how to write an abstract for a biography

Examples of Biographical Statement and Abstract

Biographical statement.

Once articles have been selected and accepted for publication each year, authors will be asked to submit a biographical statement to be included in the Advocates’ Forum . The biographical statement should include the author(s) full name. In addition, it is also appropriate to discuss your personal history, academic program and/or field placement, and interest in the article’s subject. The biographical statement may not exceed 75 words. Below is an example taken from the 2009 volume of the Advocates’ Forum :

"Kathryn Saclarides is a second-year social administration student at the University of Chicago Crown Family School of Social Work, Policy, and Practice. She received a bachelor’s degree in anthropology and Spanish from Vanderbilt University and a master’s degree in bioethics from La Universidad Pontificia de Comillas in Madrid, Spain. Her current field placement is with the National Alliance of Latin American and Caribbean Communities (NALACC). She is interested in migration patterns, ethnic neighborhoods, and transnational communities."

The abstract should appear on the second page of your manuscript, immediately following the title page. The abstract should briefly summarize the argument advanced in your manuscript, and should be limited to no more than 100 words. For additional guidance on composing abstracts, refer to the  Publication Manual of the American Psychological Association . Below is an example taken from an issue of Advocates’ Forum (Charlotte L. Hamilton, “Anti-Drug Legislation and the Rising Incarceration of Women: Recommendations for Future Sentencing Reform,” Advocates’ Forum [2005]: 33-43).

The Anti-Drug Abuse Acts of 1986 and 1988 led to a rapid increase in the number of incarcerated Americans. The rate of female incarceration has risen at a particularly high rate over the past 20 years. This article discusses the evolution of drug sentencing policy since 1986. It looks at characteristics of incarcerated women in order to understand how drug policy has influenced this population. The way women participate in the drug trade interacts with minimum sentencing laws to contribute to the rise in female incarceration. The article concludes with policy recommendations for a more equitable drug sentencing system.

How to Write an Academic Bio for Conferences

There are very few things as challenging as writing academic biographies (perhaps academic writing?). It seems simple, but things soon get awkward as you try to show how amazing you are without sounding arrogation or pretentious. Sophie shares her tips on writing a balanced bio…

It’s all going swimmingly until you read the Call for Papers: Please submit a proposal and brief bio.

What on earth is a bio (otherwise known as an ‘academic bio’)? And just how brief does it need to be? Writing an academic bio is a skill you can pick up like any other, and this article will take you through the basics of what to include, what to leave out, and how to craft this tricky piece of your academic arsenal.

Covering the Basics

Whatever discipline you’re working in, you’ll definitely need to include the following in your academic bio:

•  full name,
• position (i.e. PhD student; PhD candidate),
• institution.

All this should go into the first sentence, so it reads something like this:

Joe Bloggs is currently a PhD candidate [meaning he’s passed his upgrade] at the University of Warwick.

You can also mention your department, although it’s not strictly necessary for most of us.

The Big Picture

The rest of your academic bio should tell the reader about your research interests. Start by setting out your broad research question , whether that’s finding new ways to create Omega 3 in algae cultures or exploring fashion statements at Charles II’s court. Then focus it further; are you looking at a specific type of algae culture, or a particular poet who was into fashion? This is the most important part of your bio: it tells other people attending the conference where you’re coming from, and may present links between your research areas.

You can end your bio here, or add another sentence situating your research within wider scholarship. Is it important to reference your specific style of criticism, or how you’re leading on from recently-published developments in the field, for example? If it’s important for the theme of the conference, you may wish to add another sentence on the future directions of your research. However, if this isn’t relevant or necessary, feel free to leave it out, especially if you’ve been asked to submit a brief bio – best to keep it brief and stick to your research interests.

What Not to Do

Inevitably, we all do things early in our career/academic life that, with hindsight, make us cringe. To avoid that uncomfortable feeling in the future, four common errors are:

• Treating your bio like a humorous essay : only include a joke if you’re sure it’s really, really funny (maybe check with a straight-talking friend).
• Getting too personal : an academic bio is a chance to make an impression pre-conference, and it may be what people remember you by, so ensure that you stay professional.
• Giving too much information : remember that an academic bio isn’t the same thing as a CV – the conference organisers don’t need to know where you did your undergrad, MA or how much you’ve won in grants.
• Using exclamation marks : your writing should be relatively formal in style, so avoid coming across as too chatty – save your engaging manners for the big presentation day!

One final tip is to use the third person. This isn’t a hard and fast rule, but at some conferences, your bio will be read out as an introduction, so personally I prefer to start a sentence like Joe Bloggs above.

What do you think about this approach?

Any more tips for writing academic bios?

Preparation of an Abstract and Biography

In this section, preparation of an abstract.

The abstract should be written concisely in normal rather than highly abbreviated English. The author should assume that the reader has some knowledge of the subject but has not read the paper. Thus, the abstract should be intelligible and complete in itself (no numerical references); it should not cite figures, tables, or sections of the paper. The abstract should be written using third person instead of first person (i.e., “The experiments were performed” versus “We performed the experiments…”).

The title normally is read along with the abstract and so should not be repeated or paraphrased in the first sentence of the abstract. The opening sentences should, in general, indicate the subjects dealt with in the paper (unless the title identifies them adequately) and should state the objectives of the investigation. It is also desirable to describe the treatment by one or more such terms as brief, exhaustive, theoretical, experimental, and so forth.  The body of the abstract should indicate newly observed facts and the conclusions of the experiment or argument discussed in the paper. It should contain new numerical data presented in the paper if space permits; otherwise, attention should be drawn to the nature of such data. In the case of experimental results, the abstract should indicate the methods used in obtaining them; for new methods the basic principle, range of operation, and degree of accuracy should be given.

The abstract must appear as one paragraph. Its optimum length will vary somewhat with the nature and extent of the paper, but it must range from a minimum of 100 to a maximum of 200 words. 

Preparation of a Biography

Journal Survey papers, Lectures, and History papers include one-paragraph biographies of the authors along with their photographs.

Biographies should be professional rather than personal in nature and must include the author’s current affiliation and AIAA membership status, if applicable. Degrees earned, professional awards received, and relevant contributions to the field should be included, along with prior, relevant work experience. The author’s publishing history also may be included, if appropriate.

Length and Style

The biography should appear as one paragraph. Its optimum length will vary somewhat, but it should range from 100 to a maximum of 250 words. Abbreviate academic degrees rather than spelling them out, and include periods in the abbreviations. Spell out names of disciplines  instead of using common abbreviations; e.g., instead of M.S.C.E., use M.S. in civil engineering.

How to Write a Good Academic Biography (Part 1)

When your journal article gets accepted or you are preparing for a public presentation, you will often be asked for a short academic biography. For many people, these academic bios are more difficult to write than a dissertation. How do you sum up yourself and your work in 3-5 sentences? What do you need to include? What should you leave out?

What You Should Do

• Start with your full name followed by your current position, your general interests, and your current project, keeping them all very brief.
• If you are within a year of receiving a prestigious award, mention that as well.
• Finally, finish with a sentence that’s personal: add a hobby, a pet’s name, the city you live in—whatever you are comfortable with that is personal but not too private.

What You Should Avoid

• Avoid speaking in the first person, i.e., don’t use “I.”
• Don’t divulge details beyond your current position.
• In a longer bio of multiple paragraphs, you may add more awards and information about your master’s and bachelor’s degrees, but not in a short bio. Moreover, don’t add anything that happened before grad school—including your place of birth. For example:

Hi! My name is Scott. I was originally born in Vermont and now I’m a professor at North Yankee University in Fargone, New York (in upstate New York). I study antelopes’ migration patterns and their impact of native grain growth. My interest in antelopes began as a teenager when I first saw one in the wild. I did my undergrad degree in biology at SUNY and my masters and UCLA and my PhD in Forestry at Hunter College.

The above example is far too casual and Scott’s work and current position are overshadowed by all the other random details. This can be written in a much better way:

Scott Sampson is a professor of Wildlife Biology at North Yankee University. His work focuses specifically on the migration patterns of antelope and their impact on the growth of native grain. His favorite place to do research in his backyard, which opens to the Akron National Forest.

This improvised version is concise, relevant, and makes Scott’s bio appear professional while giving a short description of his personal details.

Longer Bios

For longer bios, follow the same basic rules, but go into a bit more depth about your work, your education, and your future projects or interests. You may also consider adding a line about your immediate family. But as always, leave the personal details for a short and friendly mention at the end of the bio.

Mostly, your bio will be used by someone to introduce you at a conference or public event so if you write your bio using these tips, you will help them give a smooth and accurate introduction. Remember that the bio is the first thing that people know about you so pack it full of the most important things about yourself!

How to Write an Abstract (With Examples)

Sarah Oakley

Table of Contents

What is an abstract in a paper, how long should an abstract be, 5 steps for writing an abstract, examples of an abstract, how prowritingaid can help you write an abstract.

If you are writing a scientific research paper or a book proposal, you need to know how to write an abstract, which summarizes the contents of the paper or book.

When researchers are looking for peer-reviewed papers to use in their studies, the first place they will check is the abstract to see if it applies to their work. Therefore, your abstract is one of the most important parts of your entire paper.

In this article, we’ll explain what an abstract is, what it should include, and how to write one.

An abstract is a concise summary of the details within a report. Some abstracts give more details than others, but the main things you’ll be talking about are why you conducted the research, what you did, and what the results show.

When a reader is deciding whether to read your paper completely, they will first look at the abstract. You need to be concise in your abstract and give the reader the most important information so they can determine if they want to read the whole paper.

Remember that an abstract is the last thing you’ll want to write for the research paper because it directly references parts of the report. If you haven’t written the report, you won’t know what to include in your abstract.

If you are writing a paper for a journal or an assignment, the publication or academic institution might have specific formatting rules for how long your abstract should be. However, if they don’t, most abstracts are between 150 and 300 words long.

