What's Your Question?

Understanding APA Format

If you’re writing academically, chances are you’ve been tasked with writing a paper that follows APA style. Although there’s a learning curve involved with adhering to APA style, it’s possible to learn the basics so you can turn in your assignments.

What Is APA Style?

APA is the official academic style of the American Psychological Association. This style was created in 1929 when a group of professionals worked together to devise a set of style rules for scientific writing as a means of making these documents easier to read and understand.

If an assignment indicates APA style, you will need to adhere to these style rules. These guidelines ensure that your document is consistent and uniform with elements such as punctuation, headings and subheadings, abbreviations, numbers, tables and figures and citations.

Main Sections of a Document

APA style dictates the format of the main sections of a document.

The title page includes a running head, the author’s name and the school.

The abstract is a succinct summary of the document. APA style dictates that abstracts be no more than 250 words, although some instructors give leeway regarding the length.

The main body of the document is the text of the essay or report. Some reports are divided into separate sections.

Your reference section follows the body. It includes a list of references you cited in your document.

How to Reference APA Style

In-text citations appear within the text, identifying any information you cite. APA format for in-text citations includes the author’s name and the date of the publication.

The reference page always begins on a new page with the title “References” centered at the top. Include all entries in alphabetical order, and each entry’s first line begins at the left margin, and additional lines are indented. Place titles of newspapers, magazines, journals and books in italics, and double-space the reference section.

Double-check that all of your sources appear as both in-text citations and in the reference section.

Use an APA Sample Paper

An APA style example can be helpful if you’re learning this style and trying to apply it to a writing assignment. Many schools and universities maintain resource web pages with APA samples to show students how to follow this style.

More APA Tips

If you’re struggling with creating APA citations and references, use a citation machine to check your work. You simply fill in the citation and click a button, and the tool tells you if you made any errors.

Consider hiring an academic editor to check your work after you finish writing. The editor can find and correct errors to make sure your document adheres to APA.

How to Write an APA Research Paper

Psychology/neuroscience 201, v iew in pdf format.

An APA-style paper includes the following sections: title page, abstract, introduction, method, results, discussion, and references. Your paper may also include one or more tables and/or figures. Different types of information about your study are addressed in each of the sections, as described below.

General formatting rules are as follows:

Do not put page breaks in between the introduction, method, results, and discussion sections.

The title page, abstract, references, table(s), and figure(s) should be on their own pages. The entire paper should be written in the past tense, in a 12-point font, double-spaced, and with one-inch margins all around.

(see sample on p. 41 of APA manual)

Abstract (labeled, centered, not bold)

No more than 120 words, one paragraph, block format (i.e., don’t indent), double-spaced.

Introduction

(Do not label as “Introduction.” Title of paper goes at the top of the page—not bold)

The introduction of an APA-style paper is the most difficult to write. A good introduction will summarize, integrate, and critically evaluate the empirical knowledge in the relevant area(s) in a way that sets the stage for your study and why you conducted it. The introduction starts out broad (but not too broad!) and gets more focused toward the end. Here are some guidelines for constructing a good introduction:

Method (labeled, centered, bold)

The Method section of an APA-style paper is the most straightforward to write, but requires precision. Your goal is to describe the details of your study in such a way that another researcher could duplicate your methods exactly.

The Method section typically includes Participants, Materials and/or Apparatus, and Procedure sections. If the design is particularly complicated (multiple IVs in a factorial experiment, for example), you might also include a separate Design subsection or have a “Design and Procedure” section.

Note that in some studies (e.g., questionnaire studies in which there are many measures to describe but the procedure is brief), it may be more useful to present the Procedure section prior to the Materials section rather than after it.

Participants (labeled, flush left, bold)

Total number of participants (# women, # men), age range, mean and SD for age, racial/ethnic composition (if applicable), population type (e.g., college students). Remember to write numbers out when they begin a sentence.

Materials (labeled, flush left, bold)

Carefully describe any stimuli, questionnaires, and so forth. It is unnecessary to mention things such as the paper and pencil used to record the responses, the data recording sheet, the computer that ran the data analysis, the color of the computer, and so forth.

