ) and doing what’s practical , given your constraints . This is the nature of doing research and there are always trade-offs, as with anything else.

But what constraints, you ask?

When you’re evaluating your methodological options, you need to consider the following constraints:

  • Data access
  • Equipment and software
  • Your knowledge and skills

Let’s look at each of these.

Constraint #1: Data access

The first practical constraint you need to consider is your access to data . If you’re going to be undertaking primary research , you need to think critically about the sample of respondents you realistically have access to. For example, if you plan to use in-person interviews , you need to ask yourself how many people you’ll need to interview, whether they’ll be agreeable to being interviewed, where they’re located, and so on.

If you’re wanting to undertake a quantitative approach using surveys to collect data, you’ll need to consider how many responses you’ll require to achieve statistically significant results. For many statistical tests, a sample of a few hundred respondents is typically needed to develop convincing conclusions.

So, think carefully about what data you’ll need access to, how much data you’ll need and how you’ll collect it. The last thing you want is to spend a huge amount of time on your research only to find that you can’t get access to the required data.

Constraint #2: Time

The next constraint is time. If you’re undertaking research as part of a PhD, you may have a fairly open-ended time limit, but this is unlikely to be the case for undergrad and Masters-level projects. So, pay attention to your timeline, as the data collection and analysis components of different methodologies have a major impact on time requirements . Also, keep in mind that these stages of the research often take a lot longer than originally anticipated.

Another practical implication of time limits is that it will directly impact which time horizon you can use – i.e. longitudinal vs cross-sectional . For example, if you’ve got a 6-month limit for your entire research project, it’s quite unlikely that you’ll be able to adopt a longitudinal time horizon. 

Constraint #3: Money

As with so many things, money is another important constraint you’ll need to consider when deciding on your research methodology. While some research designs will cost near zero to execute, others may require a substantial budget .

Some of the costs that may arise include:

  • Software costs – e.g. survey hosting services, analysis software, etc.
  • Promotion costs – e.g. advertising a survey to attract respondents
  • Incentive costs – e.g. providing a prize or cash payment incentive to attract respondents
  • Equipment rental costs – e.g. recording equipment, lab equipment, etc.
  • Travel costs
  • Food & beverages

These are just a handful of costs that can creep into your research budget. Like most projects, the actual costs tend to be higher than the estimates, so be sure to err on the conservative side and expect the unexpected. It’s critically important that you’re honest with yourself about these costs, or you could end up getting stuck midway through your project because you’ve run out of money.

Budgeting for your research

Constraint #4: Equipment & software

Another practical consideration is the hardware and/or software you’ll need in order to undertake your research. Of course, this variable will depend on the type of data you’re collecting and analysing. For example, you may need lab equipment to analyse substances, or you may need specific analysis software to analyse statistical data. So, be sure to think about what hardware and/or software you’ll need for each potential methodological approach, and whether you have access to these.

Constraint #5: Your knowledge and skillset

The final practical constraint is a big one. Naturally, the research process involves a lot of learning and development along the way, so you will accrue knowledge and skills as you progress. However, when considering your methodological options, you should still consider your current position on the ladder.

Some of the questions you should ask yourself are:

  • Am I more of a “numbers person” or a “words person”?
  • How much do I know about the analysis methods I’ll potentially use (e.g. statistical analysis)?
  • How much do I know about the software and/or hardware that I’ll potentially use?
  • How excited am I to learn new research skills and gain new knowledge?
  • How much time do I have to learn the things I need to learn?

Answering these questions honestly will provide you with another set of criteria against which you can evaluate the research methodology options you’ve shortlisted.

So, as you can see, there is a wide range of practicalities and constraints that you need to take into account when you’re deciding on a research methodology. These practicalities create a tension between the “ideal” methodology and the methodology that you can realistically pull off. This is perfectly normal, and it’s your job to find the option that presents the best set of trade-offs.

Recap: Choosing a methodology

In this post, we’ve discussed how to go about choosing a research methodology. The three major deciding factors we looked at were:

  • Exploratory
  • Confirmatory
  • Combination
  • Research area norms
  • Hardware and software
  • Your knowledge and skillset

Metrics details

Despite the central role of mixed methods in health research, studies evaluating online methods training in the health sciences are nonexistent. The focused goal was to evaluate online training by comparing the self-rated skills of scholars who experienced an in-person retreat to scholars in an online retreat in specific domains of mixed methods research for the health sciences from 2015–2023.