A short word count means your writing has to be precise and without filler words or phrases. Once you’ve written a first draft, you can always use an editing tool, such as ProWritingAid, to identify areas where you can reduce words and increase readability.

If your abstract is over the word limit, and you’ve edited it but still can’t figure out how to reduce it further, your abstract might include some things that aren’t needed. Here’s a list of three elements you can remove from your abstract:

Discussion : You don’t need to go into detail about the findings of your research because your reader will find your discussion within the paper.

Definition of terms : Your readers are interested the field you are writing about, so they are likely to understand the terms you are using. If not, they can always look them up. Your readers do not expect you to give a definition of terms in your abstract.

References and citations : You can mention there have been studies that support or have inspired your research, but you do not need to give details as the reader will find them in your bibliography.

Good writing = better grades

ProWritingAid will help you improve the style, strength, and clarity of all your assignments.

If you’ve never written an abstract before, and you’re wondering how to write an abstract, we’ve got some steps for you to follow. It’s best to start with planning your abstract, so we’ve outlined the details you need to include in your plan before you write.

Remember to consider your audience when you’re planning and writing your abstract. They are likely to skim read your abstract, so you want to be sure your abstract delivers all the information they’re expecting to see at key points.

1. What Should an Abstract Include?

Abstracts have a lot of information to cover in a short number of words, so it’s important to know what to include. There are three elements that need to be present in your abstract:

Your context is the background for where your research sits within your field of study. You should briefly mention any previous scientific papers or experiments that have led to your hypothesis and how research develops in those studies.

Your hypothesis is your prediction of what your study will show. As you are writing your abstract after you have conducted your research, you should still include your hypothesis in your abstract because it shows the motivation for your paper.

Throughout your abstract, you also need to include keywords and phrases that will help researchers to find your article in the databases they’re searching. Make sure the keywords are specific to your field of study and the subject you’re reporting on, otherwise your article might not reach the relevant audience.

2. Can You Use First Person in an Abstract?

You might think that first person is too informal for a research paper, but it’s not. Historically, writers of academic reports avoided writing in first person to uphold the formality standards of the time. However, first person is more accepted in research papers in modern times.

If you’re still unsure whether to write in first person for your abstract, refer to any style guide rules imposed by the journal you’re writing for or your teachers if you are writing an assignment.

3. Abstract Structure

Some scientific journals have strict rules on how to structure an abstract, so it’s best to check those first. If you don’t have any style rules to follow, try using the IMRaD structure, which stands for Introduction, Methodology, Results, and Discussion.

Following the IMRaD structure, start with an introduction. The amount of background information you should include depends on your specific research area. Adding a broad overview gives you less room to include other details. Remember to include your hypothesis in this section.

The next part of your abstract should cover your methodology. Try to include the following details if they apply to your study:

What type of research was conducted?

How were the test subjects sampled?

What were the sample sizes?

What was done to each group?

How long was the experiment?

How was data recorded and interpreted?

Following the methodology, include a sentence or two about the results, which is where your reader will determine if your research supports or contradicts their own investigations.

The results are also where most people will want to find out what your outcomes were, even if they are just mildly interested in your research area. You should be specific about all the details but as concise as possible.

The last few sentences are your conclusion. It needs to explain how your findings affect the context and whether your hypothesis was correct. Include the primary take-home message, additional findings of importance, and perspective. Also explain whether there is scope for further research into the subject of your report.

Your conclusion should be honest and give the reader the ultimate message that your research shows. Readers trust the conclusion, so make sure you’re not fabricating the results of your research. Some readers won’t read your entire paper, but this section will tell them if it’s worth them referencing it in their own study.

4. How to Start an Abstract

The first line of your abstract should give your reader the context of your report by providing background information. You can use this sentence to imply the motivation for your research.

You don’t need to use a hook phrase or device in your first sentence to grab the reader’s attention. Your reader will look to establish relevance quickly, so readability and clarity are more important than trying to persuade the reader to read on.

5. How to Format an Abstract

Most abstracts use the same formatting rules, which help the reader identify the abstract so they know where to look for it.

Here’s a list of formatting guidelines for writing an abstract:

Stick to one paragraph

Use block formatting with no indentation at the beginning

Put your abstract straight after the title and acknowledgements pages

Use present or past tense, not future tense

There are two primary types of abstract you could write for your paper—descriptive and informative.

An informative abstract is the most common, and they follow the structure mentioned previously. They are longer than descriptive abstracts because they cover more details.

Descriptive abstracts differ from informative abstracts, as they don’t include as much discussion or detail. The word count for a descriptive abstract is between 50 and 150 words.

Here is an example of an informative abstract:

A growing trend exists for authors to employ a more informal writing style that uses “we” in academic writing to acknowledge one’s stance and engagement. However, few studies have compared the ways in which the first-person pronoun “we” is used in the abstracts and conclusions of empirical papers. To address this lacuna in the literature, this study conducted a systematic corpus analysis of the use of “we” in the abstracts and conclusions of 400 articles collected from eight leading electrical and electronic (EE) engineering journals. The abstracts and conclusions were extracted to form two subcorpora, and an integrated framework was applied to analyze and seek to explain how we-clusters and we-collocations were employed. Results revealed whether authors’ use of first-person pronouns partially depends on a journal policy. The trend of using “we” showed that a yearly increase occurred in the frequency of “we” in EE journal papers, as well as the existence of three “we-use” types in the article conclusions and abstracts: exclusive, inclusive, and ambiguous. Other possible “we-use” alternatives such as “I” and other personal pronouns were used very rarely—if at all—in either section. These findings also suggest that the present tense was used more in article abstracts, but the present perfect tense was the most preferred tense in article conclusions. Both research and pedagogical implications are proffered and critically discussed.

Wang, S., Tseng, W.-T., & Johanson, R. (2021). To We or Not to We: Corpus-Based Research on First-Person Pronoun Use in Abstracts and Conclusions. SAGE Open, 11(2).

Here is an example of a descriptive abstract:

From the 1850s to the present, considerable criminological attention has focused on the development of theoretically-significant systems for classifying crime. This article reviews and attempts to evaluate a number of these efforts, and we conclude that further work on this basic task is needed. The latter part of the article explicates a conceptual foundation for a crime pattern classification system, and offers a preliminary taxonomy of crime.

If you want to ensure your abstract is grammatically correct and easy to read, you can use ProWritingAid to edit it. The software integrates with Microsoft Word, Google Docs, and most web browsers, so you can make the most of it wherever you’re writing your paper.

Before you edit with ProWritingAid, make sure the suggestions you are seeing are relevant for your document by changing the document type to “Abstract” within the Academic writing style section.

You can use the Readability report to check your abstract for places to improve the clarity of your writing. Some suggestions might show you where to remove words, which is great if you’re over your word count.

We hope the five steps and examples we’ve provided help you write a great abstract for your research paper.

Writing an Abstract for Your Research Paper

Definition and Purpose of Abstracts

An abstract is a short summary of your (published or unpublished) research paper, usually about a paragraph (c. 6-7 sentences, 150-250 words) long. A well-written abstract serves multiple purposes:

• an abstract lets readers get the gist or essence of your paper or article quickly, in order to decide whether to read the full paper;
• an abstract prepares readers to follow the detailed information, analyses, and arguments in your full paper;
• and, later, an abstract helps readers remember key points from your paper.

It’s also worth remembering that search engines and bibliographic databases use abstracts, as well as the title, to identify key terms for indexing your published paper. So what you include in your abstract and in your title are crucial for helping other researchers find your paper or article.

If you are writing an abstract for a course paper, your professor may give you specific guidelines for what to include and how to organize your abstract. Similarly, academic journals often have specific requirements for abstracts. So in addition to following the advice on this page, you should be sure to look for and follow any guidelines from the course or journal you’re writing for.

The Contents of an Abstract

Abstracts contain most of the following kinds of information in brief form. The body of your paper will, of course, develop and explain these ideas much more fully. As you will see in the samples below, the proportion of your abstract that you devote to each kind of information—and the sequence of that information—will vary, depending on the nature and genre of the paper that you are summarizing in your abstract. And in some cases, some of this information is implied, rather than stated explicitly. The Publication Manual of the American Psychological Association , which is widely used in the social sciences, gives specific guidelines for what to include in the abstract for different kinds of papers—for empirical studies, literature reviews or meta-analyses, theoretical papers, methodological papers, and case studies.

Here are the typical kinds of information found in most abstracts:

• the context or background information for your research; the general topic under study; the specific topic of your research
• the central questions or statement of the problem your research addresses
• what’s already known about this question, what previous research has done or shown
• the main reason(s) , the exigency, the rationale , the goals for your research—Why is it important to address these questions? Are you, for example, examining a new topic? Why is that topic worth examining? Are you filling a gap in previous research? Applying new methods to take a fresh look at existing ideas or data? Resolving a dispute within the literature in your field? . . .
• your research and/or analytical methods
• your main findings , results , or arguments
• the significance or implications of your findings or arguments.

Your abstract should be intelligible on its own, without a reader’s having to read your entire paper. And in an abstract, you usually do not cite references—most of your abstract will describe what you have studied in your research and what you have found and what you argue in your paper. In the body of your paper, you will cite the specific literature that informs your research.

When to Write Your Abstract

Although you might be tempted to write your abstract first because it will appear as the very first part of your paper, it’s a good idea to wait to write your abstract until after you’ve drafted your full paper, so that you know what you’re summarizing.

What follows are some sample abstracts in published papers or articles, all written by faculty at UW-Madison who come from a variety of disciplines. We have annotated these samples to help you see the work that these authors are doing within their abstracts.

Choosing Verb Tenses within Your Abstract

The social science sample (Sample 1) below uses the present tense to describe general facts and interpretations that have been and are currently true, including the prevailing explanation for the social phenomenon under study. That abstract also uses the present tense to describe the methods, the findings, the arguments, and the implications of the findings from their new research study. The authors use the past tense to describe previous research.