Apparatus (labeled, flush left, bold)

Include an apparatus section if you used specialized equipment for your study (e.g., the eye tracking machine) and need to describe it in detail.

Procedure (labeled, flush left, bold)

What did participants do, and in what order? When you list a control variable (e.g., “Participants all sat two feet from the experimenter.”), explain WHY you did what you did.  In other words, what nuisance variable were you controlling for? Your procedure should be as brief and concise as possible. Read through it. Did you repeat yourself anywhere? If so, how can you rearrange things to avoid redundancy? You may either write the instructions to the participants verbatim or paraphrase, whichever you deem more appropriate. Don’t forget to include brief statements about informed consent and debriefing.

Results (labeled, centered, bold)

In this section, describe how you analyzed the data and what you found. If your data analyses were complex, feel free to break this section down into labeled subsections, perhaps one section for each hypothesis.

Discussion (labeled, centered, bold)

The goal of the discussion section is to interpret your findings and place them in the broader context of the literature in the area. A discussion section is like the reverse of the introduction, in that you begin with the specifics and work toward the more general (funnel out). Some points to consider:

Final paragraph: Be sure to sum up your paper with a final concluding statement. Don’t just trail off with an idea for a future study. End on a positive note by reminding your reader why your study was important and what it added to the literature.

References (labeled, centered, not bold)

Provide an alphabetical listing of the references (alphabetize by last name of first author). Double-space all, with no extra spaces between references. The second line of each reference should be indented (this is called a hanging indent and is easily accomplished using the ruler in Microsoft Word). See the APA manual for how to format references correctly.

Examples of references to journal articles start on p. 198 of the manual, and examples of references to books and book chapters start on pp. 202. Digital object identifiers (DOIs) are now included for electronic sources (see pp. 187-192 of APA manual to learn more).

Journal article example: [Note that only the first letter of the first word of the article title is capitalized; the journal name and volume are italicized. If the journal name had multiple words, each of the major words would be capitalized.] 

Ebner-Priemer, U. W., & Trull, T. J. (2009). Ecological momentary assessment of mood disorders and mood dysregulation. Psychological Assessment, 21, 463-475. doi:10.1037/a0017075

Book chapter example: [Note that only the first letter of the first word of both the chapter title and book title are capitalized.]

Stephan, W. G. (1985). Intergroup relations. In G. Lindzey & E. Aronson (Eds.), The handbook of social psychology (3 rd ed., Vol. 2, pp. 599-658). New York: Random House.

Book example: Gray, P. (2010). Psychology (6 th ed.). New York: Worth

Table There are various formats for tables, depending upon the information you wish to include. See the APA manual. Be sure to provide a table number and table title (the latter is italicized). Tables can be single or double-spaced.

Figure If you have more than one figure, each one gets its own page. Use a sans serif font, such as Helvetica, for any text within your figure. Be sure to label your x- and y-axes clearly, and make sure you’ve noted the units of measurement of the DV. Underneath the figure provide a label and brief caption (e.g., “Figure 1. Mean evaluation of job applicant qualifications as a function of applicant attractiveness level”). The figure caption typically includes the IVs/predictor variables and the DV. Include error bars in your bar graphs, and note what the bars represent in the figure caption: Error bars represent one standard error above and below the mean.

In-Text Citations: (see pp. 174-179 of APA manual) When citing sources in your paper, you need to include the authors’ names and publication date.

You should use the following formats:

Secondary Sources

“Secondary source” is the term used to describe material that is cited in another source. If in his article entitled “Behavioral Study of Obedience” (1963), Stanley Milgram makes reference to the ideas of Snow (presented above), Snow (1961) is the primary source, and Milgram (1963) is the secondary source.

Try to avoid using secondary sources in your papers; in other words, try to find the primary source and read it before citing it in your own work. If you must use a secondary source, however, you should cite it in the following way:

Snow (as cited in Milgram, 1963) argued that, historically, the cause of most criminal acts... The reference for the Milgram article (but not the Snow reference) should then appear in the reference list at the end of your paper.

