An appendix contains supplementary material that is not an essential part of the text itself but which may be helpful in providing a more comprehensive understanding of the research problem or it is information that is too cumbersome to be included in the body of the paper. A separate appendix should be used for each distinct topic or set of data and always have a title descriptive of its contents.

Importance of...

Appendices are always supplementary to the research paper. As such, your study must be able to stand alone without the appendices, and the paper must contain all information including tables, diagrams, and results necessary to understand the research problem. The key point to remember when including an appendix or appendices is that the information is non-essential; if it were removed, the reader would still be able to  comprehend the significance, validity , and implications of your research.

It is appropriate to include appendices for the following reasons:

• Including this material in the body of the paper that would render it poorly structured or interrupt the narrative flow;
• Information is too lengthy and detailed to be easily summarized in the body of the paper;
• Inclusion of helpful, supporting, or useful material would otherwise distract the reader from the main content of the paper;
• Provides relevant information or data that is more easily understood or analyzed in a self-contained section of the paper;
• Can be used when there are constraints placed on the length of your paper; and,
• Provides a place to further demonstrate your understanding of the research problem by giving additional details about a new or innovative method, technical details, or design protocols.

Structure and Writing Style

I.  General Points to Consider

When considering whether to include content in an appendix, keep in mind the following:

• It is usually good practice to include your raw data in an appendix, laying it out in a clear format so the reader can re-check your results. Another option if you have a large amount of raw data is to consider placing it online [e.g., on a Google drive] and note that this is the appendix to your research paper.
• Any tables and figures included in the appendix should be numbered as a separate sequence from the main paper . Remember that appendices contain non-essential information that, if removed, would not diminish a reader's ability to understand the research problem being investigated. This is why non-textual elements should not carry over the sequential numbering of non-textual elements in the body of your paper.
• If you have more than three appendices, consider listing them on a separate page in the table of contents . This will help the reader know what information is included in the appendices. Note that some works list appendices in the table of contents before the first chapter while other styles list the appendices after the conclusion but before your references. Consult with your professor to confirm if there is a preferred approach.
• The appendix can be a good place to put maps, photographs, diagrams, and other images , if you feel that it will help the reader to understand the content of your paper, while keeping in mind the study should be understood without them.
• An appendix should be streamlined and not loaded with a lot information . If you have a very long and complex appendix, it is a good idea to break it down into separate appendices, allowing the reader to find relevant information quickly as the information is covered in the body of the paper.

II.  Content

Never include an appendix that isn’t referred to in the text . All appendices should be summarized in your paper where it is relevant to the content. Appendices should also be arranged sequentially by the order they were first referenced in the text [i.e., Appendix 1 should not refer to text on page eight of your paper and Appendix 2 relate to text on page six].

There are very few rules regarding what type of material can be included in an appendix, but here are some common examples:

• Correspondence -- if your research included collaborations with others or outreach to others, then correspondence in the form of letters, memorandums, or copies of emails from those you interacted with could be included.
• Interview Transcripts -- in qualitative research, interviewing respondents is often used to gather information. The full transcript from an interview is important so the reader can read the entire dialog between researcher and respondent. The interview protocol [list of questions] should also be included.
• Non-textual elements -- as noted above, if there are a lot of non-textual items, such as, figures, tables, maps, charts, photographs, drawings, or graphs, think about highlighting examples in the text of the paper but include the remainder in an appendix.
• Questionnaires or surveys -- this is a common form of data gathering. Always include the survey instrument or questionnaires in an appendix so the reader understands not only the questions asked but the sequence in which they were asked. Include all variations of the instruments as well if different items were sent to different groups [e.g., those given to teachers and those given to administrators] .
• Raw statistical data – this can include any numerical data that is too lengthy to include in charts or tables in its entirety within the text. This is important because the entire source of data should be included even if you are referring to only certain parts of a chart or table in the text of your paper.
• Research instruments -- if you used a camera, or a recorder, or some other device to gather information and it is important for the reader to understand how, when, and/or where that device was used.
• Sample calculations – this can include quantitative research formulas or detailed descriptions of how calculations were used to determine relationships and significance.

NOTE:   Appendices should not be a dumping ground for information. Do not include vague or irrelevant information in an appendix; this additional information will not help the reader’s overall understanding and interpretation of your research and may only distract the reader from understanding the significance of your overall study.

ANOTHER NOTE :   Appendices are intended to provide supplementary information that you have gathered or created; it is not intended to replicate or provide a copy of the work of others. For example, if you need to contrast the techniques of analysis used by other authors with your own method of analysis, summarize that information, and cite to the original work. In this case, a citation to the original work is sufficient enough to lead the reader to where you got the information. You do not need to provide a copy of this in an appendix.