The humanities sample (Sample 2) below uses the past tense to describe completed events in the past (the texts created in the pulp fiction industry in the 1970s and 80s) and uses the present tense to describe what is happening in those texts, to explain the significance or meaning of those texts, and to describe the arguments presented in the article.

The science samples (Samples 3 and 4) below use the past tense to describe what previous research studies have done and the research the authors have conducted, the methods they have followed, and what they have found. In their rationale or justification for their research (what remains to be done), they use the present tense. They also use the present tense to introduce their study (in Sample 3, “Here we report . . .”) and to explain the significance of their study (In Sample 3, This reprogramming . . . “provides a scalable cell source for. . .”).

Sample Abstract 4, a Structured Abstract

Reporting results about the effectiveness of antibiotic therapy in managing acute bacterial sinusitis, from a rigorously controlled study

Note: This journal requires authors to organize their abstract into four specific sections, with strict word limits. Because the headings for this structured abstract are self-explanatory, we have chosen not to add annotations to this sample abstract.

Wald, Ellen R., David Nash, and Jens Eickhoff. “Effectiveness of Amoxicillin/Clavulanate Potassium in the Treatment of Acute Bacterial Sinusitis in Children.” Pediatrics , vol. 124, no. 1, 2009, pp. 9-15.

“OBJECTIVE: The role of antibiotic therapy in managing acute bacterial sinusitis (ABS) in children is controversial. The purpose of this study was to determine the effectiveness of high-dose amoxicillin/potassium clavulanate in the treatment of children diagnosed with ABS.

METHODS : This was a randomized, double-blind, placebo-controlled study. Children 1 to 10 years of age with a clinical presentation compatible with ABS were eligible for participation. Patients were stratified according to age (<6 or ≥6 years) and clinical severity and randomly assigned to receive either amoxicillin (90 mg/kg) with potassium clavulanate (6.4 mg/kg) or placebo. A symptom survey was performed on days 0, 1, 2, 3, 5, 7, 10, 20, and 30. Patients were examined on day 14. Children’s conditions were rated as cured, improved, or failed according to scoring rules.

RESULTS: Two thousand one hundred thirty-five children with respiratory complaints were screened for enrollment; 139 (6.5%) had ABS. Fifty-eight patients were enrolled, and 56 were randomly assigned. The mean age was 6630 months. Fifty (89%) patients presented with persistent symptoms, and 6 (11%) presented with nonpersistent symptoms. In 24 (43%) children, the illness was classified as mild, whereas in the remaining 32 (57%) children it was severe. Of the 28 children who received the antibiotic, 14 (50%) were cured, 4 (14%) were improved, 4(14%) experienced treatment failure, and 6 (21%) withdrew. Of the 28children who received placebo, 4 (14%) were cured, 5 (18%) improved, and 19 (68%) experienced treatment failure. Children receiving the antibiotic were more likely to be cured (50% vs 14%) and less likely to have treatment failure (14% vs 68%) than children receiving the placebo.

CONCLUSIONS : ABS is a common complication of viral upper respiratory infections. Amoxicillin/potassium clavulanate results in significantly more cures and fewer failures than placebo, according to parental report of time to resolution.” (9)

What this handout is about

This handout provides definitions and examples of the two main types of abstracts: descriptive and informative. It also provides guidelines for constructing an abstract and general tips for you to keep in mind when drafting. Finally, it includes a few examples of abstracts broken down into their component parts.

What is an abstract?

An abstract is a self-contained, short, and powerful statement that describes a larger work. Components vary according to discipline. An abstract of a social science or scientific work may contain the scope, purpose, results, and contents of the work. An abstract of a humanities work may contain the thesis, background, and conclusion of the larger work. An abstract is not a review, nor does it evaluate the work being abstracted. While it contains key words found in the larger work, the abstract is an original document rather than an excerpted passage.

Why write an abstract?

You may write an abstract for various reasons. The two most important are selection and indexing. Abstracts allow readers who may be interested in a longer work to quickly decide whether it is worth their time to read it. Also, many online databases use abstracts to index larger works. Therefore, abstracts should contain keywords and phrases that allow for easy searching.

Say you are beginning a research project on how Brazilian newspapers helped Brazil’s ultra-liberal president Luiz Ignácio da Silva wrest power from the traditional, conservative power base. A good first place to start your research is to search Dissertation Abstracts International for all dissertations that deal with the interaction between newspapers and politics. “Newspapers and politics” returned 569 hits. A more selective search of “newspapers and Brazil” returned 22 hits. That is still a fair number of dissertations. Titles can sometimes help winnow the field, but many titles are not very descriptive. For example, one dissertation is titled “Rhetoric and Riot in Rio de Janeiro.” It is unclear from the title what this dissertation has to do with newspapers in Brazil. One option would be to download or order the entire dissertation on the chance that it might speak specifically to the topic. A better option is to read the abstract. In this case, the abstract reveals the main focus of the dissertation:

This dissertation examines the role of newspaper editors in the political turmoil and strife that characterized late First Empire Rio de Janeiro (1827-1831). Newspaper editors and their journals helped change the political culture of late First Empire Rio de Janeiro by involving the people in the discussion of state. This change in political culture is apparent in Emperor Pedro I’s gradual loss of control over the mechanisms of power. As the newspapers became more numerous and powerful, the Emperor lost his legitimacy in the eyes of the people. To explore the role of the newspapers in the political events of the late First Empire, this dissertation analyzes all available newspapers published in Rio de Janeiro from 1827 to 1831. Newspapers and their editors were leading forces in the effort to remove power from the hands of the ruling elite and place it under the control of the people. In the process, newspapers helped change how politics operated in the constitutional monarchy of Brazil.

From this abstract you now know that although the dissertation has nothing to do with modern Brazilian politics, it does cover the role of newspapers in changing traditional mechanisms of power. After reading the abstract, you can make an informed judgment about whether the dissertation would be worthwhile to read.

Besides selection, the other main purpose of the abstract is for indexing. Most article databases in the online catalog of the library enable you to search abstracts. This allows for quick retrieval by users and limits the extraneous items recalled by a “full-text” search. However, for an abstract to be useful in an online retrieval system, it must incorporate the key terms that a potential researcher would use to search. For example, if you search Dissertation Abstracts International using the keywords “France” “revolution” and “politics,” the search engine would search through all the abstracts in the database that included those three words. Without an abstract, the search engine would be forced to search titles, which, as we have seen, may not be fruitful, or else search the full text. It’s likely that a lot more than 60 dissertations have been written with those three words somewhere in the body of the entire work. By incorporating keywords into the abstract, the author emphasizes the central topics of the work and gives prospective readers enough information to make an informed judgment about the applicability of the work.

When do people write abstracts?

• when submitting articles to journals, especially online journals
• when applying for research grants
• when writing a book proposal
• when completing the Ph.D. dissertation or M.A. thesis
• when writing a proposal for a conference paper
• when writing a proposal for a book chapter

Most often, the author of the entire work (or prospective work) writes the abstract. However, there are professional abstracting services that hire writers to draft abstracts of other people’s work. In a work with multiple authors, the first author usually writes the abstract. Undergraduates are sometimes asked to draft abstracts of books/articles for classmates who have not read the larger work.

Types of abstracts

There are two types of abstracts: descriptive and informative. They have different aims, so as a consequence they have different components and styles. There is also a third type called critical, but it is rarely used. If you want to find out more about writing a critique or a review of a work, see the UNC Writing Center handout on writing a literature review . If you are unsure which type of abstract you should write, ask your instructor (if the abstract is for a class) or read other abstracts in your field or in the journal where you are submitting your article.

Descriptive abstracts

A descriptive abstract indicates the type of information found in the work. It makes no judgments about the work, nor does it provide results or conclusions of the research. It does incorporate key words found in the text and may include the purpose, methods, and scope of the research. Essentially, the descriptive abstract describes the work being abstracted. Some people consider it an outline of the work, rather than a summary. Descriptive abstracts are usually very short—100 words or less.

Informative abstracts

The majority of abstracts are informative. While they still do not critique or evaluate a work, they do more than describe it. A good informative abstract acts as a surrogate for the work itself. That is, the writer presents and explains all the main arguments and the important results and evidence in the complete article/paper/book. An informative abstract includes the information that can be found in a descriptive abstract (purpose, methods, scope) but also includes the results and conclusions of the research and the recommendations of the author. The length varies according to discipline, but an informative abstract is rarely more than 10% of the length of the entire work. In the case of a longer work, it may be much less.

Here are examples of a descriptive and an informative abstract of this handout on abstracts . Descriptive abstract:

The two most common abstract types—descriptive and informative—are described and examples of each are provided.

Informative abstract:

Abstracts present the essential elements of a longer work in a short and powerful statement. The purpose of an abstract is to provide prospective readers the opportunity to judge the relevance of the longer work to their projects. Abstracts also include the key terms found in the longer work and the purpose and methods of the research. Authors abstract various longer works, including book proposals, dissertations, and online journal articles. There are two main types of abstracts: descriptive and informative. A descriptive abstract briefly describes the longer work, while an informative abstract presents all the main arguments and important results. This handout provides examples of various types of abstracts and instructions on how to construct one.

Which type should I use?

Your best bet in this case is to ask your instructor or refer to the instructions provided by the publisher. You can also make a guess based on the length allowed; i.e., 100-120 words = descriptive; 250+ words = informative.

How do I write an abstract?

The format of your abstract will depend on the work being abstracted. An abstract of a scientific research paper will contain elements not found in an abstract of a literature article, and vice versa. However, all abstracts share several mandatory components, and there are also some optional parts that you can decide to include or not. When preparing to draft your abstract, keep the following key process elements in mind:

• Reason for writing: What is the importance of the research? Why would a reader be interested in the larger work?
• Problem: What problem does this work attempt to solve? What is the scope of the project? What is the main argument/thesis/claim?
• Methodology: An abstract of a scientific work may include specific models or approaches used in the larger study. Other abstracts may describe the types of evidence used in the research.
• Results: Again, an abstract of a scientific work may include specific data that indicates the results of the project. Other abstracts may discuss the findings in a more general way.
• Implications: What changes should be implemented as a result of the findings of the work? How does this work add to the body of knowledge on the topic?