How to Write a Research Paper in APA Format — A Complete Guide

' src=

Completed your research experiments and collated your results? Does it feel like you have crossed a major hurdle in your research journey? No, not even close! What lies next is — publishing your research work for it to reach the science world! The process of publishing a research paper is so intricate, if you miss one aspect, you could end up struggling with revisions and reworks or getting a rejection! Thus, there is a necessity of following an exceptional mode of writing. The APA style research format comes to a researcher’s rescue.

This article discusses how to effortlessly write an APA style research paper and how it is necessary to understand the basic elements of APA style research paper in order to write an article in APA style research format.

Table of Contents

What Is APA Style?

The APA format is the official style of American Psychological Association (APA) and is commonly used to cite sources in psychology, education and social sciences. APA research paper format is widely used in the research publishing industry.

Students and researchers usually get confused with various research paper writing formats and are unclear about the requirements from the research publication journals. Therefore, the best way to deal with beginning to write a research paper is to first know the journal’s requirement and then follow the guidelines accordingly.

Though the reference section may change over the course of time, the information related to the other sections in APA research paper format is similar and could be referred to, for writing an exemplary research paper.

Guidelines for APA Style Paper (7th edition)

An APA style research format is different as compared to a term paper, a creative writing paper, a composition-style paper, or a thought paper. Throughout the paper you need to apply these guidelines while writing the paper –

Page Layout:

Type the content and keep double-space on standard-sized paper (8.5” x 11”), with 1” margins on all sides.

You should indent the first line of every paragraph 0.5 inches

Include a page number on every page.

You could use an accessible font like Times New Roman 12pt., Arial 11pt., or Georgia 11pt.

APA Research Paper Sections

The APA research paper format is based on seven main components: title page, abstract, introduction, methods, results, discussion, and references. The sections in APA-style paper are as follows:

1. Title Page

As per the APA research paper format, the title should be between 10-12 words and should reflect the essence of the paper. After writing the title, write your name followed by name of the college. Furthermore, create a page header using the “View Header” function in MS Word and on the title page include a running head — a short title that appears at the top of pages of published articles (flush left) and page number on the same line (flush right). The running head should not exceed 50 characters, including punctuation and spacing. Moreover, you could use the toolbox to insert a page number, so that it automatically numbers each page.

APA research paper format

2. Abstract

Abstract should contain no more than 120 words , and should be one paragraph written in block format with double spacing. Additionally, state the topic in a sentence or two. Also, provide overview of methods, results, and discussion.

3. Introduction

An introduction of APA research paper format is the most difficult section to write. A good introduction critically evaluates the empirical knowledge in the relevant area(s) in a way that defines the knowledge gap and expresses your aim for your study and why you conducted it. However, the challenge here is to keep the reader’s interest in reading your paper.

A good introduction keeps readers engaged with your paper. For writing an interesting introduction, researchers should introduce logical flow of ideas which will eventually lead to the research hypothesis . Furthermore, while incorporating references into your introduction, do not describe every single study in complete detail. Summarize the key findings from the article and do not quote from the articles, instead paraphrase the content .

The method section in APA research paper format is straightforward. However, the protocol and requirements should be mentioned precisely. The goal of this section is to describe your study and experiments in detail, so that there is no issue in reproducibility of results and other researchers could duplicate your methods effectively.

This section includes Materials and/or Apparatus and Experiments/Procedures/Protocols. Furthermore, keep the procedures brief and accurate, and make sure to read through so as to not repeat the steps or avoid redundancy.

In this section, you could describe how you analyzed the data and explain your findings. If your data analyses are complex, then break the section into subsections, ideally a subsection for each hypothesis and elaborate the subsections by using statistical analysis and including tables or figures to represent results visually. Most importantly, do not share interpretation of the results here. You can interpret and explain the results in the discussion section.

6. Discussion

Results are interpreted and understood in this section. Discussion section helps understand the research hypothesis better and places the results in the broader context of the literature in the area. This section is the reversal of introduction section, wherein you begin with the specifics and explain the general understanding of the topics.

