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

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.

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.

7 Examples of Justification (of a project or research)

The justification to the part of a research project that sets out the reasons that motivated the research. The justification is the section that explains the importance and the reasons that led the researcher to carry out the work.

The justification explains to the reader why and why the chosen topic was investigated. In general, the reasons that the researcher can give in a justification may be that his work allows to build or refute theories; bring a new approach or perspective on the subject; contribute to the solution of a specific problem (social, economic, environmental, etc.) that affects certain people; generate meaningful and reusable empirical data; clarify the causes and consequences of a specific phenomenon of interest; among other.

Among the criteria used to write a justification, the usefulness of the research for other academics or for other social sectors (public officials, companies, sectors of civil society), the significance in time that it may have, the contribution of new research tools or techniques, updating of existing knowledge, among others. Also, the language should be formal and descriptive.

Examples of justification

This research will focus on studying the reproduction habits of salmon in the Mediterranean region of Europe, since due to recent ecological changes in the water and temperatures of the region produced by human economic activity , the behavior of these animals has been modified. Thus, the present work would allow to show the changes that the species has developed to adapt to the new circumstances of its ecosystem, and to deepen the theoretical knowledge about accelerated adaptation processes, in addition to offering a comprehensive look at the environmental damage caused by growth. unsustainable economic, helping to raise awareness of the local population.
We therefore propose to investigate the evolution of the theoretical conceptions of class struggle and economic structure throughout the work of Antonio Gramsci, since we consider that previous analyzes have overlooked the fundamentally dynamic and unstable conception of human society that is present. in the works of Gramsci, and that is of vital importance to fully understand the author’s thought.
The reasons that led us to investigate the effects of regular use of cell phones on the health of middle-class young people under 18 years of age are centered on the fact that this vulnerable sector of the population is exposed to a greater extent than the rest of society to risks that the continuous use of cell phone devices may imply, due to their cultural and social habits. We intend then to help alert about these dangers, as well as to generate knowledge that helps in the treatment of the effects produced by the abuse in the use of this technology.
We believe that by means of a detailed analysis of the evolution of financial transactions carried out in the main stock exchanges of the world during the period 2005-2010, as well as the inquiry about how financial and banking agents perceived the situation of the financial system, it will allow us to clarify the economic mechanisms that enable the development of an economic crisis of global dimensions such as the one that the world experienced since 2009, and thus improve the design of regulatory and counter-cyclical public policies that favor the stability of the local and international financial system.
Our study about the applications and programs developed through the three analyzed programming languages (Java, C ++ and Haskell), can allow us to clearly distinguish the potential that each of these languages (and similar languages) present for solving specific problems. , in a specific area of activity. This would allow not only to increase efficiency in relation to long-term development projects, but to plan coding strategies with better results in projects that are already working, and to improve teaching plans for teaching programming and computer science.
This in-depth study on the expansion of the Chinese empire under the Xia dynasty, will allow to clarify the socioeconomic, military and political processes that allowed the consolidation of one of the oldest states in history, and also understand the expansion of metallurgical and administrative technologies along the coastal region of the Pacific Ocean. The deep understanding of these phenomena will allow us to clarify this little-known period in Chinese history, which was of vital importance for the social transformations that the peoples of the region went through during the period.
Research on the efficacy of captropil in the treatment of cardiovascular conditions (in particular hypertension and heart failure) will allow us to determine if angiotensin is of vital importance in the processes of blocking the protein peptidase, or if by the On the contrary, these effects can be attributed to other components present in the formula of drugs frequently prescribed to patients after medical consultation.
