What Is the Difference Between an Abstract and a Thesis Statement?

How to Write a Thesis & Introduction for a Critical Reflection Essay

How to Write a Thesis & Introduction for a Critical Reflection Essay

College assignments, specifically the requirements when writing papers, can cause confusion for new students. Both forms of relaying information are utilized for different reasons but can be found within the same writing piece on occasion. Understanding the difference between two formats of information such as an abstract and thesis statement is important in professional writing at the college level. A strong thesis statement allows the reader to know what the stance of the writer is before reading through the full paper. An abstract allows the reader to understand at a glance what the full article is about.

An abstract is a short body of writing that is used to summarize a longer piece of writing. A dissertation for a doctoral program contains an abstract. The abstract information varies on the discipline that the writing addresses. In 1997, Philip Koopman from Carnegie Mellon University highlighted common considerations of an abstract to include the motivation, approach, problem statement, results and conclusion summarized into a brief document. The abstract is used to index the larger work or to simply describe the larger work. Abstracts allow researchers or readers to grasp the overall content of the full piece of writing within a paragraph or two.

Thesis Statement

A thesis statement is a claim by the writer that can be argued or disputed by others. The statement is typically one sentence but may contain more in rare circumstances. The sentence(s) will describe what the writer wants to specifically discuss about the central topic. The rule of thumb is not to state a fact but to take a position regarding the facts. Thesis statements appear in a variety of writing pieces from small writing assignments within a college course or a major submission for degree requirements.

Similarities

Although the thesis statement and abstract are different entities, they share a number of similarities. John December and Susan Katz who wrote for the Rensselaer Writing Center and the University of North Carolina highlight that both the abstract and thesis statement should be written after the significant body of the paper is complete. Both require significant research and consideration before formulation. It is also not uncommon to find both a thesis statement and abstract within the same writing piece.

Differences

The significant difference between an abstract and a thesis statement is the purpose behind each. While the abstract summarizes the important aspects of a complete writing piece, the thesis statement lays out only the position a writer is offering within the document. The abstract is longer in length and contains at least five factors regarding the writing it introduces. The thesis statement is short and contains one significant piece of information to inform the reader.

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.

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.

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. . .”).

Reporting new findings about the reasons for increasing economic homogamy among spouses

Gonalons-Pons, Pilar, and Christine R. Schwartz. “Trends in Economic Homogamy: Changes in Assortative Mating or the Division of Labor in Marriage?” Demography , vol. 54, no. 3, 2017, pp. 985-1005.

“The growing economic resemblance of spouses has contributed to rising inequality by increasing the number of couples in which there are two high- or two low-earning partners. [Annotation for the previous sentence: The first sentence introduces the topic under study (the “economic resemblance of spouses”). This sentence also implies the question underlying this research study: what are the various causes—and the interrelationships among them—for this trend?] The dominant explanation for this trend is increased assortative mating. Previous research has primarily relied on cross-sectional data and thus has been unable to disentangle changes in assortative mating from changes in the division of spouses’ paid labor—a potentially key mechanism given the dramatic rise in wives’ labor supply. [Annotation for the previous two sentences: These next two sentences explain what previous research has demonstrated. By pointing out the limitations in the methods that were used in previous studies, they also provide a rationale for new research.] We use data from the Panel Study of Income Dynamics (PSID) to decompose the increase in the correlation between spouses’ earnings and its contribution to inequality between 1970 and 2013 into parts due to (a) changes in assortative mating, and (b) changes in the division of paid labor. [Annotation for the previous sentence: The data, research and analytical methods used in this new study.] Contrary to what has often been assumed, the rise of economic homogamy and its contribution to inequality is largely attributable to changes in the division of paid labor rather than changes in sorting on earnings or earnings potential. Our findings indicate that the rise of economic homogamy cannot be explained by hypotheses centered on meeting and matching opportunities, and they show where in this process inequality is generated and where it is not.” (p. 985) [Annotation for the previous two sentences: The major findings from and implications and significance of this study.]

Analyzing underground pulp fiction publications in Tanzania, this article makes an argument about the cultural significance of those publications

Emily Callaci. “Street Textuality: Socialism, Masculinity, and Urban Belonging in Tanzania’s Pulp Fiction Publishing Industry, 1975-1985.” Comparative Studies in Society and History , vol. 59, no. 1, 2017, pp. 183-210.

“From the mid-1970s through the mid-1980s, a network of young urban migrant men created an underground pulp fiction publishing industry in the city of Dar es Salaam. [Annotation for the previous sentence: The first sentence introduces the context for this research and announces the topic under study.] As texts that were produced in the underground economy of a city whose trajectory was increasingly charted outside of formalized planning and investment, these novellas reveal more than their narrative content alone. These texts were active components in the urban social worlds of the young men who produced them. They reveal a mode of urbanism otherwise obscured by narratives of decolonization, in which urban belonging was constituted less by national citizenship than by the construction of social networks, economic connections, and the crafting of reputations. This article argues that pulp fiction novellas of socialist era Dar es Salaam are artifacts of emergent forms of male sociability and mobility. In printing fictional stories about urban life on pilfered paper and ink, and distributing their texts through informal channels, these writers not only described urban communities, reputations, and networks, but also actually created them.” (p. 210) [Annotation for the previous sentences: The remaining sentences in this abstract interweave other essential information for an abstract for this article. The implied research questions: What do these texts mean? What is their historical and cultural significance, produced at this time, in this location, by these authors? The argument and the significance of this analysis in microcosm: these texts “reveal a mode or urbanism otherwise obscured . . .”; and “This article argues that pulp fiction novellas. . . .” This section also implies what previous historical research has obscured. And through the details in its argumentative claims, this section of the abstract implies the kinds of methods the author has used to interpret the novellas and the concepts under study (e.g., male sociability and mobility, urban communities, reputations, network. . . ).]