In discussion, you start with a brief of your main findings, followed by explaining if your research findings support your hypothesis. Furthermore, you could explain how your findings enhance or support the existing literature on the topic. Connect your results with some of the literature mentioned in the introduction to bring your story back to full circle. You could also mention if there are any interesting or surprising findings in your results. Discuss other theories which could help you justify your surprising results.

Explain the limitation of your study and mention all the additional questions that were generated from your study. You could also mention what further research should be conducted on the topic and what are the knowledge gaps in the current body of research. Finally, mention how your results could relate to the larger issues of human existence and highlight “the big picture” for your readers.

7. References

Provide an alphabetical listing of the references. Do not keep extra spaces between references and double-space all the references. The second line of each reference should be intended. You could refer to the examples (mentioned below) to know how to format references correctly.

I. Journal Article:

Only first letter of the first word of the article title is capitalized; the journal name and volume are italicized. If the journal name had multiple words, each of the major words are capitalized.

Example: Ebner-Priemer, U. W., & Trull, T. J. (2009). Ecological momentary assessment of mood disorders and mood dysregulation. Psychological Assessment, 21 , 463-475. doi:10.1037/a0017075

II. Book Chapter:

Only the first letter of the first word of both the chapter title and book title are capitalized.

Example: Stephan, W. G. (1985). Intergroup relations. In G. Lindzey & E. Aronson (Eds.), The handbook of social psychology (3rd ed., Vol. 2, pp. 599-658). New York: Random House.

Example: Gray, P. (2010). Psychology (6th ed.). New York: Worth

There are various formats for tables, depending upon the information you wish to include. So, be thorough and provide a table number and title (the latter should be italicized). Tables can be single or double-spaced.

Be sure to mention x- and y-axes clearly. Underneath the figure provide a label and brief caption. The figure caption typically includes variables and units of measurements. Also, include error bars in your bar graphs, and note what the bars represent in the figure caption – Error bars represent one standard error above and below the mean.

VI. In-Text Citation:

VII. Secondary Source:

It is a term used to describe material that is cited in another source. Avoid using secondary sources in your papers. Try to find the primary source and read it before citing in your work. However, if you must mention a secondary source, refer to the APA style paper example below:

Primary source author’s last name (as cited in secondary source author’s last name, year) argued that…

Research paper basics: apa style.

Published September 3, 2021 Submitted by: Anna

 Research Guide: APA Format

According to the American Psychological Association , APA Style “originated in 1929, when a group of psychologists, anthropologists, and business managers convened and sought to establish a simple set of procedures, or style rules, that would codify the many components of scientific writing to increase the ease of reading comprehension.” Similar to other writing styles, APA style concerns itself with elements including but not limited to:

APA style is most often used by writers in the behavioral and social science fields such as psychology, sociology and social work. Examples of papers that might use APA style format are empirical studies, literature reviews, theoretical articles, methodological articles and case studies.

Where Do I Start?

Some basic elements of a paper written in APA style would include:

All public computers at The Library have Microsoft Word. A reference librarian or computer assistant can help you adjust the settings for fonts, margins, indents, and more.

What are the parts of an APA Style Research Paper?

APA papers require title pages. Your title page will first include your running head (the title of your paper) along with the proper title of the paper, your name, and your school or professional affiliation and will be double-spaced. Your running head will appear flush left at the top of the page as follows:

        Running head: TITLE OF YOUR PAPER (capital letters)

Page number 1 will be flush right of the running head.

(Note: Your title page is the only page that will include the words “running head” before the title.)

Then type your complete title in uppercase and lowercase letters (APA recommends no more than 12 words in length). Your title is allowed to take up more than one line. Beneath the title, type your name as follows: first name, middle initial(s), last name. Beneath the author’s name, type the institutional affiliation , will most likely be where your research was conducted (school).

Begin a new page. Your abstract page should already have your running header flush left at the top and page number “2” at the top flush right. On the first line of this new page, center the word “Abstract” (no bold, underline or italics). On the next line (do not indent), write a brief summary of the key points of your paper. You might include your research methods, questions, participants, results, data analysis and conclusions. The abstract should be a 150-250 word double-spaced single paragraph.