(This list of elements is adapted with permission from Philip Koopman, “How to Write an Abstract.” )

All abstracts include:

• A full citation of the source, preceding the abstract.
• The most important information first.
• The same type and style of language found in the original, including technical language.
• Key words and phrases that quickly identify the content and focus of the work.
• Clear, concise, and powerful language.

Abstracts may include:

• The thesis of the work, usually in the first sentence.
• Background information that places the work in the larger body of literature.
• The same chronological structure as the original work.

How not to write an abstract:

• Do not refer extensively to other works.
• Do not add information not contained in the original work.
• Do not define terms.

If you are abstracting your own writing

When abstracting your own work, it may be difficult to condense a piece of writing that you have agonized over for weeks (or months, or even years) into a 250-word statement. There are some tricks that you could use to make it easier, however.

Reverse outlining:

This technique is commonly used when you are having trouble organizing your own writing. The process involves writing down the main idea of each paragraph on a separate piece of paper– see our short video . For the purposes of writing an abstract, try grouping the main ideas of each section of the paper into a single sentence. Practice grouping ideas using webbing or color coding .

For a scientific paper, you may have sections titled Purpose, Methods, Results, and Discussion. Each one of these sections will be longer than one paragraph, but each is grouped around a central idea. Use reverse outlining to discover the central idea in each section and then distill these ideas into one statement.

Cut and paste:

To create a first draft of an abstract of your own work, you can read through the entire paper and cut and paste sentences that capture key passages. This technique is useful for social science research with findings that cannot be encapsulated by neat numbers or concrete results. A well-written humanities draft will have a clear and direct thesis statement and informative topic sentences for paragraphs or sections. Isolate these sentences in a separate document and work on revising them into a unified paragraph.

If you are abstracting someone else’s writing

When abstracting something you have not written, you cannot summarize key ideas just by cutting and pasting. Instead, you must determine what a prospective reader would want to know about the work. There are a few techniques that will help you in this process:

Identify key terms:

Search through the entire document for key terms that identify the purpose, scope, and methods of the work. Pay close attention to the Introduction (or Purpose) and the Conclusion (or Discussion). These sections should contain all the main ideas and key terms in the paper. When writing the abstract, be sure to incorporate the key terms.

Highlight key phrases and sentences:

Instead of cutting and pasting the actual words, try highlighting sentences or phrases that appear to be central to the work. Then, in a separate document, rewrite the sentences and phrases in your own words.

Don’t look back:

After reading the entire work, put it aside and write a paragraph about the work without referring to it. In the first draft, you may not remember all the key terms or the results, but you will remember what the main point of the work was. Remember not to include any information you did not get from the work being abstracted.

Revise, revise, revise

No matter what type of abstract you are writing, or whether you are abstracting your own work or someone else’s, the most important step in writing an abstract is to revise early and often. When revising, delete all extraneous words and incorporate meaningful and powerful words. The idea is to be as clear and complete as possible in the shortest possible amount of space. The Word Count feature of Microsoft Word can help you keep track of how long your abstract is and help you hit your target length.

Example 1: Humanities abstract

Kenneth Tait Andrews, “‘Freedom is a constant struggle’: The dynamics and consequences of the Mississippi Civil Rights Movement, 1960-1984” Ph.D. State University of New York at Stony Brook, 1997 DAI-A 59/02, p. 620, Aug 1998

This dissertation examines the impacts of social movements through a multi-layered study of the Mississippi Civil Rights Movement from its peak in the early 1960s through the early 1980s. By examining this historically important case, I clarify the process by which movements transform social structures and the constraints movements face when they try to do so. The time period studied includes the expansion of voting rights and gains in black political power, the desegregation of public schools and the emergence of white-flight academies, and the rise and fall of federal anti-poverty programs. I use two major research strategies: (1) a quantitative analysis of county-level data and (2) three case studies. Data have been collected from archives, interviews, newspapers, and published reports. This dissertation challenges the argument that movements are inconsequential. Some view federal agencies, courts, political parties, or economic elites as the agents driving institutional change, but typically these groups acted in response to the leverage brought to bear by the civil rights movement. The Mississippi movement attempted to forge independent structures for sustaining challenges to local inequities and injustices. By propelling change in an array of local institutions, movement infrastructures had an enduring legacy in Mississippi.

Now let’s break down this abstract into its component parts to see how the author has distilled his entire dissertation into a ~200 word abstract.

Example 2: Science Abstract

Luis Lehner, “Gravitational radiation from black hole spacetimes” Ph.D. University of Pittsburgh, 1998 DAI-B 59/06, p. 2797, Dec 1998

The problem of detecting gravitational radiation is receiving considerable attention with the construction of new detectors in the United States, Europe, and Japan. The theoretical modeling of the wave forms that would be produced in particular systems will expedite the search for and analysis of detected signals. The characteristic formulation of GR is implemented to obtain an algorithm capable of evolving black holes in 3D asymptotically flat spacetimes. Using compactification techniques, future null infinity is included in the evolved region, which enables the unambiguous calculation of the radiation produced by some compact source. A module to calculate the waveforms is constructed and included in the evolution algorithm. This code is shown to be second-order convergent and to handle highly non-linear spacetimes. In particular, we have shown that the code can handle spacetimes whose radiation is equivalent to a galaxy converting its whole mass into gravitational radiation in one second. We further use the characteristic formulation to treat the region close to the singularity in black hole spacetimes. The code carefully excises a region surrounding the singularity and accurately evolves generic black hole spacetimes with apparently unlimited stability.

This science abstract covers much of the same ground as the humanities one, but it asks slightly different questions.

How to Write a Biography Statement

How to Write a Professional Biography for a College Student

Biographical statements are more ubiquitous than you may think. While you might have been asked to write one for an academic paper, scholars also write them to accompany published scholarly research. Writers use similar biographical statements on their websites and on their book jackets too. Scholarships, business proposals and other applications may require similar bios as well.

A biographical statement describes the researcher’s or writer’s experience in his field. Biographical statements can include academic awards, degrees earned, research experience and interests.

What Is a Biographical Summary?

A biographical summary is not the same thing as a biographical statement. Biographical summaries are usually longer and contain elements of the writer’s background that are not necessarily relevant to her subject of study. Biographical summaries usually include certain forms of biographical data, such as where the writer was born and in what year. Since biographical summaries are more like shortened third-person biographies, they can even include information about the writer’s personal life, like whether she's married and if she has children. While the purpose of a biographical statement is to express a researcher’s background and accolades in a particular subject, a biographical summary is meant to give information about the person's life and give context to her work.

Don't get confused. There may be some overlap between them. Both a biographical summary and a biographical statement may have information about a person’s research, where she went to school and her academic interests. Both are written in the third person, even when they are written by the researcher herself. Both can even be used on websites and informational materials.

If it helps you to remember, think of a biographical summary as summarizing a whole life. However, a biographical statement (or "bio") states only the necessary information.

How to Write a Bio Statement

When you are writing your own biographical statement, remember to stick to academics. Make a list of your awards and achievements or refer to your CV if you have one. Summarize your interests and explain why you chose this field of study above all others. Don't forget to write in the third person and omit superfluous biographical data. You aren't writing your whole life story.

This task may be difficult if you have not been in academia very long, especially if you are in high school or just beginning your research career. If you’re stumped or you struggle with describing yourself, ask a friend who knows you well to help you. Journaling and free-writing can help too.

If you are in high school, your bio should include information such as your school, if you are specializing in any subject and your plans for the future. Also include any awards you have, like if you won the science fair or if you have perfect attendance. Since you most likely do not have any publications yet, it is permissible to include other biographical elements, such as membership in clubs or achievement in sports. At this point in your academic career, the purpose of this bio is to describe yourself and your interests. Obviously, it will change and grow with you as you continue your studies.

How Do You Write in Third Person?

Biographical statements should be written in the third person. Third person is a point of view in writing that does not use the first-person “I” pronoun. First person feels subjective, whereas writing that is done in the third person seems more objective. Writing in the third person uses the pronouns "he," "she," "they," etc., but when you begin the biographical statement, you will refer to yourself by your full name. Be sure to use whatever form of your name you use on your resume or other published materials. Remember to be consistent. This is the name that will be tied to your research for your whole academic career.

Here is a third-person example: Jane Doe, Ph.D., has a doctorate in astrophysics from the California Institute of Technology. She currently works for SpaceX, where she specializes in fuel dynamics.

What Is Biographical Data?

Biographical data is the kind of information that might be on a driver’s license, such as birthday, address, marital status and more. Most of the time, biographical data is irrelevant to your academic resume, and therefore, it should be omitted from your biographical statement. If you're writing a biographical summary, however, you can include whatever information you deem pertinent.

Biographical Statement Outline

Writing a bio is like writing a well-formed paragraph. It should include a topic sentence, evidence, elaboration and a conclusion. In this type of paragraph, the topic sentence introduces you, the scholar. The body sentences should provide information about your education, work experience and publications. Additional sentences can elaborate on those ideas if you think they need more explaining. If you're stumped on what to write for the conclusion, explain to the reader why you chose this field of study. Why are you so passionate about it? That extra dose of personality will make your bio memorable and unique.

An academic bio can follow the outline below. Depending on the length you’re allowed, you can omit the elaboration sentences.

Start with a topic sentence about yourself. Follow that with a sentence about where you went to school and the degrees you earned. Next, describe your relevant work experience. The sentence after that should list a few of your most prestigious publications. Including more than five publications is unnecessary and sometimes frowned upon. Finally, describe your research interests and why the subject is so important to you. You can also use a lighter detail about yourself if that is acceptable in your field of study.