“Several studies have reported reprogramming of fibroblasts into induced cardiomyocytes; however, reprogramming into proliferative induced cardiac progenitor cells (iCPCs) remains to be accomplished. [Annotation for the previous sentence: The first sentence announces the topic under study, summarizes what’s already known or been accomplished in previous research, and signals the rationale and goals are for the new research and the problem that the new research solves: How can researchers reprogram fibroblasts into iCPCs?] Here we report that a combination of 11 or 5 cardiac factors along with canonical Wnt and JAK/STAT signaling reprogrammed adult mouse cardiac, lung, and tail tip fibroblasts into iCPCs. The iCPCs were cardiac mesoderm-restricted progenitors that could be expanded extensively while maintaining multipo-tency to differentiate into cardiomyocytes, smooth muscle cells, and endothelial cells in vitro. Moreover, iCPCs injected into the cardiac crescent of mouse embryos differentiated into cardiomyocytes. iCPCs transplanted into the post-myocardial infarction mouse heart improved survival and differentiated into cardiomyocytes, smooth muscle cells, and endothelial cells. [Annotation for the previous four sentences: The methods the researchers developed to achieve their goal and a description of the results.] Lineage reprogramming of adult somatic cells into iCPCs provides a scalable cell source for drug discovery, disease modeling, and cardiac regenerative therapy.” (p. 354) [Annotation for the previous sentence: The significance or implications—for drug discovery, disease modeling, and therapy—of this reprogramming of adult somatic cells into iCPCs.]

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 is a thesis | A Complete Guide with Examples

Madalsa

Table of Contents

A thesis is a comprehensive academic paper based on your original research that presents new findings, arguments, and ideas of your study. It’s typically submitted at the end of your master’s degree or as a capstone of your bachelor’s degree.

However, writing a thesis can be laborious, especially for beginners. From the initial challenge of pinpointing a compelling research topic to organizing and presenting findings, the process is filled with potential pitfalls.

Therefore, to help you, this guide talks about what is a thesis. Additionally, it offers revelations and methodologies to transform it from an overwhelming task to a manageable and rewarding academic milestone.

What is a thesis?

A thesis is an in-depth research study that identifies a particular topic of inquiry and presents a clear argument or perspective about that topic using evidence and logic.

Writing a thesis showcases your ability of critical thinking, gathering evidence, and making a compelling argument. Integral to these competencies is thorough research, which not only fortifies your propositions but also confers credibility to your entire study.

Furthermore, there's another phenomenon you might often confuse with the thesis: the ' working thesis .' However, they aren't similar and shouldn't be used interchangeably.

A working thesis, often referred to as a preliminary or tentative thesis, is an initial version of your thesis statement. It serves as a draft or a starting point that guides your research in its early stages.

As you research more and gather more evidence, your initial thesis (aka working thesis) might change. It's like a starting point that can be adjusted as you learn more. It's normal for your main topic to change a few times before you finalize it.

While a thesis identifies and provides an overarching argument, the key to clearly communicating the central point of that argument lies in writing a strong thesis statement.

What is a thesis statement?

A strong thesis statement (aka thesis sentence) is a concise summary of the main argument or claim of the paper. It serves as a critical anchor in any academic work, succinctly encapsulating the primary argument or main idea of the entire paper.

Typically found within the introductory section, a strong thesis statement acts as a roadmap of your thesis, directing readers through your arguments and findings. By delineating the core focus of your investigation, it offers readers an immediate understanding of the context and the gravity of your study.

Furthermore, an effectively crafted thesis statement can set forth the boundaries of your research, helping readers anticipate the specific areas of inquiry you are addressing.

Different types of thesis statements

A good thesis statement is clear, specific, and arguable. Therefore, it is necessary for you to choose the right type of thesis statement for your academic papers.

Thesis statements can be classified based on their purpose and structure. Here are the primary types of thesis statements:

Argumentative (or Persuasive) thesis statement

Purpose : To convince the reader of a particular stance or point of view by presenting evidence and formulating a compelling argument.

Example : Reducing plastic use in daily life is essential for environmental health.

Analytical thesis statement

Purpose : To break down an idea or issue into its components and evaluate it.

Example : By examining the long-term effects, social implications, and economic impact of climate change, it becomes evident that immediate global action is necessary.

Expository (or Descriptive) thesis statement

Purpose : To explain a topic or subject to the reader.

Example : The Great Depression, spanning the 1930s, was a severe worldwide economic downturn triggered by a stock market crash, bank failures, and reduced consumer spending.

Cause and effect thesis statement

Purpose : To demonstrate a cause and its resulting effect.

Example : Overuse of smartphones can lead to impaired sleep patterns, reduced face-to-face social interactions, and increased levels of anxiety.

Compare and contrast thesis statement

Purpose : To highlight similarities and differences between two subjects.

Example : "While both novels '1984' and 'Brave New World' delve into dystopian futures, they differ in their portrayal of individual freedom, societal control, and the role of technology."

When you write a thesis statement , it's important to ensure clarity and precision, so the reader immediately understands the central focus of your work.

What is the difference between a thesis and a thesis statement?

While both terms are frequently used interchangeably, they have distinct meanings.

A thesis refers to the entire research document, encompassing all its chapters and sections. In contrast, a thesis statement is a brief assertion that encapsulates the central argument of the research.

Here’s an in-depth differentiation table of a thesis and a thesis statement.

Now, to craft a compelling thesis, it's crucial to adhere to a specific structure. Let’s break down these essential components that make up a thesis structure

15 components of a thesis structure

Navigating a thesis can be daunting. However, understanding its structure can make the process more manageable.

Here are the key components or different sections of a thesis structure:

Your thesis begins with the title page. It's not just a formality but the gateway to your research.

title-page-of-a-thesis

Here, you'll prominently display the necessary information about you (the author) and your institutional details.