You can also include a keywords list beneath your abstract. Beneath your summary, indent once and type “Keywords:” (in italics) and then list keywords from your paper separated by commas.

The body of your paper should maintain the 12 pt. readable font, doubled-spaced, with the running head and page number at the top of each page. First person point of view is allowed when discussing your research steps and methods (“I calculated…”). Active voice is preferred over passive (“We interpreted the results” vs. “The results were interpreted”). Be specific in your descriptions and explanations. Go heavy but remain accurate on details of your findings. Avoid bias in your word choices and avoid poetic and figurative language. Instead, use simple adjectives and plain language so that your reader won’t mistake your meaning.

In APA style, your list of citations is called your “References.” Your reference list will appear at the end of your paper on its own page(s). It allows your readers to locate any source you cite in the body of your paper. Label your list “References” at the top of your list, centered (do not bold, underline or italicize). Your reference page will be double-spaced just like the rest of the paper. More specifics on how to format your References page will follow.

How Do I Cite My Sources?: Your References and In-Text Citations

APA Style requires you to cite the sources of your paper in two ways: by maintaining a References page and by including in-text citations.

References Page

The References page appears at the end of your paper. It is a list of every source you used or consulted within the body of your paper. The References page allows your readers to locate and retrieve exactly where you found your information if need be.

APA citation style has some basic form guidelines. For example, authors are listed alphabetically by last name, followed by their initials. Publication year goes between parentheses, followed by a period. For the title of the article, only the first word and proper nouns in the title are capitalized. The periodical title has normal capitalization followed by the volume number which is italicized along with the title. Then list page numbers of the article you reference in your paper. If you accessed an article online, a URL link is needed in the citation.

Here is a sample article citation:

Harlow, H. F. (1983). Fundamentals for preparing psychology journal

     articles. Journal of Comparative and Physiological Psychology,

     55, 893-896.

The exact information included in each citation as well as the format might vary depending on what source material you are citing, whether it be an article in a magazine, newspaper, journal, book or electronic source. The Publication Manual of the American Psychological Association explains these differences and specifics in Chapter 6: Crediting Sources.

In-Text Citations

In-text citations are words and numbers enclosed in parentheses throughout your paper after you quote or paraphrase someone else’s idea. The idea is to give credit where credit is due and to avoid plagiarism. APA style uses the “author-date” method of in-text citation. This means that the author’s last name and the year of publication for the source you are citing should appear in the body of your paper, for example, like this: (Smith, 2009), and a complete reference should appear on your References list at the end of the paper. Here are some further in-text citation tips:

Additional Help

There are several sources online that can help with issues that might arise when working with APA style formatting.

These websites are maintained by universities and are pretty reliable, however it is important to double check that you have the proper format by cross-referencing your citations with the Publication Manual of the American Psychological Association.

Becoming academically successful is not easy. In order to accurately and academically write about research results, you have to get acquainted with the rules of formatting a research paper or you can pay for custom research paper according to all APA formatting rules.

APA style is used worldwide for formatting and referencing sources used in research papers. APA formatting guidelines allow authors to efficiently organize their arguments and properly credit secondary literature to avoid plagiarism. Furthermore, the APA style improves comprehension for readers as the consistency it provides allows readers to focus on the contents of the paper instead of its presentation. The APA style guidelines are updated according to feedback from researchers and educational stakeholders. The APA style guidelines provide authors with a credible and well-recognized format, which makes their paper well-organized and easy to read.

What is APA?

A set of guidelines when writing a piece of literature not only makes the organization of arguments easier but also enables better readability. The APA style has been created by the American Psychological Association as a language to be used in research papers and higher education. An APA research paper is formatted according to an expected standard and sources  are cited correctly to avoid plagiarism.

The APA research paper format allows writers to be consistent with their writing, which increases efficiency concerning research and organizing arguments.

Using APA in-text citations and references in the bibliography can prevent writers from accidental plagiarism. Besides enabling the organization of ideas and preventing plagiarism, using APA provides writers with credibility as the use of APA style proves that one can 'speak' the language of academia. Following APA style provides writers with a predictable format to organize their ideas and provides readers with easier comprehension. Knowing how to use APA format is also key. In addition, you can always get a research paper written for you.