III.  Format

Here are some general guideline on how to format appendices . If needed, consult the writing style guide [e.g., APA, MLS, Chicago] your professor wants you to use for more detail:

• Appendices may precede or follow your list of references.
• Each appendix begins on a new page.
• The order they are presented is dictated by the order they are mentioned in the text of your research paper.
• The heading should be "Appendix," followed by a letter or number [e.g., "Appendix A" or "Appendix 1"], centered and written in bold type.
• If there is a table of contents, the appendices must be listed.
• The page number(s) of the appendix/appendices will continue on with the numbering from the last page of the text.

Writing Tip

Consider Putting Your Appendices Online

Appendices are useful because they provide the reader with information that supports your study without breaking up the narrative or distracting from the main purpose of your paper. If you have a lot of raw data or information that is difficult to present in textual form, consider uploading it to an online site. This prevents your paper from having a large and unwieldy set of appendices and it supports a growing movement within academe to make data more freely available for re-analysis. If you do create an online portal to your data, note it prominently in your paper with the correct URL and access procedures if it is a secured site.

• How To Write A Research Paper Appendix: A Step-by-Step Guide

Think of appendices like bonus levels on your favorite video game. They are not a major part of the game, but they boost your points and they make the game worthwhile. 

Appendix are important facts, calculations, or data that don’t fit into the main body of your research paper. Having an appendix gives your research paper more details, making it easier for your readers to understand your main ideas.

Let’s dive into how to create an appendix and its best practices.

Understanding the Purpose of an Appendix

If you’re looking to add some extra depth to your research, appendices are a great way to do it.  They allow you to include extremely useful information that doesn’t fit neatly into the main body of your research paper, such as huge raw data, multiple charts, or very long explanations.

Think of your appendix as a treasure chest with different compartments. You can include different information including, extra data, surveys, graphs, or even detailed explanations of your methods. You can fit anything too big or detailed for the main paper in the appendix.

Planning Your Appendix

Before you dive into making your appendix, it’s a good idea to plan things out; think of it as drawing a map before going on an adventure. 

You want your appendix to be organized and provide more context to your research. Not planning it will make the process time-consuming and make the appendix confusing to people reading your research paper.

How to Decide What to Include in Your Research Paper

You have to sort through the content that you will include in your appendix. Think of what your readers need to know to understand your key points. Anything that’s overly detailed, off-topic, or clutters up your paper is a good candidate for your appendix.

Tips for Organizing Your Appendix

Once you’ve figured out what to put in your appendix, it’s time to organize it. Your appendix is a place to add extra information, but it shouldn’t be cluttered or confusing to your readers. Instead, it should make your research paper easier to understand.

Use clear headings, labels, and even page numbers to help your readers find the information they need in the appendix. This way, it’s not a jumbled mess, but a well-organized part of your research paper

Formatting Guidelines

Yes, your appendix must be formatted. Most of the time, you’ll want to keep the font and margin sizes consistent with your main paper. 

However, some universities and journals may have specific guidelines for appendix formatting. Verify if your institution has special guidelines, if they do, follow them, if they don’t use the same format as your main text.

Here’s a typical breakdown of how to format your appendix:

(1) Labeling and Titling 

If you have different types of information in your appendix, use letters to label them, such as “Appendix A” and “Appendix B”. Then, give each appendix a title that explains the information inside it. 

For example, if the first section of your appendix contains raw survey data, you could call it “Appendix A (Survey Data of People Living with Diabetes Under 18 in Texas)”. If the second section of your appendix contains charts, you could call it “Appendix B (The Effect of Sugar Tax in Curbing Diabetes in Children and Young Adults)”.

(2) Numbering Tables, Figures, and More 

If you have tables, figures, or other things in your appendix, number them like a list. For example, “Table A1,” “Figure A1,” and more. This numbering helps your readers know what they’re looking at, sort of like chapters in a book.

Creating Tables and Figures

Using tables and figures helps you organize your data neatly in your appendix. Here’s a step-by-step guide to creating tables and figures in your appendix:

Choose the Right Format for Your Appendix Data

Before creating tables or figures, you need to pick the right format to display the information. Think about what makes your data most clear and understandable. 

For example, a table is better for detailed numbers, while a graph is great for showing trends. The right format makes your information easy to grasp and makes your paper look organized.

How to Create Tables in Your Appendix

You can use a spreadsheet program (like Excel or Google Sheets) to create tables to arrange information neatly. Make sure to give your table a clear title so readers know what it’s about.