Topic sentence Education Elaboration on Education Work Experience Elaboration on Work Experience Publications Elaboration on Publications Conclusion

Example Biographical Statement

Here is an example of a biographical statement:

Jane Doe, Ph.D., is a novelist and art critic in Tallahassee, Florida. She has a Ph.D. in rhetoric from Harvard, where she studied the symbolism used in political ads and speeches. Before Harvard, she earned her Master of Fine Arts degree from the University of Iowa. She currently teaches creative nonfiction in the English department of Florida State University. Her latest book, "Untitled," was published by Penguin Random House in 2016. Her essays frequently appear in The New York Times. When she isn’t writing about politics or reading the newspaper, Dr. Doe raises and shows standard poodles with her husband, Clyde.

What Is a Biographical Research Paper?

A biographical research paper is very different from biographical statements and summaries. Biographical statements and summaries are used to share information about yourself. They usually accompany some sort of published material, like a book or research paper.

A biographical research paper, on the other hand, is a short form of biography about another person. Biographical research papers can be written about anyone living or dead, but teachers usually assign this kind of work so students can learn about important historical figures and practice their research skills.

How to Write a Biography About Someone Else

Writing any length of biography, whether it is a biographical research paper or a full-length book, takes a great deal of research and fact checking. To write a biographical research paper, determine the person or historical figure about whom you would like to write. Research him on the internet to figure out what has been written about him already. Figure out a few key elements of his life on which you would like to focus. Read as many articles and books about him as you can. Save quotes and cite them as you’re writing, synthesizing your own story of his life with the information you’ve found.

How to Research for a Biography

If you’re going to write a biography, especially if you want to take on a larger project like a book, you will need to do an immense amount of research. The best biographies are told like stories with characters, action and scenes. Rendering stories like this requires finding first-person accounts that describe the scenes you want to make into a story. When researching a historical figure, the best information for biographies can be found in diaries, letters and other primary sources of that time. Try to find as many sources as you can. If you have multiple sources for one event, you can compare the way they describe the event and use details from all of them to create a more accurate picture. You can also interview scholars who specialize in the person about whom you are writing.

Writing a biography on a living person can be easier in some ways. Talking to that person and interviewing her directly will give you the best information. You can also talk to people who know her and use this information to create a more full picture of her life the same way you would compare diary entries and letters by and about a historical figure.

Either way, as you are researching, be sure to take accurate notes. Not only do you need to write down everything you do, read and discover, you also need to be prepared to quote and cite your sources. Being able to create a full bibliography that cites all of your research is an integral aspect to maintaining the validity of your work. In other words, your bibliography can help you prove that the statements you have written in your biography are true because they’re based on valid primary and secondary sources.

How Do You Write a Bibliography?

To write a bibliography, start with the list of sources you are using to write your biography. If you have copied down their publication information, you already have everything you need to write a bibliography. If you haven’t, you will need to go back and find the following information about each individual source: the source’s title, its author, the city where it was published, the publisher and the year it was published. For sources that are part of a larger work, like an anthology, include the editor of the anthology as well as the title. When you quote specific passages from a book, write down their page numbers. You will need to cite those in the body of your paper. However, if you are writing something longer, like a book, citing page numbers may be unnecessary.

Example Bibliographical Citation

Author’s Surname, Author’s First Name. “Title of Article in Quotations.” Title of Book in Italics. Publisher, publication date, location of publisher. Page numbers.

Citation requirements vary by type of publication. For example, citations of digital publications must include a URL and the access date in addition to the date it was published. Look up specific requirements for different kinds of works or ask your teacher.

You must create a citation entry for everything you read, watch or listen to while researching your biography. Organize entries in alphabetical order by the author's last name on the last page of your report. Title this page “bibliography.” Bibliographies and works cited for longer works will require more than one page.

How to Write an Abstract | Steps & Examples

Published on 1 March 2019 by Shona McCombes . Revised on 10 October 2022 by Eoghan Ryan.

An abstract is a short summary of a longer work (such as a dissertation or research paper ). The abstract concisely reports the aims and outcomes of your research, so that readers know exactly what your paper is about.

Although the structure may vary slightly depending on your discipline, your abstract should describe the purpose of your work, the methods you’ve used, and the conclusions you’ve drawn.

One common way to structure your abstract is to use the IMRaD structure. This stands for:

• Introduction

Abstracts are usually around 100–300 words, but there’s often a strict word limit, so make sure to check the relevant requirements.

In a dissertation or thesis , include the abstract on a separate page, after the title page and acknowledgements but before the table of contents .

Hover over the different parts of the abstract to see how it is constructed.

This paper examines the role of silent movies as a mode of shared experience in the UK during the early twentieth century. At this time, high immigration rates resulted in a significant percentage of non-English-speaking citizens. These immigrants faced numerous economic and social obstacles, including exclusion from public entertainment and modes of discourse (newspapers, theater, radio).

Incorporating evidence from reviews, personal correspondence, and diaries, this study demonstrates that silent films were an affordable and inclusive source of entertainment. It argues for the accessible economic and representational nature of early cinema. These concerns are particularly evident in the low price of admission and in the democratic nature of the actors’ exaggerated gestures, which allowed the plots and action to be easily grasped by a diverse audience despite language barriers.

Keywords: silent movies, immigration, public discourse, entertainment, early cinema, language barriers.

Correct my document today

You will almost always have to include an abstract when:

• Completing a thesis or dissertation
• Submitting a research paper to an academic journal
• Writing a book proposal
• Applying for research grants

It’s easiest to write your abstract last, because it’s a summary of the work you’ve already done. Your abstract should:

• Be a self-contained text, not an excerpt from your paper
• Be fully understandable on its own
• Reflect the structure of your larger work

Start by clearly defining the purpose of your research. What practical or theoretical problem does the research respond to, or what research question did you aim to answer?

You can include some brief context on the social or academic relevance of your topic, but don’t go into detailed background information. If your abstract uses specialised terms that would be unfamiliar to the average academic reader or that have various different meanings, give a concise definition.

After identifying the problem, state the objective of your research. Use verbs like “investigate,” “test,” “analyse,” or “evaluate” to describe exactly what you set out to do.

This part of the abstract can be written in the present or past simple tense  but should never refer to the future, as the research is already complete.

• This study will investigate the relationship between coffee consumption and productivity.
• This study investigates the relationship between coffee consumption and productivity.

Next, indicate the research methods that you used to answer your question. This part should be a straightforward description of what you did in one or two sentences. It is usually written in the past simple tense, as it refers to completed actions.

• Structured interviews will be conducted with 25 participants.
• Structured interviews were conducted with 25 participants.

Don’t evaluate validity or obstacles here — the goal is not to give an account of the methodology’s strengths and weaknesses, but to give the reader a quick insight into the overall approach and procedures you used.

Prevent plagiarism, run a free check.

Next, summarise the main research results . This part of the abstract can be in the present or past simple tense.

• Our analysis has shown a strong correlation between coffee consumption and productivity.
• Our analysis shows a strong correlation between coffee consumption and productivity.
• Our analysis showed a strong correlation between coffee consumption and productivity.

Depending on how long and complex your research is, you may not be able to include all results here. Try to highlight only the most important findings that will allow the reader to understand your conclusions.

Finally, you should discuss the main conclusions of your research : what is your answer to the problem or question? The reader should finish with a clear understanding of the central point that your research has proved or argued. Conclusions are usually written in the present simple tense.

• We concluded that coffee consumption increases productivity.
• We conclude that coffee consumption increases productivity.

If there are important limitations to your research (for example, related to your sample size or methods), you should mention them briefly in the abstract. This allows the reader to accurately assess the credibility and generalisability of your research.

If your aim was to solve a practical problem, your discussion might include recommendations for implementation. If relevant, you can briefly make suggestions for further research.

If your paper will be published, you might have to add a list of keywords at the end of the abstract. These keywords should reference the most important elements of the research to help potential readers find your paper during their own literature searches.

Be aware that some publication manuals, such as APA Style , have specific formatting requirements for these keywords.

It can be a real challenge to condense your whole work into just a couple of hundred words, but the abstract will be the first (and sometimes only) part that people read, so it’s important to get it right. These strategies can help you get started.

Read other abstracts

The best way to learn the conventions of writing an abstract in your discipline is to read other people’s. You probably already read lots of journal article abstracts while conducting your literature review —try using them as a framework for structure and style.

You can also find lots of dissertation abstract examples in thesis and dissertation databases .

Reverse outline

Not all abstracts will contain precisely the same elements. For longer works, you can write your abstract through a process of reverse outlining.

For each chapter or section, list keywords and draft one to two sentences that summarise the central point or argument. This will give you a framework of your abstract’s structure. Next, revise the sentences to make connections and show how the argument develops.

Write clearly and concisely

A good abstract is short but impactful, so make sure every word counts. Each sentence should clearly communicate one main point.

To keep your abstract or summary short and clear:

• Avoid passive sentences: Passive constructions are often unnecessarily long. You can easily make them shorter and clearer by using the active voice.
• Avoid long sentences: Substitute longer expressions for concise expressions or single words (e.g., “In order to” for “To”).
• Avoid obscure jargon: The abstract should be understandable to readers who are not familiar with your topic.
• Avoid repetition and filler words: Replace nouns with pronouns when possible and eliminate unnecessary words.
• Avoid detailed descriptions: An abstract is not expected to provide detailed definitions, background information, or discussions of other scholars’ work. Instead, include this information in the body of your thesis or paper.

If you’re struggling to edit down to the required length, you can get help from expert editors with Scribbr’s professional proofreading services .

Check your formatting

If you are writing a thesis or dissertation or submitting to a journal, there are often specific formatting requirements for the abstract—make sure to check the guidelines and format your work correctly. For APA research papers you can follow the APA abstract format .

Checklist: Abstract

The word count is within the required length, or a maximum of one page.

The abstract appears after the title page and acknowledgements and before the table of contents .

I have clearly stated my research problem and objectives.

I have briefly described my methodology .

I have summarized the most important results .