The authors administered a scholar Mixed Methods Skills Self-Assessment instrument based on an educational competency scale that included domains on: “research questions,” “design/approach,” “sampling,” “analysis,” and “dissemination” to participants of the Mixed Methods Research Training Program for the Health Sciences (MMRTP). Self-ratings on confidence on domains were compared before and after retreat participation within cohorts who attended in person ( n  = 73) or online ( n  = 57) as well as comparing across in-person to online cohorts. Responses to open-ended questions about experiences with the retreat were analyzed.

Scholars in an interactive program to improve mixed methods skills reported significantly increased confidence in ability to define or explain concepts and in ability to apply the concepts to practical problems, whether the program was attended in-person or synchronously online. Scholars in the online retreat had self-rated skill improvements as good or better than scholars who participated in person. With the possible exception of networking, scholars found the online format was associated with advantages such as accessibility and reduced burden of travel and finding childcare. No differences in difficulty of learning concepts was described.

Conclusions

Keeping in mind that the retreat is only one component of the MMRTP, this study provides evidence that mixed methods training online was associated with the same increases in self-rated skills as persons attending online and can be a key component to increasing the capacity for mixed methods research in the health sciences.

Peer Review reports

Introduction

The coronavirus pandemic accelerated interest in distance or remote learning. While the acute nature of the pandemic has abated, changes in the way people work have largely remained, with hybrid conferences and trainings more commonly implemented now than during the pre-pandemic period. Studies of health-related online teaching have focused on medical students [ 1 , 2 , 3 ], health professionals [ 4 , 5 ], and medical conferences [ 6 , 7 , 8 ] and have touted the advantages of virtual training and conferences in health education, but few studies have assessed relative growth in skills and competencies in health research methods for synchronous online vs. in-person training.

The National Institutes of Health (NIH)-funded Mixed Methods Research Training Program (MMRTP) for the Health Sciences provided training to faculty-level investigators across health disciplines from 2015–2023. The NIH is a major funder of health-related research in the United States. Its institutes span diseases and conditions (e.g., mental health, environmental health) in addition to focus areas (e.g., minority health and health disparities, nursing) and developing research capacity. Scholars in the MMRTP seek to develop skills in mixed methods research through participation in a summer retreat followed by ongoing mentorship for one year from a mixed methods expert matched to the scholar to support their development of a research proposal. Webinars leading up to the retreat include didactic sessions taught by the same faculty each year, and the retreat itself contains multiple interactive small group sessions in which each scholar presents their project and receives feedback on their grant proposal. Due to pandemic restrictions on gatherings and travel, in 2020 the MMRTP retained all components of the program but transitioned the in-person retreat to a synchronous online retreat.

The number of NIH agencies funding mixed methods research increased from 23 in 1997–2008 to 36 in 2009–2014 [ 9 ]. The usefulness of mixed methods research aligns with several Institutes’ strategic priories, including improving health equity, enhancing feasibility, acceptability, and sustainability of interventions, and addressing patient-centeredness. However, there is a tension between growing interest in mixed methods for health sciences research and a lack of training for investigators to acquire mixed methods research skills. Mixed methods research is not routinely taught in doctoral programs, institutional grant-writing programs, nor research training that academic physicians receive. The relative lack of researchers trained in mixed methods research necessitates ongoing research capacity building and mentorship [ 10 ]. Online teaching has the potential to meet growing demand for training and mentoring in mixed methods, as evidenced by the growth of online offerings by the Mixed Methods International Research Association [ 11 ]. Yet, the nature of skills and attitudes required for doing mixed methods research, such as integration of quantitative and qualitative data collection, analysis, and epistemologies, may make this type of training difficult to adapt to an online format without compromising its effectiveness.

Few studies have attempted to evaluate mixed methods training [ 12 , 13 , 14 , 15 ] and none appear to have evaluated online trainings in mixed methods research. Our goal was to evaluate our online MMRTP by comparing the self-rated skills of scholars who experienced an in-person retreat to an online retreat across specific domains. While the MMRTP retreat is only one component of the program, assessment before and after the retreat among persons who experienced the synchronous retreat online compared to in-person provides an indication of the effectiveness of online instruction in mixed methods for specific domains critical to the design of research in health services. We hypothesized that scholars who attended the retreat online would exhibit improvements in self-rated skills comparable to scholars who attended in person.