Here’s a step-by-step guide to creating tables with a spreadsheet program:

• Open Google Sheets/Excel : Access Google Sheets or Excel through the web or download the app
• Open a New Spreadsheet or Existing File : Create a new spreadsheet or open an existing one where you want to insert a table.
• Select Data : Click and drag to select the data you want to include in the table.
• Insert Table : Once your data is selected, go to the “Insert” menu, then select “Table.
• Create Table : A dialog box will appear, confirming the selected data range. Make sure the “Use the first row as headers” option is checked if your data has headers. Click “Insert .”
• Customize Your Table : After inserting the table, you can customize it by adjusting the style, format, and other table properties using the “Table” menu in Google Sheets or Excel.

You can use software like PowerPoint, Google Slides, or graphic design tools to create them. If you have a chart or graph, make sure it’s easy to understand and add a title or labels to explain it. 

You can use the editing tools for images to change the size and other aspects of the image.

Including Raw Data

The major reasons for including raw data in your appendix are transparency and credibility. Raw data is like your research recipe; it shows exactly what you worked with to arrive at your conclusions.

Raw data also provides enough information to guide researchers in replicating your study or getting a deeper understanding of your research.

Formatting and Presenting Raw Data 

Formatting your raw data makes it easy for anyone to understand. You can use tables, charts, or even lists to display your data. For example, if you did a survey, you could put the survey responses in a table with clear headings.

When presenting your raw data, clear organization is your best friend. Use headings, labels, and consistent formatting to help your readers find and understand the data. This keeps your appendix from becoming a confusing puzzle.

Citing Your Appendix

Referencing your appendix in the main text gives readers a full picture of your research while they’re reading- They don’t have to wait until the end to figure out important details of your research.

Unlike actual references and citations, citing your appendix is a very straightforward process. You can simply say, “See Appendix A for more details.”

In-Text Citations for Appendix Content

If you would like to cite information in your appendix, you usually mention the author, year, and what exactly you’re citing. This allows you to give credit to the original creator of the content, so your readers know where it came from.

For instance, if you included a chart from a book in your appendix, you’d say something like (Author, Year, p. X). Keep in mind that there are different citation styles (APA, MLA, Chicago, and others), so your appendix may look a little different.

Proofreading and Editing

Proofreading and editing your appendix is just as important as proofreading and editing the main body of your paper. A poorly written or formatted appendix can leave a negative impression on your reader and detract from the overall quality of your work. 

Make sure that your appendix is consistent with the main text of your paper in terms of style and tone unless otherwise stated by your institution. Use the same font, font size, and line spacing in the appendix as you do in the main body of your paper. 

Your appendix should also be free of errors in grammar, spelling, punctuation, and formatting.

Tips for Checking for Errors in Formatting, Labeling, and Content

Here are some tips for checking for errors in formatting, labeling, and content in your appendix:

• Formatting : Make sure that all of the elements in your appendix are formatted correctly, including tables, figures, and equations. Check the margins, line spacing, and font size to make sure that they are consistent with the rest of your paper.
• Labeling : All of the tables, figures, and equations in your appendix should be labeled clearly and consistently. Use a consistent numbering system and make sure that the labels match the references in the main body of your paper.
• Content : Proofread your appendix carefully to catch any errors in grammar, spelling, punctuation, and content. You can use grammar editing tools such as Grammarly to help you automatically detect errors in your context.

Appendix Checklist

Having an appendix checklist guarantees a well-organized appendix and helps you spot and correct any overlooked mistakes.

Here’s a checklist of key points to review before finalizing your appendix:

• Is all of the information in the appendix relevant and necessary?
• Is the appendix well-organized and easy to understand?
• Are all the tables, numbers, and equations clearly labeled?
• Is the appendix formatted correctly and consistently with the main body of the paper?
• Is the appendix free of errors in grammar, spelling, punctuation, and content?

Sample Appendix

We have discussed what you should include in your appendix and how to organize it. Let’s take a look at what a well-formatted appendix looks like:

Appendix A. (Raw Data of Class Scores)

The following table shows the raw data collected for the study.

How the Sample Appendix Adheres to Best Practices

• The appendix is labeled clearly and concisely as “Appendix A. (Raw Data of Class Score).”
• The appendix begins on a new page.
• The appendix is formatted consistently with the rest of the paper, using the same font, font size, and line spacing.
• The table in the appendix is labeled clearly and concisely as “Table A1.”
• The table is formatted correctly, with consistent column widths and alignment.
• The table includes all of the necessary information, including the participant number, age, gender, and score.
• The appendix is free of grammar, spelling, and punctuation errors.

Having an appendix easily makes your research paper impressive to reviewers, and increases your likelihood of achieving high grades or journal publication.  It also makes it easier for other researchers to replicate your research, allowing you to make a significant contribution to your research field.