  • Title of your thesis
  • Your full name
  • Your department
  • Your institution and degree program
  • Your submission date
  • Your Supervisor's name (in some cases)
  • Your Department or faculty (in some cases)
  • Your University's logo (in some cases)
  • Your Student ID (in some cases)

In a concise manner, you'll have to summarize the critical aspects of your research in typically no more than 200-300 words.

Abstract-section-of-a-thesis

This includes the problem statement, methodology, key findings, and conclusions. For many, the abstract will determine if they delve deeper into your work, so ensure it's clear and compelling.

Acknowledgments

Research is rarely a solitary endeavor. In the acknowledgments section, you have the chance to express gratitude to those who've supported your journey.

Acknowledgement-section-of-a-thesis

This might include advisors, peers, institutions, or even personal sources of inspiration and support. It's a personal touch, reflecting the humanity behind the academic rigor.

Table of contents

A roadmap for your readers, the table of contents lists the chapters, sections, and subsections of your thesis.

Table-of-contents-of-a-thesis

By providing page numbers, you allow readers to navigate your work easily, jumping to sections that pique their interest.

List of figures and tables

Research often involves data, and presenting this data visually can enhance understanding. This section provides an organized listing of all figures and tables in your thesis.

List-of-tables-and-figures-in-a-thesis

It's a visual index, ensuring that readers can quickly locate and reference your graphical data.

Introduction

Here's where you introduce your research topic, articulate the research question or objective, and outline the significance of your study.

Introduction-section-of-a-thesis

  • Present the research topic : Clearly articulate the central theme or subject of your research.
  • Background information : Ground your research topic, providing any necessary context or background information your readers might need to understand the significance of your study.
  • Define the scope : Clearly delineate the boundaries of your research, indicating what will and won't be covered.
  • Literature review : Introduce any relevant existing research on your topic, situating your work within the broader academic conversation and highlighting where your research fits in.
  • State the research Question(s) or objective(s) : Clearly articulate the primary questions or objectives your research aims to address.
  • Outline the study's structure : Give a brief overview of how the subsequent sections of your work will unfold, guiding your readers through the journey ahead.

The introduction should captivate your readers, making them eager to delve deeper into your research journey.

Literature review section

Your study correlates with existing research. Therefore, in the literature review section, you'll engage in a dialogue with existing knowledge, highlighting relevant studies, theories, and findings.

Literature-review-section-thesis

It's here that you identify gaps in the current knowledge, positioning your research as a bridge to new insights.

To streamline this process, consider leveraging AI tools. For example, the SciSpace literature review tool enables you to efficiently explore and delve into research papers, simplifying your literature review journey.

Methodology

In the research methodology section, you’ll detail the tools, techniques, and processes you employed to gather and analyze data. This section will inform the readers about how you approached your research questions and ensures the reproducibility of your study.

Methodology-section-thesis

Here's a breakdown of what it should encompass:

  • Research Design : Describe the overall structure and approach of your research. Are you conducting a qualitative study with in-depth interviews? Or is it a quantitative study using statistical analysis? Perhaps it's a mixed-methods approach?
  • Data Collection : Detail the methods you used to gather data. This could include surveys, experiments, observations, interviews, archival research, etc. Mention where you sourced your data, the duration of data collection, and any tools or instruments used.
  • Sampling : If applicable, explain how you selected participants or data sources for your study. Discuss the size of your sample and the rationale behind choosing it.
  • Data Analysis : Describe the techniques and tools you used to process and analyze the data. This could range from statistical tests in quantitative research to thematic analysis in qualitative research.
  • Validity and Reliability : Address the steps you took to ensure the validity and reliability of your findings to ensure that your results are both accurate and consistent.
  • Ethical Considerations : Highlight any ethical issues related to your research and the measures you took to address them, including — informed consent, confidentiality, and data storage and protection measures.

Moreover, different research questions necessitate different types of methodologies. For instance:

  • Experimental methodology : Often used in sciences, this involves a controlled experiment to discern causality.
  • Qualitative methodology : Employed when exploring patterns or phenomena without numerical data. Methods can include interviews, focus groups, or content analysis.
  • Quantitative methodology : Concerned with measurable data and often involves statistical analysis. Surveys and structured observations are common tools here.
  • Mixed methods : As the name implies, this combines both qualitative and quantitative methodologies.

The Methodology section isn’t just about detailing the methods but also justifying why they were chosen. The appropriateness of the methods in addressing your research question can significantly impact the credibility of your findings.

Results (or Findings)

This section presents the outcomes of your research. It's crucial to note that the nature of your results may vary; they could be quantitative, qualitative, or a mix of both.

Results-section-thesis

Quantitative results often present statistical data, showcasing measurable outcomes, and they benefit from tables, graphs, and figures to depict these data points.

Qualitative results , on the other hand, might delve into patterns, themes, or narratives derived from non-numerical data, such as interviews or observations.

Regardless of the nature of your results, clarity is essential. This section is purely about presenting the data without offering interpretations — that comes later in the discussion.

In the discussion section, the raw data transforms into valuable insights.

Start by revisiting your research question and contrast it with the findings. How do your results expand, constrict, or challenge current academic conversations?

Dive into the intricacies of the data, guiding the reader through its implications. Detail potential limitations transparently, signaling your awareness of the research's boundaries. This is where your academic voice should be resonant and confident.

Practical implications (Recommendation) section

Based on the insights derived from your research, this section provides actionable suggestions or proposed solutions.

Whether aimed at industry professionals or the general public, recommendations translate your academic findings into potential real-world actions. They help readers understand the practical implications of your work and how it can be applied to effect change or improvement in a given field.

When crafting recommendations, it's essential to ensure they're feasible and rooted in the evidence provided by your research. They shouldn't merely be aspirational but should offer a clear path forward, grounded in your findings.

The conclusion provides closure to your research narrative.

It's not merely a recap but a synthesis of your main findings and their broader implications. Reconnect with the research questions or hypotheses posited at the beginning, offering clear answers based on your findings.