I have stated my main conclusions .

I have mentioned any important limitations and recommendations.

The abstract can be understood by someone without prior knowledge of the topic.

You've written a great abstract! Use the other checklists to continue improving your thesis or dissertation.

An abstract is a concise summary of an academic text (such as a journal article or dissertation ). It serves two main purposes:

• To help potential readers determine the relevance of your paper for their own research.
• To communicate your key findings to those who don’t have time to read the whole paper.

Abstracts are often indexed along with keywords on academic databases, so they make your work more easily findable. Since the abstract is the first thing any reader sees, it’s important that it clearly and accurately summarises the contents of your paper.

An abstract for a thesis or dissertation is usually around 150–300 words. There’s often a strict word limit, so make sure to check your university’s requirements.

The abstract is the very last thing you write. You should only write it after your research is complete, so that you can accurately summarize the entirety of your thesis or paper.

Avoid citing sources in your abstract . There are two reasons for this:

• The abstract should focus on your original research, not on the work of others.
• The abstract should be self-contained and fully understandable without reference to other sources.

There are some circumstances where you might need to mention other sources in an abstract: for example, if your research responds directly to another study or focuses on the work of a single theorist. In general, though, don’t include citations unless absolutely necessary.

The abstract appears on its own page, after the title page and acknowledgements but before the table of contents .

Getting a paper out there is great. Getting the words on the paper can be painful. Here is an easy manual for how to write an abstract that requires minimal effort.

The purpose of an abstract is to spark the reader’s interest in the story and motivate them to continue reading the whole paper. It might be obvious, but it is worth pointing out that people only cite your work if they have read it. A compelling writing style is a first step in that direction because a well-written paper is more likely to have a large readership.

Consider an abstract a 5-part structure consisting of 1) introduction, 2) problem/objective, 3) “Here we show”, 4) main results & conclusions, and 5) implications.

1) Introduction (2 sentences):

    --> Sentence 1: Basic introduction to the field; accessible to scientists of any  discipline.

    --> Sentence 2: Background of the specific research question; comprehensible to scientists in the same or closely related fields of research.

2) Problem/objective (1 sentence):

    --> Explanation what is missing/unknown/problematic, i.e. why the current study happened. Typically, this sentence starts with “However”.

3) “Here we show” (1 sentence):

    --> The main result/key finding summarised in one sentence, which starts with “Here we show”.

4) Main results and conclusions (~ 3 – 5 sentences)

    --> Summary of the most important findings of the study that are the foundation of the main conclusions. A few key bits of data are welcome but adding too many numbers is off-putting to the reader. Keep it focussed.

    --> Unless the method is new and/or a main part of the paper, there’s no need to include any details in the abstract. If you mentioned, it should be included in a sentence along the lines of “Using xyz, we show that (…)”.

5) Implications (1 – 2 sentences)

    --> Some explanation on how your findings advance the field. Where does your work lead and what are the immediate implications? The word “immediate” is key here because being too creative or hyping the work are pitfalls that should be avoided. Rather, keep it realistic and explain which opportunities your work offer and/or what it leads to.

If you hit the five marks above in exactly this order, your abstract is likely to tell a compelling story. Of course, there are also some journal-specific formatting requirements for your abstract. For instance, for Nature Communications those are: 150 words max., no references or unnecessary abbreviations/acronyms, and the results should be presented in the present tense.

The target audience

One last piece of advice: When writing the abstract and, in fact, your whole paper, consider your ultimate audience, which are active scientists not editors. Getting published is only the first step. Eventually, your paper is supposed to attract as many readers as possible so it gets the exposure and attention it deserves.

Further writing advice and courses

Of course, there is much more to writing a compelling paper, and I might write further posts on this matter. For those who would like to boost their skills in scientific writing and better understand how to navigate the publishing system, Springer Nature offers Nature Masterclasses which include face-to-face workshops , webinars , and online training courses (free sample here and free online course “Focus on Peer Review” here ).

Using non verbal cues to build rapport with students, emotionally challenging research and researcher well-being, augmenting the doctoral thesis in preparation for a viva, how hard can it be testing ai detection tools.

Writing an abstract might not seem to be at the top of your list of priorities when writing your PhD dissertation , but it’s probably the first thing a reader will see when they encounter your research, so it’s worth putting the effort in to get it right. Here are some ways to make it sing. 

What is an abstract?

An abstract is a concise overview of an extensive piece of research work such as a thesis, dissertation or research paper. Depending on the discipline, it usually contains the purpose of the research, the methodologies employed and the conclusions derived. Abstracts typically range from 500 to 800 words and appear on a separate page after the title page and acknowledgements, but preceding the table of contents. Although it might be tempting to start your thesis by drafting your abstract, I advise postponing until you’ve completed a first draft so that you ensure you cover all topics discussed in your thesis.

What to include in your abstract

Purpose of the study.

Begin your abstract by concisely defining the problems your study addresses or outlining the gaps in knowledge it fills. It should provide the reader with new and useful information regarding your research in the present or past tense. Use verbs such as “test”, “evaluate” and “analyse” to make the research objective specific, measurable, attainable and time-bound. Avoid providing detailed background information and personal opinions at this stage.

In this part of your abstract, explain how you designed and conducted your research and how it addresses your research questions in the past tense. The aim here is to give the reader a prompt insight into your approach, not to evaluate challenges, validity and reliability. Highlight the samples you used and the data collection and analysis tools you employed. 

• Campus resource collection: What I wish I’d known about academia
• Campus resource collection: Resources on academic writing
• What is your academic writing temperament?

Results and conclusion

Summarise and highlight the most significant findings that will allow the reader to understand the conclusions in the present or past tense. At the end of your abstract, the reader ought to have a firm grasp of the main argument. If the motive of the research is to resolve a real-world issue, you can include practical implications and suggestions in the findings. Briefly offer future recommendations for further research, if applicable. 

When writing your abstract, imagine who might read your research; a curious reader, not necessarily an expert in the field, expects the information to be accessible and not overly complex. 

Tips on how to write an abstract for a research paper

• Explain why you chose this area of research and the significance of the study
• Ask yourself “why?” “what?” “how?” and “so what?” and use the abstract to address these questions. 
• Highlight the novelty of your research 
• Explain how your research adds to the existing body of literature on the topic
• Explain your research design, highlighting elements such as approach, demographics, sampling and geographical information
• Explain how your research is relevant and significant
• Address practical implications to potential interested parties – for example, any issues relating to policy 
• Avoid technical jargon, generalised statements and vague claims that make your work difficult to read
• Avoid acronyms and abbreviations at this stage. Add them into the introduction instead 
• Provide concise, consistent and accurate details
• Adhere to the word count limit specified in your instructions
• Include essential keywords for search engine optimisation
• There’s no need to include references at this stage
• Never copy and paste content directly from elsewhere in the thesis; use new vocabulary and phrases to differentiate the abstract from the rest of the text.

These tips will help to make the abstract writing process smoother, allowing you to make a good first impression on whoever comes across your work when you’re ready to send it out into the world.

How to Write a Speaker Bio for a Conference (with Examples)

Published on 28 Jul 2022

Author bios, or speaker bios, can be used for a variety of purposes. They can be included as part of your application to present at a conference or posted to an event website to introduce yourself as a presenter at the event. Bios can also be helpful to have on your profile in the participant directory of the conference management tool used for the event, so that others to know what you’re working on. 

For many, an author bio is their first introduction to their peers – sort of like a digital, written handshake. In the world of academic conferences, conference programmes and websites will include a biography of every speaker.

An interesting, engaging bio can help encourage others to participate in the event, and impact the number of people who attend your presentation, so it’s important to take your time, do your research, and write a biography that will highlight the characteristics that set you apart from the rest. 

How do you write a good short bio?

Start by taking notes of your strengths and accomplishments. Look at your CV and pull out the very basics like where you went to school and your primary area of interest, then add in the impressive details like fellowships, published pieces, or exciting collaborations.

Here are the detailed steps to take to write a bio that will inspire your peers to attend your presentation or connect with you in a breakout session.

Step 1: Find out the required length

When you’re writing a speaker bio for a specific conference, make sure you know the length of bio the organizer is looking for. Each conference will have its own guidelines, and some will even ask for two versions – a longer one for the event website and a shorter one for the printed program. 

Step 2. Write in the third person

Write your bio as if you’re writing it about someone else. Not only is this the most common format for a speaker biography, but it gives you the opportunity to add many details of your success and experiences without coming across as pompous or arrogant. Writing in the third person gives some authors more confidence to speak about themselves and their accomplishments. 

Start out with your full name, then decide whether to refer to yourself throughout using your first name or last name. For less formal events, using your first name creates an air of familiarity, while referring to yourself by your last name is more professional and formal. 

Step 3: Make a list of the basics

There are basic pieces of information that should be included in every speaker's biography.

• Your full name
• Your credentials
• Where you completed your graduate studies
• Your current position and where you work
• Your areas of interest
• How your experience is relevant and beneficial to the focus of the event
• Your most notable accomplishments - avoid building a laundry-list of published pieces, focus on the most impressive
• If you’ve published in any top peer-reviewed journals like Science, Nature, or the equivalent for your field, be sure to include this 
• List any patents you hold or any breakthrough findings
• Note any impressive research collaborations with well-known subject matter experts

Step 4: Write to your audience

Get to know your audience before you start writing. I don’t mean get to know them personally – that will happen at the event. I mean get an understanding of the demographics and areas of interest of the potential conference attendees that will be reading your bio. 

If you’re presenting at an ornithology conference and your audience is passionate about hands-on research, focus the content of your bio more heavily towards your applied experience studying birds. You can do this by highlighting the hands-on research you’ve done rather than the degrees and certifications you’ve earned. In this example, when discussing your PhD thesis, you would focus on the part of your research that led you to travel to Antarctica to study the Wandering Albatross migration. 