Ensure to use the best practices in this guide to create a well-structured and relevant appendix. Also, use the checklist provided in this article to help you carefully review your appendix before submitting it.

Appendix in Research Paper

Appendix in a research paper is a section located at the end of the document that contains supplementary material that is not essential to the main body of the research paper but is helpful to the reader in understanding the research study.

This supplementary material can include raw data, statistical analyses, graphs, charts, questionnaires , maps, and other supporting documents or evidence that are referred to in the main body of the paper or that are necessary for the reader to have a complete understanding of the research study.

How to Write Appendix in Research Paper

Here are the steps on how to write an appendix in a research paper:

• Determine what material you need to include in the appendix. This can include charts, graphs, images, tables, raw data, survey questionnaires, and any other material that supports your research but is not included in the main body of the paper.
• Organize the material in a logical and coherent manner . If you have multiple items to include, it is helpful to number them or use lettered headings (e.g., Appendix A, Appendix B) to make it easier for readers to find specific information.
• Title the appendix section appropriately. The title should reflect the content of the appendix and be descriptive enough for readers to understand what is included.
• If necessary, provide a brief introduction or explanation for the material in the appendix. This can help readers understand why the information is relevant to your research.
• Place the appendix section after the main body of the paper and before the reference section.
• Make sure to refer to the appendix in the main body of the paper . This can be done by including a parenthetical reference (e.g., see Appendix A) or by including a reference in the text (e.g., refer to Table 1 in Appendix A).
• Ensure that the formatting of the appendix is consistent with the rest of the paper, including font size and style, margins, and spacing.
• If you have multiple appendices, provide a table of contents at the beginning of the appendix section to make it easier for readers to navigate.

Types of Appendix in Research Paper

In a research paper, there are two types of appendix:

Supplementary material

This type of appendix includes additional information that supports the main content of the research paper, but which is not essential to understanding the main argument. Supplementary material may include graphs, tables, figures, or lengthy data sets.

This type of appendix includes raw data that has been collected for the research study. It provides readers with the opportunity to analyze and verify the data used in the research paper. Raw data can be presented in various formats such as spreadsheets, tables, and graphs.

In the main body of your research paper, it’s important to provide clear and concise information that supports your argument and conclusions . However, after doing all that research, you’ll often find that you have a lot of other interesting information that you want to share with your reader.

While including it all in the body would make your paper too long and unwieldy, this is exactly what an appendix is for.

As a rule of thumb, any detailed information that is not immediately needed to make your point can go in an appendix. This helps to keep your main text focused but still allows you to include the information you want to include somewhere in your paper.

Prevent plagiarism, run a free check.

An appendix can be used for different types of information, such as:

• Supplementary results : Research findings  are often presented in different ways, but they don’t all need to go in your paper. The results most relevant to your research question should always appear in the main text, while less significant results (such as detailed descriptions of your sample or supplemental analyses that do not help answer your main question), can be put in an appendix.
• Statistical analyses : If you conducted statistical tests using software like Stata or R, you may also want to include the outputs of your analysis in an appendix.
• Further information on surveys or interviews : Written materials or transcripts related to things such as surveys and interviews can also be placed in an appendix.

You can opt to have one long appendix, but separating components (like interview transcripts, supplementary results, or surveys) into different appendices makes the information simpler to navigate.

Here are a few tips to keep in mind:

• Always start each appendix on a new page.
• Assign it both a number (or letter) and a clear title, such as ‘Appendix A. Interview transcripts’. This makes it easier for your reader to find the appendix, as well as for you to refer back to it in your main text.
• Number and title the individual elements within each appendix (e.g., ‘Transcripts’) to make it clear what you are referring to. Restart the numbering in each appendix at 1.

It is important that you refer to each of your appendices at least once in the main body of your paper. This can be done by mentioning the appendix and its number or letter, either in parentheses or within the main part of a sentence. It is also possible to refer to a particular component of an appendix.

Appendix B presents the correspondence exchanged with the fitness boutique. Example 2. Referring to an appendix component These results (see Appendix 2, Table 1) show that …

It is common to capitalise ‘Appendix’ when referring to a specific appendix, but it is not mandatory. The key is just to make sure that you are consistent throughout your entire paper, similarly to consistency in capitalising headings and titles in academic writing.

However, note that lowercase should always be used if you are referring to appendices in general. For instance, ‘The appendices to this paper include additional information about both the survey and the interviews.’

The simplest option is to add your appendices after the main body of your text, after you finish citing your sources in the citation style of your choice . If this is what you choose to do, simply continue with the next page number. Another option is to put the appendices in a separate document that is delivered with your dissertation.

Remember that any appendices should be listed in your paper’s table of contents .