The latest APA style in use is the 7th Edition, which was published in 2020. Several changes were made in this edition to make the format easier to use for educational stakeholders. Some of the pertinent changes include alterations to formatting and citations. The 7th edition has recommended different cover pages for professionals and students. Student papers also do not require a running head in the current edition, and professional papers' running head does not require the label "running head". Furthermore, level three, four, and five headings have been modified. The recent edition is also more lenient concerning font choices, and a variety of fonts are acceptable given one is used consistently throughout the paper. Several changes have been made to the reference list and the APA format citation. Writers must follow the guidelines of the latest APA style unless specified otherwise. If students encounter difficulties with this type of writing, they usually use help of research paper services .

General Requirements for APA Format

Given that the APA style is usually used in the literature about the scientific field, the authors must remain concise and precise. Professional language is key, and the main ideas should be written clearly. Authors should avoid irrelevant details. Overall, the length of APA style papers should be kept to the minimum while encompassing the author's ideas.

APA formatting rules call for papers to be typed on a standard-sized paper of 8.5 inches times 11 inches. The text in the paper should be double-spaced with a one-inch margin on all four sides. The font used should be easily readable; however, 12-point Times New Roman is generally used . Students are to follow these standard guidelines unless specifically informed otherwise by their professors. 

The 7th edition calls for a different APA title page research paper format for students and professionals. A student paper will include the title of the paper, the author's name, institutional affiliation, course name, and number, the name of the instructor, and the due date of the assignment. The title should be centered and in boldface and should be one or two lines long. The title can contain uppercase and lowercase letters. The title should be concise and writers should avoid using irrelevant words or abbreviations. Similar to the rest of the paper, the title page should also be double-spaced. In a professional paper, the title should be followed by the institutional affiliation with the location where the research was conducted. These papers also include an author's note, which is divided into several paragraphs. The first paragraph consists of the authors' name and ORCID ID (omitted if the author(s) do not have an ORCID ID). Any deaths of authors or changes in affiliation are written in the second paragraph, and the third paragraph includes any acknowledgments and disclosures. Student papers do not require an author's note. 

Running heads are not required for student papers, however, professional papers include a running head. The “running head” label has been omitted in the APA’s 7th edition  A running head is flush left of the paper and should not exceed more than 50 characters including spacing and punctuation. Furthermore, the running head is in all uppercase . In both types of papers, the header has the page number flush right.

The table of contents is an important part of an academic paper as it provides readers with a roadmap for the paper. Adding a table of content is not compulsory in APA, but is recommended for lengthier papers. The table of contents should be in the same font and double-spaced such as the paper.

The table of contents should begin with a centered heading of "Table of Contents" in boldface at the top of the page.

All main headings are flushed to the left, and subheadings are indented by five spaces. Lower level headings can also be included, but they should be additionally indented. All headings should be in the title case, and dotted lines should be included between the headings and their page number for easier readability. The table of contents will include all pages, including preliminary and supplementary, and should not exceed two pages. Table of contents makes the paper easier to navigate through, which in turn allows the readers to focus on the content of the paper, one of the key purposes of using APA style.

A solid outline forms the foundation of a well-organized paper. An APA paper is broadly divided into three parts, namely, the introduction, the body, and the conclusion. The introduction provides background for the paper and contains the thesis statement. In the body, the writer presents the main points that support the thesis statement. The conclusion provides the overall summary of the points made in the body and justifies how the paper supports the thesis statement. The references list follows the conclusion. For research papers, an abstract should also be added before the introduction. All research papers may not follow this exact outline, but this outline serves as a general guideline. 

The abstract is written after the title page. Although generally overlooked, the abstract serves as a pivotal part of any well-written research paper. The purpose of an abstract is to provide the readers with a summary of the research paper. Being the first thing the reader sets their sight upon in the research paper, the abstract should inform the reader what the research paper is about and what they can expect. An abstract is a single paragraph in block format. Moreover, the abstract is written on its page titled "abstract", which is centered. Given that the abstract is required to be 150 to 250 words, each sentence should be packed with information for maximum impact. The information in the abstract should be structured according to the paper. writers should ensure that the abstract is succinct yet well-organized and packed with information. 