Conclusion-section-thesis

Reflect on the broader contributions of your study, considering its impact on the academic community and potential real-world applications.

Lastly, the conclusion should leave your readers with a clear understanding of the value and impact of your study.

References (or Bibliography)

Every theory you've expounded upon, every data point you've cited, and every methodological precedent you've followed finds its acknowledgment here.

References-section-thesis

In references, it's crucial to ensure meticulous consistency in formatting, mirroring the specific guidelines of the chosen citation style .

Proper referencing helps to avoid plagiarism , gives credit to original ideas, and allows readers to explore topics of interest. Moreover, it situates your work within the continuum of academic knowledge.

To properly cite the sources used in the study, you can rely on online citation generator tools  to generate accurate citations!

Here’s more on how you can cite your sources.

Often, the depth of research produces a wealth of material that, while crucial, can make the core content of the thesis cumbersome. The appendix is where you mention extra information that supports your research but isn't central to the main text.

Appendices-section-thesis

Whether it's raw datasets, detailed procedural methodologies, extended case studies, or any other ancillary material, the appendices ensure that these elements are archived for reference without breaking the main narrative's flow.

For thorough researchers and readers keen on meticulous details, the appendices provide a treasure trove of insights.

Glossary (optional)

In academics, specialized terminologies, and jargon are inevitable. However, not every reader is versed in every term.

The glossary, while optional, is a critical tool for accessibility. It's a bridge ensuring that even readers from outside the discipline can access, understand, and appreciate your work.

Glossary-section-of-a-thesis

By defining complex terms and providing context, you're inviting a wider audience to engage with your research, enhancing its reach and impact.

Remember, while these components provide a structured framework, the essence of your thesis lies in the originality of your ideas, the rigor of your research, and the clarity of your presentation.

As you craft each section, keep your readers in mind, ensuring that your passion and dedication shine through every page.

Thesis examples

To further elucidate the concept of a thesis, here are illustrative examples from various fields:

Example 1 (History): Abolition, Africans, and Abstraction: the Influence of the ‘Noble Savage’ on British and French Antislavery Thought, 1787-1807 by Suchait Kahlon.
Example 2 (Climate Dynamics): Influence of external forcings on abrupt millennial-scale climate changes: a statistical modelling study by Takahito Mitsui · Michel Crucifix

Checklist for your thesis evaluation

Evaluating your thesis ensures that your research meets the standards of academia. Here's an elaborate checklist to guide you through this critical process.

Content and structure

  • Is the thesis statement clear, concise, and debatable?
  • Does the introduction provide sufficient background and context?
  • Is the literature review comprehensive, relevant, and well-organized?
  • Does the methodology section clearly describe and justify the research methods?
  • Are the results/findings presented clearly and logically?

  • Would the thesis be understandable and valuable to someone in your field?

Ensure to use this checklist to leave no ground for doubt or missed information in your thesis.

After writing your thesis, the next step is to discuss and defend your findings verbally in front of a knowledgeable panel. You’ve to be well prepared as your professors may grade your presentation abilities.

Preparing your thesis defense

A thesis defense, also known as "defending the thesis," is the culmination of a scholar's research journey. It's the final frontier, where you’ll present their findings and face scrutiny from a panel of experts.

Typically, the defense involves a public presentation where you’ll have to outline your study, followed by a question-and-answer session with a committee of experts. This committee assesses the validity, originality, and significance of the research.

The defense serves as a rite of passage for scholars. It's an opportunity to showcase expertise, address criticisms, and refine arguments. A successful defense not only validates the research but also establishes your authority as a researcher in your field.

Here’s how you can effectively prepare for your thesis defense .

Now, having touched upon the process of defending a thesis, it's worth noting that scholarly work can take various forms, depending on academic and regional practices.

One such form, often paralleled with the thesis, is the 'dissertation.' But what differentiates the two?

Dissertation vs. Thesis

Often used interchangeably in casual discourse, they refer to distinct research projects undertaken at different levels of higher education.

To the uninitiated, understanding their meaning might be elusive. So, let's demystify these terms and delve into their core differences.

Here's a table differentiating between the two.

Wrapping up

From understanding the foundational concept of a thesis to navigating its various components, differentiating it from a dissertation, and recognizing the importance of proper citation — this guide covers it all.

As scholars and readers, understanding these nuances not only aids in academic pursuits but also fosters a deeper appreciation for the relentless quest for knowledge that drives academia.

It’s important to remember that every thesis is a testament to curiosity, dedication, and the indomitable spirit of discovery.

Good luck with your thesis writing!

Frequently Asked Questions

A thesis typically ranges between 40-80 pages, but its length can vary based on the research topic, institution guidelines, and level of study.

A PhD thesis usually spans 200-300 pages, though this can vary based on the discipline, complexity of the research, and institutional requirements.

To identify a thesis topic, consider current trends in your field, gaps in existing literature, personal interests, and discussions with advisors or mentors. Additionally, reviewing related journals and conference proceedings can provide insights into potential areas of exploration.

The conceptual framework is often situated in the literature review or theoretical framework section of a thesis. It helps set the stage by providing the context, defining key concepts, and explaining the relationships between variables.

A thesis statement should be concise, clear, and specific. It should state the main argument or point of your research. Start by pinpointing the central question or issue your research addresses, then condense that into a single statement, ensuring it reflects the essence of your paper.

Executive summaries and abstracts both capture the essence of a project in a shorter form, but with differing levels of detail: an abstract is a highly condensed overview of the document, while an executive summary is a standalone version of the thesis in miniature.

See our handout on " What Goes in a Thesis Abstract? An Executive Summary? " for an overview of standard content and length—then, for more information and examples, read on!

For a more detailed explanation of abstracts, check out our infographics, tailored to your discipline:

  • Defense management
  • Social sciences

An abstract is a brief encapsulation of a document. Abstracts are quite limited in length (often about 200 words) and thus must be very concise, clear statements that convey a few key ideas:

  • The topic and significance of the research
  • The research question driving the inquiry
  • The methods used to answer the question
  • The findings and implications of the research

Understanding how an abstract is structured can also help you as a researcher. When conducting research , get in the habit of reading abstracts carefully to determine which documents closely fit your research needs.