There are a few other supplementary components related to appendices that you may want to consider. These include:

• List of abbreviations : If you use a lot of abbreviations or field-specific symbols in your dissertation, it can be helpful to create a list of abbreviations .
• Glossary : If you utilise many specialised or technical terms, it can also be helpful to create a glossary .
• Tables, figures and other graphics : You may find you have too many tables, figures, and other graphics (such as charts and illustrations) to include in the main body of your dissertation. If this is the case, consider adding a figure and table list .

Checklist: Appendix

All appendices contain information that is relevant, but not essential, to the main text.

Each appendix starts on a new page.

I have given each appendix a number and clear title.

I have assigned any specific sub-components (e.g., tables and figures) their own numbers and titles.

My appendices are easy to follow and clearly formatted.

I have referred to each appendix at least once in the main text.

Your appendices look great! Use the other checklists to further improve your thesis.

An appendix contains supplementary material that is not an essential part of the text itself but which may be helpful in providing a more comprehensive understanding of the research problem and/or is information which is too cumbersome to be included in the body of the paper. A separate appendix should be used for each distinct topic or set of data and always have a title descriptive of its contents .

Importance of...

Your research paper must be complete without the appendices, and it must contain all information including tables, diagrams, and results necessary to address the research problem. The key point to remember when you are writing an appendix is that the information is non-essential; if it were removed, the paper would still be understandable.

It is appropriate to include appendices...

• When the incorporation of material in the body of the work would make it poorly structured or it would be too long and detailed and
• To ensure inclusion of helpful, supporting, or essential material that would otherwise clutter or break up the narrative flow of the paper, or it would be distracting to the reader.

Structure and Writing Style

I.  General Points to Consider

When considering whether to include content in an appendix, keep in mind the following points:

• It is usually good practice to include your raw data in an appendix, laying it out in a clear format so the reader can re-check your results. Another option if you have a large amount of raw data is to consider placing it online and note this as the appendix to your research paper.
• Any tables and figures included in the appendix should be numbered as a separate sequence from the main paper . Remember that appendices contain non-essential information that, if removed, would not diminish a reader's understanding of the overall research problem being investigated. This is why non-textual elements should not carry over the sequential numbering of elements in the paper.
• If you have more than three appendices, consider listing them on a separate page at the beginning of your paper . This will help the reader know before reading the paper what information is included in the appendices [always list the appendix or appendices in a table of contents].
• The appendix can be a good place to put maps, photographs, diagrams, and other non-textual elements , if you feel that it will help the reader to understand the content of your paper, but remembering that the paper should be understandable without them.
• An appendix should be streamlined and not loaded with a lot information . If you have a very long and complex appendix, it is a good idea to break it down into separate appendices, allowing the reader to find relevant information quickly.

II.  Contents

Appendices may include some of the following, all of which should be referred to or summarized in the text of your paper:

• Supporting evidence [e.g. raw data]
• Contributory facts or specialized data [raw data appear in the appendix, but with summarized data appearing in the body of the text].
• Sample calculations
• Technical figures, graphs, tables, statistics
• Detailed description of research instruments
• Maps, charts, photographs, drawings
• Letters, emails, and other copies of correspondance
• Questionnaire/survey instruments, with the results appearing in the text
• Complete transcripts of interviews
• Complete field notes from observations
• Specification or data sheets

NOTE:   Do not include vague or irrelevant information in an appendix; this additional information will not help the reader’s overall understanding and interpretation of your research and may only succeed in distracting the reader from understanding your research study.

III.  Format

Here are some general guideline on how to format appendices, but consult the writing style guide [e.g., APA] your professor wants you to use for the class, if needed:

• Appendices may precede or follow your list of references.
• Each appendix begins on a new page.
• The order they are presented is dictated by the order they are mentioned in the text of your research paper.
• The heading should be "Appendix," followed by a letter or number [e.g., "Appendix A" or "Appendix 1"], centered and written in bold.
• Appendices must be listed in the table of contents [if used].
• The page number(s) of the appendix/appendices will continue on with the numbering from the last page of the text.

• When to Use an Appendix
• What to Include
• Basic Rules

If you are writing a psychology paper for a class or for publication, you may be required to include an appendix in APA format. An APA appendix is found at the end of a paper and contains information that supplements the text but that is too unwieldy or distracting to include in the main body of the paper. 

APA format is the official writing style used by the American Psychological Association . This format dictates how academic and professional papers should be structured and formatted. 

Does Your Paper Need an APA Appendix?

Some questions to ask about whether you should put information in the body of the paper or in an appendix:

• Is the material necessary for the reader to understand the research? If the answer is yes, it should be in your paper and not in an appendix.
• Would including the information interrupt the flow of the paper? If the answer is yes, then it should likely appear in the appendix.
• Would the information supplement what already appears in your paper? If yes, then it is a good candidate for including in an appendix.