An APA-style paper broadly consists of an introduction, a body, and a conclusion. This part of the paper contains indented paragraphs.

The introduction is written after the title of the paper, which is placed on the top of the page, centered. The introduction paragraph is not labeled. According to Hamilton (n.d.), the introduction of an APA-style paper is one of the most difficult components to write.

The purpose of the introduction is to provide writers with a critical overview and summary of empirical knowledge to define why the researchers chose to conduct the study.

The first line of the introduction is crucial as it can either cause the readers to continue reading the paper or otherwise. Therefore, the first line should "hook" the readers by being something interesting and thought-provoking. The introduction begins by broadly exploring the topic area and further narrows towards the hypothesis or thesis statement. References may be used in the introduction of research papers. Nevertheless, the use of direct quotes should be avoided. The introduction 'introduces' the paper to the readers and contains the hypothesis or thesis statement, making it critical for the paper.

The body contains the main points of the paper. In the case of a scientific research paper, the body will begin with the Method. All main headings of the body should be centered and in boldface. Albeit the Method section is quite straightforward, it must be precise and comprehensive to ensure that any other researcher can replicate the method used in the research paper exactly. The Method section can further be divided into Participants, Materials (and/or Apparatus), and Procedure sections. These sections will be labeled in boldface and flush left. Following the Method section will be the Results section. This section contains the methods used for the analysis of the data and the results so obtained. Researchers may also use tables and graphs to visually present the data to improve comprehension. The next section is the Discussion in which the researcher(s) interpret the data and compare them with existing literature concerning the topic. The Discussion section can be deemed as the opposite of the introduction concerning how it is organized. That is, it begins with specific information and further broadens. Limitations and scope for further research may be included in this section. The concluding paragraph of the study reiterates the need for the study and how it has added to existing literature. The above-mentioned outline for a research paper is for mainly scientific fields; APA format is used in several types of papers and should be outlined accordingly. 

The APA format reference page consists of a detailed list containing information regarding the sources used throughout the paper. This section begins on a new page titled "References", which is centered and on top of the page. The first line of the reference is flush left with the rest of the lines indented. The references are arranged alphabetically and are double-spaced. Books and journal titles are italicized, and the punctuation and capitalization used in the source are retained even if they are not standard. The format of the references should follow the guidelines outlined in the latest edition of APA format. The reference page is of utmost importance as it credits the sources used in the paper; if the sources are improperly credited or not credited at all, the author of the research paper loses credibility and risks plagiarism.

Guides for Writing in APA Format

APA referencing can be divided into two components: reference list and in-text citation. The core elements of an APA citation format are author rules, date rules, title rules, publisher rules, and the "Retrieved from…URL" if the source is found online. The reference begins with the author's last name followed by a comma and then his or her initials. Commas are used to separate multiple authors, and an ampersand is used before the name of the last author. If the source contains authors with the same surname and initial, their name should be added next to their initials in square brackets. Following the authors' name, the date when the source was published is written. In case the date is missing, "n.d." is written. The format of the title of the source differs depending on what is being referenced. For example, good titles for research papers require the proper nouns and the first word to be capitalized. The periodical title is italicized and written with normal capitalization. The volume number follows the title. Subsequently, the page numbers that were accessed in the article are mentioned . In Publisher rules, if the location of the publisher is in the US, the name of the city and the two-letter state code is written. Otherwise, the name of the city and the country are written for publishers located outside of the US . Following the correct format for the APA reference page is requisite.

Besides the above-mentioned rules, APA 7th edition has introduced a few more guidelines on how to write a paper in proper APA format. In case a source contains more than 20 authors, the names of the authors after the 19th author should be replaced by an ellipsis followed by the name of the last author. Furthermore, entries that include DOI do not require the label “DOI:”. The phrase “Retrieved from” when citing online sources should only be used if the retrieval date is also stated. Writers must use the latest updates in the APA paper format to remain current with their formatting.