Not all documents require an abstract, and most of your class papers won't. However, all NPS theses must have an abstract, and abstracts are often required for conference papers and articles submitted for publication .

Executive Summaries

Executive summaries are longer than abstracts, often running 2–5 pages. They summarize a larger document's purpose, methods, results, conclusions, and recommendations such that someone who reads  only the summary can glean a solid understanding of the research as a whole. Unlike abstracts, executive summaries can include citations and references .

Not all theses require an executive summary, so check with your advisor or department for guidance. The links below contain further information on the differences between abstracts and executive summaries.

In order to make your research easier to find by other researchers, it is a good idea to think about what searchable keywords are associated with your project. Make sure to include them in your abstract and executive summary!

Abstract vs Introduction – Differences Explained

Dr Harry Hothi

  • By Dr Harry Hothi
  • August 29, 2020

Abstract vs Introduction

Any academic write up of a research study or project will require the inclusion of an abstract and introduction. If you pick up any example of a research paper for a journal, dissertation for a Masters degree or a PhD thesis, you’ll see the abstract, followed by the introduction. At first glance you’ll notice that the abstract is much shorter in length, typically a quarter or third of a page of A4. The introduction on the other hand is longer, taking up at least an entire page of writing.

Beyond the length, what are the differences in the content of the two sections? In short, the abstract is a summary of the entire study, describing the context, research aim, methods, results and key conclusions. The introduction gives more detail on the background of the subject area, the motivation for the study and states the aims and objectives.

Read on to learn more.

What is an Abstract?

The main purpose of an abstract is to succinctly give the reader an overview of why the study was needed, what the purpose of the project was, the research question, the key materials and methods that were used, the main results and what conclusions were drawn from this. Many abstracts also conclude with a sentence on the significance or impact of the research. These are sometimes also referred to as an executive summary.

The reader should have an understanding of the paper topic and what the study was about from the abstract alone. He or she can then decide if they want to read the paper or thesis in more detail.

Abstracts are particularly useful for researchers performing a literature review, which involves critically evaluating a large number of papers. Reading the abstract enables them to quickly ascertain the key points of a paper, helping them identify which ones to read in full.

Abstracts are also very important for learning more about the work performed in papers that are hidden behind academic journal paywalls (i.e. those that are not open access). Abstracts are always made freely available, allowing a researcher to understand the context and main point of the work and then decide if it’s worth paying to read the entire paper. These are sometimes referred to as the ‘de facto introduction’ to the research work as it’s usually the first section people read about your study, after the title page.

How do you Write an Abstract?

The majority of academic journals place a limit of 250 words on the length of the abstract in papers submitted to them. They do this to ensure you give a quick overview of only the most important information from your study, helping the reader decide if they want to read the whole paper too. Make sure you double check the specific requirements of your target journal before you start writing.

Universities or other academic institutions often allow up to 500 words for an abstract written for a doctoral thesis.

Abstracts can be either structured or unstructured in the way they are formatted. A structured abstract contains separate headings to guide the reader through the study. Virtually all STEM journals will require this format be used for a researcharticle. The exact names used for each heading can differ but generally there are defined as:

  • Background. This is also sometimes called the Introduction. This section should give an overview of what is currently known about the research topic and what the gap in knowledge is. The reader should understand the problem your research will address; i.e. what was your study needed. Don’t include any references or citations in the abstract.
  • Aim and Objective. Give a brief explanation of what the study intended to achieve and state the research question or questions that you proposed. Some authors also include the hypothesis here too.
  • Materials and Methods. Use the methods section to describe what you investigated, what the study design was and how you carried it out.
  • Results. Give an overview of your key findings.
  • Discussion and Conclusion. Some journals may ask for these two terms to be used as separated headings. These sections explain why you may have obtained the results that you did, what this means and what the significance or impact of this might be.

An informative abstract should provide a concise summary of all the important points in your research project, including what the central question relating to the subject matter was. Make it interesting to read too; this may be the difference between your abstract being accepted or rejected if you decide to submit it to an upcoming conference. Reviewers for large conferences often have to read hundreds of abstracts so make sure yours stands out by being easy to read and follow.

It’s less common that you’ll be asked to write an unstructured abstract. If you are, however, be aware that the key difference is that an unstructured abstract does not include separate headings. The flow of the abstract text should still follow the 5 points listed above but they should all be written within one long paragraph.

What is the Introduction?

The introduction section is the first main written work presented after the abstract in your paper manuscript or thesis. In a research paper, the introduction will be followed by a section on the materials and methods. In thesis writing, the introduction will be followed by the literature review .

The main aim of introduction writing is to give the reader more detail on the background information of the study. It should include a brief description of the key current knowledge that exists based on the work presented in previous literature and where the gaps in knowledge are. The introduction should convey why your research was needed in order to add new understanding to your subject area. Make sure that you reference all the publications that you refer to.

When writing an introduction for a scientific paper you should also include the aim of your study and the research objectives/questions. If relevant, also include your hypothesis or (null hypothesis).

How do you Structure the Introduction?

The general rule of thumb for a research paper is to use size 12 Times New Roman font, double spaced. Write four separate paragraphs which together are no longer than one page in length. Structure the four paragraphs as follows:

  • Set the context of the research study, giving background information about the subject area.
  • Describe what is currently know from previously published work and what is poorly understood – i.e. the research gap.
  • Explain how addressing this gap in knowledge is important for your research field – i.e. why this study is needed.
  • Give a broad overview of the aims, objectives and hypothesis of the study.

You should not describe the research method used in this section nor any results and conclusions.

You should be clear now on what the differences between an abstract vs introduction are. The best way to improve your academic writing skills for these are to read other examples from other  research articles and start writing!