Your appendix is not meant to become an information dump. While the information in your appendices is supplementary to your paper and research, it should still be useful and relevant. Only include what will help readers gain insight and understanding, not clutter or unnecessary confusion.

What to Include in an APA Appendix

The APA official stylebook suggests that the appendix should include information that would be distracting or inappropriate in the text of the paper.

Some examples of information you might include in an appendix include:

• Correspondence (if it pertains directly to your research)
• Demographic details about participants or groups
• Examples of participant responses
• Extended or detailed descriptions
• Lists that are too lengthy to include in the main text
• Large amounts of raw data
• Lists of supporting research and articles that are not directly referenced in-text
• Materials and instruments (if your research relied on special materials or instruments, you might want to include images and further information about how these items work or were used)
• Questionnaires that were used as part of your research
• Raw data (presented in an organized, readable format)
• Research surveys

While the content found in the appendix is too cumbersome to include in the main text of your paper, it should still be easily presented in print format.

The appendices should always act as a supplement to your paper. The body of your paper should be able to stand alone and fully describe your research or your arguments.

The body of your paper should not be dependent upon what is in the appendices. Instead, each appendix should act to supplement what is in the primary text, adding additional (but not essential) information that provides extra insight or information for the reader. 

Basic Rules for an APA Appendix

Here are some basic APA appendix rules to keep in mind when working on your paper:

• Your paper may have more than one appendix.
• Each item usually gets its own appendix section.
• Begin each appendix on a separate page.
• Each appendix must have a title.
• Use title case for your title and labels (the first letter of each word should be capitalized, while remaining letters should be lowercase).
• If your paper only has one appendix, simply title it Appendix. 
• If you have more than one appendix, each one should be labeled Appendix A, Appendix B, Appendix C, and so on.
• Put the appendix label centered at the top of the page.
• On the next line under the appendix label, place the centered title of the appendix. 
• If you refer to a source in your appendix, include an in-text citation just as you would in the main body of your paper and then include the source in your main reference section.
• Each appendix may contain headings, subheadings, figures, and tables. 
• Each figure or table in your appendix should include a brief but explanatory title, which should be italicized. 
• If you want to reference your appendix within the text of your paper, include a parenthetical note in the text. For example, you would write (See Appendix A).

Formatting an APA Appendix

How do you format an appendix in APA? An APA appendix should follow the overall rules on how to format text. Such rules specify what font and font size you should use, the size of your margins, and the spacing of the text.

Some of the APA format guidelines you need to observe:

• Use a consistent font, such as 12-point Times New Roman or 11-point Calibri
• Double-space your text
• All paragraphs should be indented on the first line
• Page numbering should be continuous with the rest of your paper

The appendix label should appear centered and bolded at the top of the page. A descriptive title should follow and should also be bolded and centered. As with other pages in your paper, your APA format appendix should be left-aligned and double-spaced. Each page should include a page number in the top right corner. You can also have more than one appendix, but each one should begin on a new page.

Data Displays in an APA Appendix

When presenting information in an appendix, use a logical layout for any data displays such as tables or figures. All tables and figures should be labeled with the words “Table” or “Figure” (sans quotation marks) and the letter of the appendix and then numbered.

For example, Table A1 would be the first table in an Appendix A. Data displays should be presented in the appendix following the same order that they first appear in the text of your paper.

In addition to following basic APA formatting rules, you should also check to see if there are additional guidelines you need to follow. Individual instructors or publications may have their own specific requirements.

Where to Include an APA Appendix

If your paper does require an appendix, it should be the very last pages of your finished paper. An APA format paper is usually structured in the following way:

Your paper may not necessarily include all of these sections. At a minimum, however, your paper may consist of a title page, abstract, main text, and reference section. Also, if your paper does not contain tables, figures, or footnotes, then the appendix would follow the references.

Never include an appendix containing information that is not referred to in your text. 

A Word From Verywell

Writing a paper for class or publication requires a great deal of research, but you should pay special attention to your APA formatting. Each section of your paper, including the appendix section, needs to follow the rules and guidelines provided in the American Psychological Association’s stylebook.

General Research Paper Guidelines: Appendices

If you have some information you would like to include in your research but it could potentially be distracting to readers or inappropriate within the body of your research paper, you can always include supplemental information as an appendix to your work. An appendix or appendices should always be inserted after your Reference List; however, the appropriateness of appendix content really depends on the nature and scope of your research paper.

For a more in-depth review of what supplemental materials might be included in a social science appendix, be sure to review Section 2.14 “Appendices” (pp. 41-42) of your 7 th edition APA manual.