The APA in-text citations are used within the paper. The APA style utilizes the “author-date” method, that is, the author’s last name followed by a comma and then the year the source was published are written in parenthesis. An in-text citation is used when information from a source is paraphrased or directly quoted. In-text citations are imperative for properly crediting sources and avoiding plagiarism.

Know how to structure your paper

PapersOwl editors can also format your paper according to your specific requirements.

In a research paper in APA format, abbreviations should be used sparingly. Excessive use of abbreviations can make the comprehension of the paper difficult for the reader, which is the opposite of what one aims to achieve when writing a research paper. If an abbreviation will be used less than three times in the paper, it is better to expand it each time. If abbreviations are to be used, periods are not required between each alphabet. For unfamiliar abbreviations, spell it out the first time it is used, and for abbreviations present in the dictionary, spell them out is not essential. For units of measurement, the abbreviation may be used when next to a number but should be spelled out if being used by itself. Abbreviations should be used judiciously in an APA-style research paper to ensure that they do not impede easy comprehension. 

In APA, the golden rule for using numbers is to write out numbers less than 10 in text and leave numbers above as is, for example:

14 kilograms

seven individuals

However, some exceptions apply such as number can be left as it is in tables, in case of measurements, when displaying a math equation, or when mentioning time and age. It is better to write numbers out in text when starting a sentence with a number, in the case of a fraction, or when using a commonly used phrase or word. Overall, the purpose of these guidelines when using numbers is to enhance comprehension and maintain consistency.

In APA style, general rules for punctuation are applicable. Writers should keep some pertinent guidelines in mind. One space is applicable after most punctuation marks. Moreover, the Oxford comma should be used in APA style format. No space should be placed after em dashes and no space should be applied on either side of an en dash. In most cases, the APA style follows universal punctuation and grammar rules. 

Usage of Graphics (Photos, Tables, and Figures) in APA Format

Graphics in APA should be numbered according to how they appear in the paper. Additionally, the graphic should provide new information and not reinstate what has already been written. When using tables, the information should be:

12pt font and single or double-spaced.

The spacing should be consistent across all tables.

All headings should be centered and information should be left-aligned (indented if more than one line).

In the case of photographs, they should be black and white. Moreover, if adapted or reproduced information is used, it should be cited. 

Formats such as APA serve as an essential element in the field of academia. A set of guidelines that are recognized worldwide relieves the effort required to format a paper for the authors and improves readability for readers. Furthermore, knowing how to start research paper amd how to format APA paper allows researchers to properly credit secondary sources to avoid plagiarism.

Paper Format

Consistency in the order, structure, and format of a paper allows readers to focus on a paper’s content rather than its presentation.

To format a paper in APA Style, writers can typically use the default settings and automatic formatting tools of their word-processing program or make only minor adjustments.

The guidelines for paper format apply to both student assignments and manuscripts being submitted for publication to a journal. If you are using APA Style to create another kind of work (e.g., a website, conference poster, or PowerPoint presentation), you may need to format your work differently in order to optimize its presentation, for example, by using different line spacing and font sizes. Follow the guidelines of your institution or publisher to adapt APA Style formatting guidelines as needed.

Citing Your Sources

When you use ideas that are not your own, it is important to credit or cite  the author(s) or source, even if you do not quote their idea or words exactly as written. Citing your sources allows your reader to identify the works you have consulted and to understand the scope of your research. There are many different citation styles available. You may be required to use a particular style or you may choose one.

One of the commonly used styles is the  APA (American Psychological Association) Style.  

APA style stipulates that authors use brief references in the text of a work with full bibliographic details supplied in a Reference List (typically at the end of your document). In text, the reference is very brief and usually consists simply of the author's last name and a date.For example:

...Sheep milk has been proved to contain more nutrients than cow milk (Johnson, 2005).

In a Reference list, the reference contains full bibliographic details written in a format that depends on the type of reference. Examples of formats for some common types of references are listed below. For additional information, visit the University of Arkansas libraries webpage on citing your sources . Another useful web-site on this topic is here.