Abstract vs. Introduction—What’s the Difference?

Abstract vs. Introduction—What’s the Difference?

3-minute read

  • 21st February 2022

If you’re a student who’s new to research papers or you’re preparing to write your dissertation , you might be wondering what the difference is between an abstract and an introduction.

Both serve important purposes in a research paper or journal article , but they shouldn’t be confused with each other. We’ve put together this guide to help you tell them apart.

What’s an Introduction?

In an academic context, an introduction is the first section of an essay or research paper. It should provide detailed background information about the study and its significance, as well as the researcher’s hypotheses and aims.

But the introduction shouldn’t discuss the study’s methods or results. There are separate sections for this later in the paper.

An introduction must correctly cite all sources used and should be about four paragraphs long, although the exact length depends on the topic and the style guide used.

What’s an Abstract?

While the introduction is the first section of a research paper, the abstract is a short summary of the entire paper. It should contain enough basic information to allow you to understand the content of the study without having to read the entire paper.

The abstract is especially important if the paper isn’t open access because it allows researchers to sift through many different studies before deciding which one to pay for.

Since the abstract contains only the essentials, it’s usually much shorter than an introduction and normally has a maximum word count of 200–300 words. It also doesn’t contain citations.

The exact layout of an abstract depends on whether it’s structured or unstructured. Unstructured abstracts are usually used in non-scientific disciplines, such as the arts and humanities, and usually consist of a single paragraph.

Structured abstracts, meanwhile, are the most common form of abstract used in scientific papers. They’re divided into different sections, each with its own heading. We’ll take a closer look at structured abstracts below.

Structuring an Abstract

A structured abstract contains concise information in a clear format with the following headings:

●  Background: Here you’ll find some relevant information about the topic being studied, such as why the study was necessary.

●  Objectives: This section is about the goals the researcher has for the study.

●  Methods: Here you’ll find a summary of how the study was conducted.

●  Results: Under this heading, the results of the study are presented.

●  Conclusions: The abstract ends with the researcher’s conclusions and how the study can inform future research.

Each of these sections, however, should contain less detail than the introduction or other sections of the main paper.

Differentiating between the abstract and the introduction of a research paper

  • 3 minute read
  • 45.6K views

Table of Contents

While writing a manuscript for the first time, you might find yourself confused about the differences between an abstract and the introduction. Both are adjacent sections of a research paper and share certain elements. However, they serve entirely different purposes. So, how does one ensure that these sections are written correctly?

Knowing the intended purpose of the abstract and the introduction is a good start!

What is an abstract?

An abstract is a very short summary of all the sections of your research paper—the introduction, objectives, materials and methods, results, and conclusion. It ends by emphasising the novelty or relevance of your study, or by posing questions for future research. The abstract should cover all important aspects of the study, so that the reader can quickly decide if the paper is of their interest or not.

In simple terms, just like a restaurant’s menu that provides an overview of all available dishes, an abstract gives the reader an idea of what the research paper has to offer. Most journals have a strict word limit for abstracts, which is usually 10% of the research paper.

What is the purpose of an abstract?

The abstract should ideally induce curiosity in the reader’s mind and contain strategic keywords. By generating curiosity and interest, an abstract can push readers to read the entire paper or buy it if it is behind a paywall. By using keywords strategically in the abstract, authors can improve the chances of their paper appearing in online searches.

What is an introduction?

The introduction is the first section in a research paper after the abstract, which describes in detail the background information that is necessary for the reader to understand the topic and aim of the study.

What is the purpose of an introduction?

The introduction points to specific gaps in knowledge and explains how the study addresses these gaps. It lists previous studies in a chronological order, complete with citations, to explain why the study was warranted.

A good introduction sets the context for your study and clearly distinguishes between the knowns and the unknowns in a research topic.

Often, the introduction mentions the materials and methods used in a study and outlines the hypotheses tested. Both the abstract and the introduction have this in common. So, what are the key differences between the two sections?

Key differences between an abstract and the introduction:

  • The word limit for an abstract is usually 250 words or less. In contrast, the typical word limit for an introduction is 500 words or more.
  • When writing the abstract, it is essential to use keywords to make the paper more visible to search engines. This is not a significant concern when writing the introduction.
  • The abstract features a summary of the results and conclusions of your study, while the introduction does not. The abstract, unlike the introduction, may also suggest future directions for research.
  • While a short review of previous research features in both the abstract and the introduction, it is more elaborate in the latter.
  • All references to previous research in the introduction come with citations. The abstract does not mention specific studies, although it may briefly outline previous research.
  • The abstract always comes before the introduction in a research paper.
  • Every paper does not need an abstract. However, an introduction is an essential component of all research papers.

Abstract Vs Introduction: Key Similarities and Differences

Abstract vs Introduction

Is an abstract the same as an introduction? This is one of the questions we receive most frequently, so we thought it would be a good idea to write an article about the abstract vs introduction problem. Most students don’t know how to differentiate between the two, especially if they are new to academic writing. Even though the two things are somewhat similar, there is at least one major difference between introduction and abstract. In this article, we will discuss the similarities and differences between the two. What is the difference between an abstract and an introduction? Let’s find out!

The Abstract Vs Introduction Problem

Introduction vs abstract: which one does what? Because many professors don’t explain these two terms to their students, it’s easy to confuse them. We consider that this is not the students’ fault. If they don’t know the difference between an abstract and an introduction, it’s easy to make a grave mistake. Of course, you will get penalized harshly for this. This blog post aims to provide information about abstract vs introduction scientific paper writers need to make sure they don’t get an F on their next essay.

Abstract and Introduction: What Are They?

So, let’s discuss abstract vs introduction APA style. An abstract is basically a summary of a complex paper (such as a thesis or a research paper).