Participants

Five cohorts with a total of 73 scholars participated in the MMRTP in person (2015–2019), while four cohorts with a total of 57 scholars participated online (2020–2023). Scholars are faculty-level researchers in the health sciences in the United States. The scholars are from a variety of disciplines in the health sciences; namely, pediatrics, psychiatry, general medicine, oncology, nursing, human development, music therapy, nutrition, psychology, and social work.

The mixed methods research training program

Formal program activities include two webinars leading up to a retreat followed by ongoing mentorship support. The mixed methods content taught in webinars and the retreat is informed by a widely used textbook by Creswell and Plano Clark [ 18 ] in addition to readings on methodological topics and the practice of mixed methods. The webinars introduce mixed methods research and integration concepts, with the goal of imparting foundational knowledge and ensuring a common language. Specifically, the first webinar introduces mixed methods concepts, research designs, scientific rigor, and becoming a resource at one’s institution, while the second focuses on strategies for the integration of qualitative and quantitative research. Retreats provide an active workshop blending lectures, one-on-one meetings, and interactive faculty-led small workgroups. In addition to scholars, core program faculty who serve as investigators and mentors for the MMRTP, supplemented with consultants and former scholars, lead the retreat. The retreat has covered the state-of-the-art topics within the context of mixed methods research: rationale for use of mixed methods, procedural diagrams, study aims, use of theory, integration strategies, sampling strategies, implementation science, randomized trials, ethics, manuscript and proposal writing, and becoming a resource at one’s home institution. In addition to lectures, the retreat includes multiple interactive small group sessions in which each scholar presents their project and receives feedback on their grant proposal and is expected to make revisions based on feedback and lectures.

Scholars are matched for one year with a mentor based on the Scholar’s needs, career level, and area of health research from a national list of affiliated experienced mixed methods investigators with demonstrated success in obtaining independent funding for research related to the health sciences and a track record and commitment to mentoring. The purpose of this arrangement is to provide different perspectives on mixed methods design while also providing specific feedback on the scholar's research proposal, reviewing new ideas, and together developing a strategy and timeline for submission.

From 2015–2019 (in-person cohorts) the retreat was held over 3 days at the Johns Hopkins University Bloomberg School of Public Health (in 2016 Harvard Catalyst, the Harvard Clinical and Translational Science Center, hosted the retreat at Harvard Medical School). Due to pandemic restrictions, from 2020–2023 the retreat activities were conducted via Zoom with the same number of lecture sessions (over 3 days in 2020 and 4 days thereafter). We made adaptations for the online retreat based on continuous feedback from attendees. We had to rapidly transition to online in 2020 with the same structure as in person, but feedback from scholars led us to extend the retreat to 4 days online from 2021–2023. The extra day allowed for more breaks from Zoom sessions with time for scholars to consider feedback from small groups and to have one-on-one meetings with mentors. Discussion during interactive presentations was encouraged and facilitated by using breakout rooms at breaks mid-presentation. Online resources were available to participants through CoursePlus, the teaching and learning platform used for courses at the Johns Hopkins Bloomberg School of Public Health, hosting publications, presentation materials, recordings of lectures, sharing proposals, email, and discussion boards that scholars have access to before, during, and after the retreat.