If your audience is made up primarily of institutional academics, highlight who funded your research and which institutions you were collaborating with when the work was being conducted. For example, focus the mention of your PhD thesis around the fact that you studied at UCLA under one of their many renowned Professors of Ecology and Evolutionary Biology. 

Step 5: Add some personality

One way to set yourself apart from other speakers is to inject some fun into your bio. You want it to be interesting and engaging – that’s how you will encourage other conference attendees to read the biography from start to finish. Don’t be afraid to try out some wordplay or alliterations. While there are great bios that start out with the speaker’s primary research area, some of the most engaging bios start off with a sentence or statement that is bold, unexpected, and captures your reader’s attention. 

Examples of speakers' bio

Here are two good examples of the type of speaker’s biographies you’ll find on conference websites and programs. 

Brandon Farbstein

Brandon Farbstein’s bio is short, it’s interesting, and it opens with information that highlights the attributes that set him apart from other speakers. It gets personal and draws the reader in. Personally, if I saw this bio in a conference program I would definitely make time in my schedule to attend this presentation. 

“At just 20, Brandon Farbstein has already made a name for himself worldwide as a sought-after speaker and prominent Gen Z activist. Diagnosed with a rare form of dwarfism at the age of 2, Brandon stands at 3’9” – making his life’s journey full of adversity, strength, and impact. After feeling invisible and without a purpose for the first 15 years of his life, he discovered his calling on the TEDx stage, and suddenly realized his life’s meaning: to change the lens through which people see their world.  In just three years of speaking, over five million people across the globe have been inspired by Brandon; and his work continues to touch audiences from every walk of life.”

One notable thing lacking here is clear information about Brandon’s work. We know a lot about him personally, we know that he’s a TEDx speaker, and we know that his work has impacted millions of people, but we really don’t know what he actually does. 

Nicole Redvers

Nicole Redvers' bio starts by identifying her personal connection to her field of study, peaking the interest of readers and making it clear that she is passionate about her work. She goes on to cover her specific area of research, the institutions she’s connected with, and the advocacy works she’s involved with to advance her research in a way that will improve the lives of others. 

“Dr. Nicole Redvers, ND, MPH, is a member of the Deninu K’ue First Nation in Denendeh (NWT) and has worked with Indigenous patients, scholars, and communities around the globe her entire career. She is an assistant professor in the Department of Family and Community Medicine and the Department of Indigenous Health at the University of North Dakota where she helped develop and launch the first Indigenous health PhD program. Dr. Redvers is co-founder and current board chair of the Canadian charity the Arctic Indigenous Wellness Foundation based in Yellowknife, NWT, providing traditional Indigenous-rooted Land-based wellness supports to northerners. She has been actively involved at regional, national, and international levels promoting the inclusion of Indigenous perspectives in both human and planetary health research and practice. She is author of the trade paperback book titled, ‘The Science of the Sacred: Bridging Global Indigenous Medicine Systems and Modern Scientific Principles’.”

One thing I like about this bio is that it takes the reader through a logical flow of information that ends with Redvers’ most notable accomplishments. 

A good speaker's bio is short, direct, and sparks interest. It provides the speaker with an opportunity to connect with conference attendees before the event begins, and it provides event attendees with an introduction to the speakers presenting at the event which will help them determine which presentations they want to attend.

With the instructions we provided and half an hour of your time, you’ll have a bio that stands out from the rest!

How to write a killer abstract in 10 sentences

The experiments were carefully designed. The data have been meticulously collected. The figures have been expertly prepared. The results are beautiful! All that stands between you and presenting your science at the American Society for Biochemistry and Molecular Biology 2022 annual meeting is writing an abstract. But where do you begin? How do you write an abstract that will get your science noticed? 

Each day, we are bombarded with a deluge of information, each item vying for our attention. We rely on eye-catching headlines to draw us toward the content that might enrich our lives. In the scientific arena, we rely on abstracts to provide snapshots of studies that may be relevant to us. Abstracts are a crucial filter that helps us to gauge quickly which reports must go to the top of our to-read list. 

Previously, I’ve written how to present a killer research seminar by pretending you are serving the audience a three-course meal at a mystery dinner theater. The appetizer introduces the scientific puzzle as a mystery. The main course is composed of the experiments that uncovered clues. The dessert course satisfies the audience by revealing how the clues addressed the mystery.

Below, I outline how this formula can be adapted to craft an irresistible abstract that will make people hungry to see more of your work. 

Sentences 1-2. Set the stage.

The beginning of a killer abstract must convey the scientific question that keeps you up at night and why. Use the first couple of sentences to describe succinctly the most salient features of the phenomenon you are investigating and, if applicable, how it is relevant to a medical or environmental problem. The stage you set should draw attention to a gap in our knowledge that you are attempting to fill. 

Sentence 3. State the mystery.

The next sentence is a clear and focused hypothesis framed as a question — this represents the mystery your study aims to solve. It should be an interesting and intuitive question derived from the background information in your introductory sentences. If the reader cannot guess your hypothesis after reading that introduction, you haven’t set the stage well enough.

Sentences 4-8. Describe your detective work.

This section is the heart of the experimental effort you used to gather clues relating to the mystery. Explain the case as Sherlock would to Watson, concisely mentioning the rationale and techniques used to unearth the clues. 

Like discriminating detectives, scientists demand precision. If you are vague, your poor reader is forced to wonder what you mean. For example, the statement “Transcript levels were greatly altered in the knockout” leaves people with questions: How many transcripts? How were they altered, and by how much? Instead, write, “We determined that 75% of transcripts increased twofold or more in the knockout.” 

You do not want to disrupt a compelling story by going off on distracting tangents. You need not mention every experiment you completed, only those that provide the most important clues needed to answer the question. 

Sentence 9. Solving the mystery.  

This is the sentence the audience has been waiting for, but if you’ve laid out the clues adequately, they should be able to deduce the conclusion themselves. This sentence should state clearly how your findings contribute to solving the mystery you posed in the introduction.

It is important to note that you don’t need to solve the mystery completely to make a compelling story. Negative data or replicative studies are vital to the scientific enterprise, providing critical clues for resolving biological questions. 

Sentence 10. So what?  

The final sentence of your abstract should remind the reader why your findings are important — for example, in terms of providing new insights into behavior, mitochondrial function or gene expression. If applicable, mention how these findings may facilitate the development of new therapies for a disease. 

In summary, a killer abstract tells a story by framing your scientific study as a mystery. As with all good stories, you’ll also want to devise an alluring or clever title to capture attention. 

Remember: Conference organizers and participants have many abstracts on their plates. Be sympathetic to their plight and make yours enticing and easy to digest. You can keep it simple by avoiding technical jargon wherever possible, defining esoteric terms that must be used, and eliminating unnecessary words or phrases. Avoid the temptation to add extraneous information or research results that are superfluous to your story.

Finally, take advantage of the many resources available to assist writers. Be sure to use tools for checking spelling and grammar. Make certain that you include relevant keywords in your abstract; many people use them to scan the abstract book. 

And don’t forget the most important resource of all — readers. Don’t submit an abstract before taking it on a few test spins by getting others inside and outside your field to read it. If they are not intrigued, you need to go back to the kitchen and cook up a better dish.

How To Write A Lab Report | Step-by-Step Guide & Examples

Published on May 20, 2021 by Pritha Bhandari . Revised on July 23, 2023.

A lab report conveys the aim, methods, results, and conclusions of a scientific experiment. The main purpose of a lab report is to demonstrate your understanding of the scientific method by performing and evaluating a hands-on lab experiment. This type of assignment is usually shorter than a research paper .

Lab reports are commonly used in science, technology, engineering, and mathematics (STEM) fields. This article focuses on how to structure and write a lab report.

Structuring a lab report, introduction, other interesting articles, frequently asked questions about lab reports.

The sections of a lab report can vary between scientific fields and course requirements, but they usually contain the purpose, methods, and findings of a lab experiment .

Each section of a lab report has its own purpose.

• Title: expresses the topic of your study
• Abstract : summarizes your research aims, methods, results, and conclusions
• Introduction: establishes the context needed to understand the topic
• Method: describes the materials and procedures used in the experiment
• Results: reports all descriptive and inferential statistical analyses
• Discussion: interprets and evaluates results and identifies limitations
• Conclusion: sums up the main findings of your experiment
• References: list of all sources cited using a specific style (e.g. APA )
• Appendices : contains lengthy materials, procedures, tables or figures

Although most lab reports contain these sections, some sections can be omitted or combined with others. For example, some lab reports contain a brief section on research aims instead of an introduction, and a separate conclusion is not always required.

If you’re not sure, it’s best to check your lab report requirements with your instructor.

Your title provides the first impression of your lab report – effective titles communicate the topic and/or the findings of your study in specific terms.

Create a title that directly conveys the main focus or purpose of your study. It doesn’t need to be creative or thought-provoking, but it should be informative.

• The effects of varying nitrogen levels on tomato plant height.
• Testing the universality of the McGurk effect.
• Comparing the viscosity of common liquids found in kitchens.

An abstract condenses a lab report into a brief overview of about 150–300 words. It should provide readers with a compact version of the research aims, the methods and materials used, the main results, and the final conclusion.

Think of it as a way of giving readers a preview of your full lab report. Write the abstract last, in the past tense, after you’ve drafted all the other sections of your report, so you’ll be able to succinctly summarize each section.

To write a lab report abstract, use these guiding questions:

• What is the wider context of your study?
• What research question were you trying to answer?
• How did you perform the experiment?
• What did your results show?
• How did you interpret your results?
• What is the importance of your findings?

Nitrogen is a necessary nutrient for high quality plants. Tomatoes, one of the most consumed fruits worldwide, rely on nitrogen for healthy leaves and stems to grow fruit. This experiment tested whether nitrogen levels affected tomato plant height in a controlled setting. It was expected that higher levels of nitrogen fertilizer would yield taller tomato plants.