The abstract summarizes all the different parts of the paper, including the research problem, the objectives, the methods, the results, and the conclusion. After reading the abstract, the reader should know exactly what the paper is about and how it is structured. The length of an abstract is around 250-300 words. The introduction, on the other hand, is there to give your readers an idea of what you are about to talk about and introduce your thesis statement.

It can contain a bit of background information, but it does not delve into the specifics of your research methods or results. Also, the introduction does not discuss the conclusion of the paper in any way.

The Key Difference Between Abstract and Introduction

OK, but what is the major difference between abstract and introduction? In simple terms, the abstract is a summary of the entire research paper. It briefly discusses the methods, results and conclusion. The introduction, on the other hand, is there to entice the reader to read the entire paper. It discusses just the background of the problem and the objectives of the paper. You will never see the conclusion being discussed in an introduction.

Is an APA abstract vs introduction different from MLA or other types of academic writing? No, the abstract and the introduction are just as different regardless of the academic writing style. You should never confuse one for the other because the consequences can be a rejected paper or at the very least a very low grade.

Introduction vs Abstract: The Similarities

Now that you know the main difference between an abstract and introduction, it’s time to talk about similarities. This should help you avoid any confusion:

  • Both the introduction and the abstract are placed at the beginning of a research paper. In fact, an abstract can be considered a de-facto introduction.
  • Both the abstract and the introduction are there to provide some information about the subject and about the objectives of your research paper.
  • Both can be used as a way to attract the interest of a reader.

However, this is where the similarities end. Never assume that you can write an introduction in place of an abstract. Of course, you can’t write an abstract in place of an introduction either. This is the information about abstract vs introduction lab report writers need to know before they start writing their first paper. We know that sometimes writing an abstract can be more difficult than the introduction to abstract algebra in high school. However, with practice, you will quickly get the hang of it.

Abstract and Introduction Examples

To help you understand the meaning and role of an abstract better, we have written an example abstract for you and broken it down into pieces:

As of 2023, residual herbicide that is accumulating in certain crops is posing a growing threat to the rice-wheat rotation in northern India. (The background part) When it comes to pesticides and pesticide metabolites, green manure has been shown to stimulate ample co-mineralization. By incorporating it into the soil, the effects of the herbicide residue can be mitigated. (The objectives part) During a three-year study at the North Indian Wheat Research Institute, Azolla Pinata and A. Carolingiana have been used as green manure. The effects of the green manure on the Propanil and Buthachlor herbicides has been evaluated, as well as the mineralization and co-metabolization of the herbicides, using a process known as liquid chromatography. (The material and methods part) Initial results indicate that Azolla Pinata caused the Propanil herbicide to co-mineralize in 14 days. However, the green manure did not have the intended effect on the Buthachlor herbicide during the study. (The findings part) After analyzing the findings of the study, we can say for certain that Azolla Pinata used as green manure can prevent residual Propanil accumulation. (The conclusion part)

An example introduction for the paper would look something like this:

Residual herbicides are posing a growing threat to the systems of rice-wheat rotation in Northern India. According to a recent study by the North Indian Wheat Research Institute, Azolla Pinata is able to co-mineralize some herbicides. Understanding the process by which this happens is important for the future of Indian rice and wheat crops. This research paper aims to answer the following question: how does green manure co-mineralize certain herbicides? We will first analyze the soil and the herbicide accumulation, then we will discuss the effects of green manure, and finally we will analyze the potential applications.

Difference Between Writing An Abstract And A Synopsis

  • Difference Between Writing An Abstract

By AnkitJain Category : PhD Synopsis

This is not something for us to tell, everyone already knows that a doctoral degree and a successful PhD research serve as the highest academic qualifications in a subject area. This means it has to be as perfect as it can be.

This is why it is important to understand the basics of developing a PhD thesis which brings us to one of the most important factors of a thesis; that is, writing the abstract and thesis synopsis.

A lot of PhD aspirants often struggle with the difference in writing an abstract and a synopsis. Here, we have enlisted a few points which will help you in understanding the difference between writing an abstract and synopsis for PhD Thesis .

What Is An Abstract?

Sticking to the point, an abstract is simply a short (ranging from 200-300 words) overview of the PhD thesis which is developed for the readers, audience, future researchers, and sometimes even for your future job applications, where the reader does not have much time to go through your entire thesis to understand what the research is about.

The abstract must only contain the highlights of the PhD thesis, like:

  • the research introduction
  • the research purpose
  • the problem statement
  • the research methodology and framework
  • the research findings
  • the result and conclusion

Now, you see, to include all these points in a 200-300 words short paragraph or roughly one page worth of content, the abstract only has 2-3 lines dedicated to each section. It helps the readers and audience to evaluate whether the PhD thesis focuses on the things they are looking into or not.

What Is A Thesis Synopsis?

A PhD thesis synopsis is also a summarized version of the complete thesis research but it is much longer and detailed than the abstract of the thesis. In fact, in some cases, the thesis synopsis might also include the abstract of the thesis, if the university guidelines mention it.

A synopsis writing strictly include the following areas:

  • the research title and topic introduction
  • the research requirements
  • the literature review
  • the research gap and problem statement
  • the research methodology 
  • the research significance, scope and objectives
  • the expected budget and deadline of the research

A PhD thesis synopsis is also known as proposal because it proposes the idea of the researcher to the research committee. It is important to understand that synopsis, thus, needs to be well-curated in order to get the acceptance for conducting the whole research.

Difference Between Thesis Abstract And Synopsis

To keep it easily interpretable and straightforward, we have divided the differences in points on the basis of which you can deduct the basic differences between the two.

An abstract is written after the PhD thesis has been developed as it includes the result section as well and it needs to be added with the thesis while submitting it to the research committee or sending it to get published.

Whereas, a thesis synopsis needs to be written before the thesis development and must receive the acceptance by the concerned authorities in order to get the approval for the research conduct.

Significance:

The abstract is mostly significant in boosting the career and is more prominent for the later stages that come after the doctoral degree. As in getting a job or publishing the research where the editors and viewers go through the abstract first because of the time shortage.