Measurement strategy

Before and after the retreat in each year, we distributed a self-administered scholar Mixed Methods Skills Self-Assessment instrument (Supplement 1) to all participating scholars [ 15 ]; we have reported results from this pre-post assessment for the first two cohorts [ 14 ]. The Mixed Methods Skills Self-Assessment instrument has been previously used and has established reliability for the total items (α = 0.95) and evidence of criterion-related validity between experiences and ability ratings [ 15 ]. In each year, the pre-assessment is completed upon entry to the program, approximately four months prior to the retreat, and the post-assessment is administered two weeks after the retreat. The instrument consists of three sections: 1) professional experiences with mixed methods, including background, software, and resource familiarity; 2) a quantitative, qualitative, and mixed methods skills self-assessment; and 3) open-ended questions focused on learning goals for the MMRTP. The skills assessment contains items for each of the following domains: “research questions,” “design/approach,” “sampling,” “analysis,” and “dissemination.” Each skill was assessed via three items drawn from an educational competency ratings scale that ask scholars to rate: [ 16 ] “My ability to define/explain,” “My ability to apply to practical problems,” and “Extent to which I need to improve my skill.” Response options were on a five-point Likert-type scale that ranged from “Not at all” (coded ‘1’) to “To a great extent” (coded ‘5’), including a mid-point [ 17 ]. We took the mean of the scholar’s item ratings over all component items within each domain (namely, “research questions,” “design/approach,” “sampling,” “analysis,” and “dissemination”).

Open-ended questions

The baseline survey included two open-ended prompts: 1) What skills and goals are most important to you?, and 2) What would you like to learn? The post-assessment survey also included two additional open-ended questions about the retreat: 1) What aspects of the retreat were helpful?, and 2) What would you like to change about the retreat? In addition, for the online cohorts (2020–2023), we wanted to understand reactions to the online training and added three questions for this purpose: (1) In general, what did you think of the online format for the MMRTP retreat?, 2) What mixed methods concepts are easier or harder to learn virtually?, and 3) What do you think was missing from having the retreat online rather than in person?

Data analysis

Our evaluation employed a convergent mixed methods design [ 18 ], integrating an analysis of ratings pre- and post-retreat with analysis of open-ended responses provided by scholars after the retreat. Our quantitative analysis proceeded in 3 steps. First, we analyzed item-by-item baseline ratings of the extent to which scholars thought they “need to improve skills,” stratified into two groups (5 cohorts who attended in-person and 4 cohorts who attended online). The purpose of comparing the two groups at baseline on learning needs was to assess how similar the scholars in the in-person or online groups were in self-assessment of learning needs before attending the program. Second, to examine the change in scholar ratings of ability to “define or explain a concept” and in their ability to “apply to practical problems,” from before to after the retreat, we conducted paired t-tests. The goal was to compare the ratings before and after the retreat among scholars who attended the program in person to scholars who attended online. Third, we compared post-retreat ratings among in-person cohorts to online cohorts to gauge the effectiveness of the online training. We set statistical significance at α  < 0.05 as a guide to inference. We calculated Cohen’s d as a guide to the magnitude of differences [ 19 ]. SPSS Version 28 was employed for all analyses.

We analyzed qualitative data using a thematic analysis approach that consisted of reviewing all open-ended responses, conducting open coding based on the data, developing and refining a codebook, and identifying major themes [ 20 ]. We then compared the qualitative results for the in-person versus online cohorts to understand any thematic differences concerning retreat experiences and reactions.

Background and experiences of scholars

Scholars in the in-person ( n  = 59, 81%) and online ( n  = 52, 91%) cohorts reported their primary training was quantitative rather than qualitative or mixed methods, and scholars across cohorts commonly reported at least some exposure to mixed methods research (Table  1 ). However, most scholars did not have previous mixed methods training with 17 (23%) and 16 (28%) of the in-person and online cohorts, respectively, having previously completed a mixed methods course. While experiences were similar across in-person vs. online cohorts, there were two areas in which the scholars reported a statistically significant difference: a larger portion of the online cohorts reported writing a mixed methods application that received funding ( n  = 35, 48% in person; n  = 46, 81% online), and a smaller proportion of the online cohorts had given a local or institutional mixed methods presentation ( n  = 32, 44% in person; n  = 15, 26% online).

Self-identified need to improve skills in mixed methods

At baseline, scholars rated the extent to which they needed to improve specific mixed methods skills (Table  2 ). Overall, scholars endorsed a strong need to improve all mixed methods skills. The ratings between the in-person and online cohorts were not statistically significant for any item.

Change in self-ratings of skills after the retreat

Within cohorts.

For all domains, the differences in pre-post assessment scores were statistically significant for both the in-person and online cohorts in ability to define or explain concepts and to apply concepts to practical problems (left side of Table  3 ). In other words, on average scholars improved in both in-person and online cohorts.