Levels of nitrogen fertilizer were varied between three groups of tomato plants. The control group did not receive any nitrogen fertilizer, while one experimental group received low levels of nitrogen fertilizer, and a second experimental group received high levels of nitrogen fertilizer. All plants were grown from seeds, and heights were measured 50 days into the experiment.

The effects of nitrogen levels on plant height were tested between groups using an ANOVA. The plants with the highest level of nitrogen fertilizer were the tallest, while the plants with low levels of nitrogen exceeded the control group plants in height. In line with expectations and previous findings, the effects of nitrogen levels on plant height were statistically significant. This study strengthens the importance of nitrogen for tomato plants.

Your lab report introduction should set the scene for your experiment. One way to write your introduction is with a funnel (an inverted triangle) structure:

• Start with the broad, general research topic
• Narrow your topic down your specific study focus
• End with a clear research question

Begin by providing background information on your research topic and explaining why it’s important in a broad real-world or theoretical context. Describe relevant previous research on your topic and note how your study may confirm it or expand it, or fill a gap in the research field.

This lab experiment builds on previous research from Haque, Paul, and Sarker (2011), who demonstrated that tomato plant yield increased at higher levels of nitrogen. However, the present research focuses on plant height as a growth indicator and uses a lab-controlled setting instead.

Next, go into detail on the theoretical basis for your study and describe any directly relevant laws or equations that you’ll be using. State your main research aims and expectations by outlining your hypotheses .

Based on the importance of nitrogen for tomato plants, the primary hypothesis was that the plants with the high levels of nitrogen would grow the tallest. The secondary hypothesis was that plants with low levels of nitrogen would grow taller than plants with no nitrogen.

Your introduction doesn’t need to be long, but you may need to organize it into a few paragraphs or with subheadings such as “Research Context” or “Research Aims.”

A lab report Method section details the steps you took to gather and analyze data. Give enough detail so that others can follow or evaluate your procedures. Write this section in the past tense. If you need to include any long lists of procedural steps or materials, place them in the Appendices section but refer to them in the text here.

You should describe your experimental design, your subjects, materials, and specific procedures used for data collection and analysis.

Experimental design

Briefly note whether your experiment is a within-subjects  or between-subjects design, and describe how your sample units were assigned to conditions if relevant.

A between-subjects design with three groups of tomato plants was used. The control group did not receive any nitrogen fertilizer. The first experimental group received a low level of nitrogen fertilizer, while the second experimental group received a high level of nitrogen fertilizer.

Describe human subjects in terms of demographic characteristics, and animal or plant subjects in terms of genetic background. Note the total number of subjects as well as the number of subjects per condition or per group. You should also state how you recruited subjects for your study.

List the equipment or materials you used to gather data and state the model names for any specialized equipment.

List of materials

35 Tomato seeds

15 plant pots (15 cm tall)

Light lamps (50,000 lux)

Nitrogen fertilizer

Measuring tape

Describe your experimental settings and conditions in detail. You can provide labelled diagrams or images of the exact set-up necessary for experimental equipment. State how extraneous variables were controlled through restriction or by fixing them at a certain level (e.g., keeping the lab at room temperature).

Light levels were fixed throughout the experiment, and the plants were exposed to 12 hours of light a day. Temperature was restricted to between 23 and 25℃. The pH and carbon levels of the soil were also held constant throughout the experiment as these variables could influence plant height. The plants were grown in rooms free of insects or other pests, and they were spaced out adequately.

Your experimental procedure should describe the exact steps you took to gather data in chronological order. You’ll need to provide enough information so that someone else can replicate your procedure, but you should also be concise. Place detailed information in the appendices where appropriate.

In a lab experiment, you’ll often closely follow a lab manual to gather data. Some instructors will allow you to simply reference the manual and state whether you changed any steps based on practical considerations. Other instructors may want you to rewrite the lab manual procedures as complete sentences in coherent paragraphs, while noting any changes to the steps that you applied in practice.

If you’re performing extensive data analysis, be sure to state your planned analysis methods as well. This includes the types of tests you’ll perform and any programs or software you’ll use for calculations (if relevant).

First, tomato seeds were sown in wooden flats containing soil about 2 cm below the surface. Each seed was kept 3-5 cm apart. The flats were covered to keep the soil moist until germination. The seedlings were removed and transplanted to pots 8 days later, with a maximum of 2 plants to a pot. Each pot was watered once a day to keep the soil moist.

The nitrogen fertilizer treatment was applied to the plant pots 12 days after transplantation. The control group received no treatment, while the first experimental group received a low concentration, and the second experimental group received a high concentration. There were 5 pots in each group, and each plant pot was labelled to indicate the group the plants belonged to.

50 days after the start of the experiment, plant height was measured for all plants. A measuring tape was used to record the length of the plant from ground level to the top of the tallest leaf.

In your results section, you should report the results of any statistical analysis procedures that you undertook. You should clearly state how the results of statistical tests support or refute your initial hypotheses.

The main results to report include:

• any descriptive statistics
• statistical test results
• the significance of the test results
• estimates of standard error or confidence intervals

The mean heights of the plants in the control group, low nitrogen group, and high nitrogen groups were 20.3, 25.1, and 29.6 cm respectively. A one-way ANOVA was applied to calculate the effect of nitrogen fertilizer level on plant height. The results demonstrated statistically significant ( p = .03) height differences between groups.

Next, post-hoc tests were performed to assess the primary and secondary hypotheses. In support of the primary hypothesis, the high nitrogen group plants were significantly taller than the low nitrogen group and the control group plants. Similarly, the results supported the secondary hypothesis: the low nitrogen plants were taller than the control group plants.

These results can be reported in the text or in tables and figures. Use text for highlighting a few key results, but present large sets of numbers in tables, or show relationships between variables with graphs.

You should also include sample calculations in the Results section for complex experiments. For each sample calculation, provide a brief description of what it does and use clear symbols. Present your raw data in the Appendices section and refer to it to highlight any outliers or trends.

The Discussion section will help demonstrate your understanding of the experimental process and your critical thinking skills.

In this section, you can:

• Interpret your results
• Compare your findings with your expectations
• Identify any sources of experimental error
• Explain any unexpected results
• Suggest possible improvements for further studies

Interpreting your results involves clarifying how your results help you answer your main research question. Report whether your results support your hypotheses.

• Did you measure what you sought out to measure?
• Were your analysis procedures appropriate for this type of data?

Compare your findings with other research and explain any key differences in findings.

• Are your results in line with those from previous studies or your classmates’ results? Why or why not?

An effective Discussion section will also highlight the strengths and limitations of a study.

• Did you have high internal validity or reliability?
• How did you establish these aspects of your study?

When describing limitations, use specific examples. For example, if random error contributed substantially to the measurements in your study, state the particular sources of error (e.g., imprecise apparatus) and explain ways to improve them.

The results support the hypothesis that nitrogen levels affect plant height, with increasing levels producing taller plants. These statistically significant results are taken together with previous research to support the importance of nitrogen as a nutrient for tomato plant growth.

However, unlike previous studies, this study focused on plant height as an indicator of plant growth in the present experiment. Importantly, plant height may not always reflect plant health or fruit yield, so measuring other indicators would have strengthened the study findings.

Another limitation of the study is the plant height measurement technique, as the measuring tape was not suitable for plants with extreme curvature. Future studies may focus on measuring plant height in different ways.

The main strengths of this study were the controls for extraneous variables, such as pH and carbon levels of the soil. All other factors that could affect plant height were tightly controlled to isolate the effects of nitrogen levels, resulting in high internal validity for this study.

Your conclusion should be the final section of your lab report. Here, you’ll summarize the findings of your experiment, with a brief overview of the strengths and limitations, and implications of your study for further research.

Some lab reports may omit a Conclusion section because it overlaps with the Discussion section, but you should check with your instructor before doing so.

A lab report conveys the aim, methods, results, and conclusions of a scientific experiment . Lab reports are commonly assigned in science, technology, engineering, and mathematics (STEM) fields.

The purpose of a lab report is to demonstrate your understanding of the scientific method with a hands-on lab experiment. Course instructors will often provide you with an experimental design and procedure. Your task is to write up how you actually performed the experiment and evaluate the outcome.

In contrast, a research paper requires you to independently develop an original argument. It involves more in-depth research and interpretation of sources and data.

A lab report is usually shorter than a research paper.

The sections of a lab report can vary between scientific fields and course requirements, but it usually contains the following:

• Abstract: summarizes your research aims, methods, results, and conclusions
• References: list of all sources cited using a specific style (e.g. APA)
• Appendices: contains lengthy materials, procedures, tables or figures

The results chapter or section simply and objectively reports what you found, without speculating on why you found these results. The discussion interprets the meaning of the results, puts them in context, and explains why they matter.

In qualitative research , results and discussion are sometimes combined. But in quantitative research , it’s considered important to separate the objective results from your interpretation of them.

Reference Examples

More than 100 reference examples and their corresponding in-text citations are presented in the seventh edition Publication Manual . Examples of the most common works that writers cite are provided on this page; additional examples are available in the Publication Manual .

To find the reference example you need, first select a category (e.g., periodicals) and then choose the appropriate type of work (e.g., journal article ) and follow the relevant example.

When selecting a category, use the webpages and websites category only when a work does not fit better within another category. For example, a report from a government website would use the reports category, whereas a page on a government website that is not a report or other work would use the webpages and websites category.

Also note that print and electronic references are largely the same. For example, to cite both print books and ebooks, use the books and reference works category and then choose the appropriate type of work (i.e., book ) and follow the relevant example (e.g., whole authored book ).

Examples on these pages illustrate the details of reference formats. We make every attempt to show examples that are in keeping with APA Style’s guiding principles of inclusivity and bias-free language. These examples are presented out of context only to demonstrate formatting issues (e.g., which elements to italicize, where punctuation is needed, placement of parentheses). References, including these examples, are not inherently endorsements for the ideas or content of the works themselves. An author may cite a work to support a statement or an idea, to critique that work, or for many other reasons. For more examples, see our sample papers .