Appendices Formatting

APA 7 addresses appendices and supplemental materials in Section 2.14 and on page 41:

• The appendices follow the reference list.
• They are lettered "Appendix A," "Appendix B," "Appendix C," and so forth. If you have only one appendix, however, simply label it Appendix.
• Put figures and tables in separate appendices. The appendix title serves as the title for a table if it is the only table in the appendix.
• If you decide that certain figures and tables should appear in the same appendix, number them A1, A2, A3, and so forth, according to the appendix in which they appear.
• The materials in the appendix must not extend beyond the margins of the rest of the paper: Reduce the appendix materials as needed.

As a general guide, appendices are appropriate for any material that, if presented in the main body of the document, would unnecessarily interrupt the flow of the writing. Note that it is unlikely that you will use appendices in Walden course papers. For doctoral capstone studies, you might include some appendices with supplementary information.

How to Format An Appendix - Tutorial

• APA Appendices - JIBC Tip Sheet All you need to know about appendices in APA Style.

Information in this section is as outlined in the APA Publication Manual (2020), sections 2.14, 2.17, 2.24, and 7.6.

Appendices are used to include information that supplement the paper’s content but are considered distracting or inappropriate for the overall topic. It is recommended to only include an appendix if it helps the reader comprehend the study or theoretical argument being made. It is best if the material included is brief and easily presented. The material can be text, tables, figures, or a combination of these three.

Placement :

Appendices should be placed on a separate page at the end of your paper after the references, footnotes, tables, and figure. The label and title should be centre aligned. The contents of the appendix and the note should be left-aligned.

• If you are choosing to include tables and figures in your appendix, then you can list each one on a separate page or you may include multiple tables/figures in one appendix, if there is no text and each table and/or figure has its own clear number and title within the appendix.
• Tables and figures in an appendix receive a number preceded by the letter of the appendix in which it appears, e.g. Table A1 is the first table in Appendix A or of a sole appendix that is not labeled with a letter.

The follow elements are required for appendices in APA Style:

Appendix Labels:

Each appendix that you place in your paper is labelled “Appendix.” If a paper has more than one appendix, then label each with a capital letter in the order the appendices are referred to in your paper (“Appendix A” is referred to first, “Appendix B” is referred to second, etc).

• The label of the appendix should be in bold font, centre-aligned, follow Title Casing, and is located at the top of the page.
• If your appendix only contains one table or figure (and no text), then the appendix label takes the place of the table/figure number, e.g. the table may be referred to as “Appendix B” rather than “Table B1.”

Appendix Titles:

Each appendix should have a title, that describes its contents. Titles should be brief, clear, and explanatory.

• The title of the appendix should be in bold font, centre-aligned, follow Title Casing, and is one double-spaced line down from the appendix label.
• If your appendix only contains one table or figure (and no text), then the appendix title takes the place of the table/figure title. 

Appendix Contents:

• Left aligned and indented; written the same as paragraphs within the body of the paper
• Double-spaced and with the same font as the rest of the paper
• If the appendix contains a table and/or figure, then the table/figure number must contain a letter to correlate the table and/or figure to the appendix and not the body of the paper, e.g. “Table A1” rather than “Table 1” to clarify that the table appears in the appendix and not in the body of the paper.
• All tables and figures in an appendix must be mentioned in the appendix and numbered in order of mention. 
• All tables and figures must be aligned to the left margin, (not center aligned), and positioned after a paragraph break, preferably the paragraph in which they are referred to, with a double-spaced blank line between the table and the text. 
• Each table and figure should include a note afterwards to further explain the supplement or clarify information in the table or figure to your paper/appendix and can be general, specific, and probability. See “Table Notes” in the section “Table and Figures” above for more details.

Referring to Appendices in the Text:

In your paper, refer to every appendix that you have inserted. Do not include an appendix in your work that you do not clearly explain in relation to the ideas in your paper.

• In general, only refer to the appendix by the label (“Appendix” or “Appendix A” etc.) and not the appendix title.

Reprinting or Adapting:

If you did not create the content in the appendix yourself, for instance if you found a figure on the internet, you must include a copyright attribution in a note below the figure. 

• A copyright attribution is used instead of an in-text citation. 
• Each work should also be listed in the reference list. 

Please see pages 390-391 in the Manual for example copyright attributions.

"Material that supplements the content of the paper, but would be distracting or inappropriate to include in the body of the paper is to be placed in an appendix." This includes "materials that are relatively brief and that are easily presented in print format" ( Publication Manual of the APA: 6th edition , section 2.13; Publication Manual of the APA: 7th edition , section 2.14). Examples include "mathematical proofs, lists of words, a questionnaire used in the research, a detailed description of an apparatus used in the research, etc" ( Purdue OWL .)