Across cohorts

Online cohorts had significantly better self-ratings after the retreat than did in-person cohorts in ability to define or explain concepts and to apply concepts to practical problems (in sampling, data collection, analysis, and dissemination) but no significant differences in research questions and design / approach (rightmost column of Table  3 ).

Scholar reflections about online and in-person retreats

Goals of training.

In comparing in-person to online cohorts, discussions of the skills that scholars wanted to improve had no discernable differences. Scholars mentioned wanting to develop skills in the foundations of mixed methods research, how to write competitive proposals for funding, the use of the terminology of mixed methods research, and integrative analysis. In addition, some scholars expressed wanting to become a resource at their own institutions and providing training and mentoring to others.

Small group sessions

Scholars consistently reported appreciating being able to talk through their project and gaining feedback from experts in small group sessions. Some scholars expressed a preference for afternoon small group sessions, “The small group sessions felt the most helpful, but only because we can apply what we were learning from the morning lecture sessions” (online cohort 9). How participants discussed the benefits of the small group sessions or how they used the sessions did not depend on whether they had experienced the session in person or online.

Online participants described a tradeoff between the accessibility of a virtual retreat versus advantages of in-person training. One participant explained, “I liked the online format, as I do not have reliable childcare” (online cohort 8). Many of the scholars felt that there was an aspect of networking missing when the retreat was held fully online. As one scholar described, when learning online they, “miss getting to know the other fellows and forming lasting connections” (online cohort 9). However, an equal number of others reported that having a virtual retreat meant less hassle; for instance, they were able to join from their preferred location and did not have to travel. Some individuals specifically described the tradeoff of fewer networking opportunities for ease of attendance. One scholar wrote, being online “certainly loses some of the perks of in person connection building but made it equitable to attend” (online cohort 8).

Learning online

No clear difference in ease of learning concepts was described. A scholar explained: “Learning most concepts is essentially the same virtually versus in person” (online cohort 8). However, scholars described some concepts as easier to learn in one modality versus the other, for example, simpler concepts being more suited to learning virtually while complex concepts were better suited to in-person learning. There was notable variation though in the topics which scholars considered to be simple versus complex. For instance, one scholar noted that “I suppose developing the joint displays were a bit tougher virtually since you were not literally elbow to elbow” (online cohort 7) while another explained, “joint displays lend themselves to the zoom format” (online cohort 8).

Integrating survey responses and scholar reflections

In-person and online cohorts were comparable in professional experiences and ratings of the need to improve skills before attending the retreat, sharpening the focus on differences in self-rated skills associated with attendance online compared to in person. If anything, online attendees rated skills as good or better than in-person attendees. Open-ended questions revealed that, for the most part, scholar reflections on learning were similar across in-person and online cohorts. Whether learning the concept of “mixed methods integration” was more difficult online was a source of disagreement. Online attendance was associated with numerous advantages, and small group sessions were valued, regardless of format. Taken together, the evidence from nine cohorts shows that the online retreat was acceptable and as effective in improving self-rated skills as meeting in person.

Mixed methods have become indispensable to health services research from intervention development and testing [ 21 ] to implementation science [ 22 , 23 , 24 ]. We found that scholars participating in an interactive program to improve mixed methods skills reported significantly increased confidence in their ability to define or explain concepts and in their ability to apply the concepts to practical problems, whether the program was attended in-person or synchronously online. Scholars who participated in the online retreat had self-rated skill improvements as good or better than scholars who participated in person, and these improvements were relatively large as indicated by the Cohen’s d estimates. The online retreat appeared to be effective in increasing confidence in the use of mixed methods research in the health sciences and was acceptable to scholars. Our study deserves attention because the national need is so great for investigators with training in mixed methods to address complex behavioral health problems, community- and patient-centered research, and implementation research. No program has been evaluated as we have done here.

Aside from having written a funded mixed methods proposal, the online compared to earlier in person cohorts were comparable in experiences and need to improve specific skills. Within each cohort, scholars reported significant gains in self-rated skills on their ability to “define or explain” a concept and on their ability to “apply to practical problems” in domains essential to mixed methods research. However, consistent with our hypothesis that online training would be as effective as in person we found that online scholars reported better improvement in self-ratings in ability to define or explain concepts and to apply concepts to practical problems in sampling, data collection, analysis, and dissemination but no significant differences in research questions and design / approach. Better ratings in online cohorts could reflect differences in experience with mixed methods, secular changes in knowledge and availability of resources in mixed methods, and maturation of the program facilitated by continued modifications based on feedback from scholars and participating faculty [ 13 , 14 , 15 ].