As for the synopsis, it is more important for academia and shows the ideas and perceptions of the young scholars.

The abstract is usually written in one of two paragraphs and appears first in the PhD thesis; whereas, the synopsis contains different headlines just like the different chapters in PhD thesis writing to clearly discuss all those areas and is not connected with the PhD thesis but is submitted separately.

Inclusions:

Other than the brief introduction and highlights of the PhD thesis, the abstract also talks about the result. The main focus remains on giving the complete overview of the research. However, the synopsis writing does not include the results and conclusions. It mainly focuses on the importance of the research and the course of development providing a framework to the research that needs to be conducted.

A smart person once said “if you want a thing done well, then do it yourself”, but we say when you can get the better work, then don’t settle for anything less that can affect your PhD research and academic career in one blow.

A lot of scholars make mistakes when they end up writing the summary of synopsis in the abstract considering it right. Having errors in complex areas can still be avoided considering the overall research, but having errors in the basics may portray you as ignorant in regards to your study.

The difference between an abstract and an introduction.

Introductions and abstracts are two things that seem very similar, but are actually quite different. However, once you know the difference, they are easy to keep separate from each other.

An abstract is, at its most basic level, a summary. It outlines all of the important parts of your paper to the reader, so they can figure out if your paper is worth reading. This is why abstracts are important in the scientific field. They are a fast way for someone to analyze what is going to be said, and if that information is going to be beneficial for them.

An introduction provides the reader with detailed background information about a topic. This helps the reader make sense of what is going to be said later in the paper. If they do not understand the most basic parts of your topic, then they are not going to understand what you are trying to convey.

Now that you know the difference between the two, here is some advice for writing them:

The abstract is easiest to write last. By that point, you will have already written everything else, and you should know the important takeaways of your work. In the abstract, you should introduce your topic, discuss why you choose this topic, state your hypothesis, and reveal the results of your study. Remember, the abstract is like a summary. You should not go into a lot of detail here. Provide the reader with enough information that they can digest what you are saying. You will explain everything else in detail later in your paper. 

The introduction is one of the most important parts of your paper. However, introductions vary based on the genre of paper. For this blog post, introductions for scientific papers are going to be discussed because abstracts are a staple of scientific reports. An introduction for a scientific paper should explain the reasoning behind why you choose this experiment, provide background information about the topic, reference other studies done on similar topics, and state your hypothesis. You want to make sure your reader can understand what is going to be said later in the paper. 

Here are a few websites that have some more information about the two:

Abstract Vs. Introduction — Do you know the difference?

' src=

Ross wants to publish his research. Feeling positive about his research outcomes, he begins to draft his manuscript. After completing the abstract, he proceeds to write the introduction. That’s when he pauses in confusion. Do the abstract and introduction mean the same? How is the content for both the sections different?

This is a dilemma faced by several young researchers while drafting their first manuscript. An  abstract  is similar to a summary except that it is more concise and direct. Whereas, the  introduction  section of your paper is more detailed. It states why you conducted your study, what you wanted to accomplish, and what is your hypothesis.

This blog will allow us to learn more about the difference between the abstract and the introduction.

What Is an Abstract for a Research Paper?

An abstract provides the reader with a clear description of your research study and its results without the reader having to read the entire paper. The details of a study, such as precise methods and measurements, are not necessarily mentioned in the abstract. The abstract is an important tool for researchers who must sift through hundreds of papers from their field of study.

The abstract  holds more significance  in articles without open access. Reading the abstract would give an idea of the articles, which would otherwise require monetary payment for access. In most cases, reviewers will read the abstract to decide whether to continue to review the paper, which is important for you.

Your abstract should begin with a background or objective to clearly state why the research was done, its importance to the field of study, and any previous roadblocks encountered. It should include a very concise version of your methods, results, and conclusions but no references. It must be brief while still providing enough information so that the reader need not read the full article. Most journals ask that the abstract be no more than 200–250 words long.

Format of an Abstract

There are two general   formats — structured and unstructured. A  structured abstract   helps the reader find pertinent information  very quickly. It is divided into sections clearly defined by headings as follows:

  • Background : Latest information on the topic; key phrases that pique interest (e.g., “…the role of this enzyme has never been clearly understood”).
  • Objective : The research goals; what the study examined and why.
  • Methods : Brief description of the study (e.g., retrospective study).
  • Results : Findings and observations.
  • Conclusions : Were these results expected? Whether more research is needed or not?

Authors get tempted to write too much  in an abstract but it is helpful to remember that there is usually a maximum word count. The main point is to relay the important aspects of the study without sharing too many details so that the readers do not have to go through the entire manuscript text for finding more information.

The  unstructured abstract  is often used in fields of study that do not fall under the category of science. This type of abstracts does not have different sections. It summarizes the manuscript’s objectives, methods, etc., in one paragraph.

Lastly, you must check the author guidelines of the target journal. It will describe the format required and the maximum word count of your abstract.

What Is an Introduction?

Your introduction is the first section of your research paper . It is not a repetition of the abstract. It does not provide data about methods, results, or conclusions. However, it  provides more in-depth information  on the background of the subject matter. It also explains your hypothesis , what you attempted to discover, or issues that you wanted to resolve. The introduction will also explain if and why your study is new in the subject field and why it is important.

It is often a good idea to wait until the rest of the paper is completed before drafting your introduction. This will help you to stay focused on the manuscript’s important points. The introduction, unlike the abstract, should contain citations to references. The information will help guide your readers through the rest of your document. The key tips for writing an effective introduction :

  • Beginning:  The importance of the study.
  • Tone/Tense:  Formal, impersonal; present tense.
  • Content:  Brief description of manuscript but without results and conclusions.
  • Length:  Generally up to four paragraphs. May vary slightly with journal guidelines.

Abstract

Once you are sure that possible doubts on the difference between the abstract and introduction are clear, review and submit your manuscript.