Ratings related to the “analysis” domain, which includes the central concept of mixed methods integration, deserve notice since scholars rated this skill well below other domains at baseline. While both in-person and online cohorts improved after the retreat, and online cohorts improved substantially more than in-person cohorts, ratings for analysis after the retreat remained lower than for other domains. Scholars consistently have mentioned integration as a difficult concept, and our analysis here is limited to the retreat alone. Continued mentoring one year after the retreat and work on their proposal is built in to the MMRTP to enhance understanding of integration.

Several reviews point out the advantages of online training including savings in time, money, and greenhouse emissions [ 1 , 7 , 8 ]. Online conferences may increase the reach of training to international audiences, improve the diversity of speakers and attendees, facilitate attendance of persons with disabilities, and ease the burden of finding childcare [ 1 , 8 , 25 ]. Online training in health also appears to be effective [ 2 , 4 , 5 , 25 ], though studies are limited because often no skills were evaluated, no comparison groups were used, the response rate was low, or the sample size was small [ 1 , 6 ]. With the possible exception of networking, scholars found the online format was associated with advantages, including saving travel, maintaining work-family balance, and learning effectively. As scholars did discuss perceived increase in difficulty networking, deliberate effort needs to be directed at enhancing collaborations and mentorship [ 8 ]. The MMRTP was designed with components to facilitate networking during and beyond the retreat (e.g., small group sessions, one-on-one meetings, working with a consultant on a specific proposal).

Limitations of our study should be considered. First, the retreat was only one of several components of a mentoring program for faculty in the health sciences. Second, in-person and online cohorts represent different time periods spanning 9 years during which mixed methods applications to NIH and other funders have been increasing [ 9 ]. Third, the pre- and post-evaluations of ability to explain or define concepts, or to apply the concepts to practical problems, were based on self-report. Nevertheless, the pre-post retreat survey on self-rated skills uses a skills self-assessment form we developed [ 15 ], drawing from educational theory related to the epistemology of knowledge [ 26 , 27 ].

Despite the central role of mixed methods in health research, studies evaluating online methods training in the health sciences are nonexistent. Our study provides evidence that mixed methods training online was associated with the same increases in self-rated skills as persons attending online and can be a key component to increasing the capacity for mixed methods research in the health sciences.

  5. How to write the rationale for research?| [site:name]

    To write your rationale, you should first write a background on what all research has been done on your study topic. Follow this with 'what is missing' or 'what are the open questions of the study'. Identify the gaps in the literature and emphasize why it is important to address those gaps. This will form the rationale of your study.

  6. Writing a rationale

    What is a rationale? A rationale is when you are asked to give the reasoning or justification for an action or a choice you make. There is a focus on the 'why' in a rationale: why you chose to do something, study or focus on something. It is a set of statements of purpose and significance and often addresses a gap or a need.

  7. A Practical Guide to Writing Quantitative and Qualitative Research

    INTRODUCTION. Scientific research is usually initiated by posing evidenced-based research questions which are then explicitly restated as hypotheses.1,2 The hypotheses provide directions to guide the study, solutions, explanations, and expected results.3,4 Both research questions and hypotheses are essentially formulated based on conventional theories and real-world processes, which allow the ...

Whilst a research question indicates the topic or issue of the study, research objectives operationalise the question, in other words they state precisely what needs to be researched. Research objectives are therefore instrumental in enabling the research question to evolve into an actual study.

  11. How to write the rationale for your research

    19 November, 2021. The rationale for one's research is the justification for undertaking a given study. It states the reason (s) why a researcher chooses to focus on the topic in question, including what the significance is and what gaps the research intends to fill. In short, it is an explanation that rationalises the need for the study.

  12. Rationale for the Study

    Rationale for the study, also referred to as justification for the study, is reason why you have conducted your study in the first place. This part in your paper needs to explain uniqueness and importance of your research. Rationale for the study needs to be specific and ideally, it should relate to the following points: 1. The research needs ...