An appendix (or appendices) follow the reference list. Use the following order for your paper:

• Abstract ( if required, start on a new page, numbered page 2)
• Text (start on a new page, numbered 3)
• References (start on a new page)
• Tables (start each on a new page)
• Figures (start each on a new page; include caption on page with figure)
• Appendices (start each on a new page)
• If only one appendix, label it Appendix
• If more than one appendix: label each one with a capital letter (Appendix A, Appendix B, etc.) in the order in which it is mentioned in the text
• Each appendix must have a title
• In the text, refer to appendices by their labels:

"produced the same results for both studies (see Appendices A and B for complete proofs)."

• Begin each appendix on a separate page
• At the top of the page, center the word Appendix and the identifying capital letters (A, B, etc.) in the order in which they are mentioned in the text.
• Center the title of the appendix using uppercase and lowercase letter on the next line
• Begin the text of the appendix flush left, followed by indented paragraphs.

What is an appendix in a paper

What is an appendix?

What type of information includes an appendix, the format of an appendix, frequently asked questions about appendices in papers, related articles.

An appendix is a section of a paper that features supporting information not included in the main text.

The appendix of a paper consists of supporting information for the research that is not necessary to include in the text. This section provides further insight into the topic of research but happens to be too complex or too broad to add to the body of the paper. A paper can have more than one appendix, as it is recommended to divide them according to topic.

➡️ Read more about  what is a research paper?

An appendix can take many types of forms. Here are some examples:

• Surveys. Since many researchers base their methodology on surveys, these are commonly found attached as appendices. Surveys must be included exactly as they were presented to the respondents, and exactly how they were answered so the reader can get a real picture of the findings.
• Interviews . Whether it’s a transcript or a recording, interviews are usually included as an appendix. The list of questions and the real answers must be presented for complete transparency.
• Correspondence . All types of communication with collaborators regarding the research should be included as an appendix. These can be emails, text messages, letters, transcripts of audio messages, etc.
• Research tools . Any instrument used to perform the research should be acknowledged in an appendix to give the reader insight into the process. For instance, audio recorders, cameras, special software, etc.
• Non-textual items . If the research includes too many graphs, tables, figures, illustrations, photos or charts, these should be added as an appendix.
• Statistical data . When raw data is too long, it should be attached to the research as an appendix. Even if only one part of the data was used, the complete data must be given.

➡️ Learn more about surveys, interviews, and other research methodologies .

The format of an appendix will vary based on the type of citation style you’re using, as well as the guidelines of the journal or class for which the paper is being written. Here are some general appendix formatting rules:

• Appendices should be divided by topic or by set of data.
• Appendices are included in the table of contents.

The most common heading for an appendix is Appendix A or 1, centered, in bold, followed by a title describing its content.

• An appendix should be located before or after the list of references.
• Each appendix should start on a new page.
• Each page includes a page number.
• Appendices follow a sequential order, meaning they appear in the order in which they are referred to throughout the paper.

An appendix is usually added before or after the list of references.

There is no specific space limit to an appendix, but make sure to consult the guidelines of the citation format you are using.

Yes, all appendices must be included in the table of contents.

Appendices feature different types of material, for instance interviews, research tools, surveys, raw statistical data, etc.

Welcome to the Purdue OWL

This page is brought to you by the OWL at Purdue University. When printing this page, you must include the entire legal notice.

Copyright ©1995-2018 by The Writing Lab & The OWL at Purdue and Purdue University. All rights reserved. This material may not be published, reproduced, broadcast, rewritten, or redistributed without permission. Use of this site constitutes acceptance of our terms and conditions of fair use.

APA style offers writers footnotes and appendices as spaces where additional, relevant information might be shared within a document; this resource offers a quick overview of format and content concerns for these segments of a document. Should additional clarification be necessary, it is always recommended that writers reach out to the individual overseeing their work (i.e., instructor, editor, etc.). For your convenience, a student sample paper is included below; please note the document is filled with  Lorem Ipsum  placeholder text and references to footnotes and appendices are highighlighted. Additional marginal notes also further explain specific portions of the example. 

Footnotes 

Footnotes are supplementary details printed at the bottom of the page pertaining to a paper’s content or copyright information. This supporting text can be utilized in any type of APA paper to support the body paragraphs.

Content-Based Footnotes

Utilizing footnotes to provide supplementary detail can enrich the body text and reinforce the main argument of the paper. Footnotes may also direct readers to an alternate source for more detail on a topic. Though content footnotes can be useful in providing additional context, it is detrimental to include tangential or convoluted information. Footnotes should detail a focused subject; lengthier sections of text are better suited for the body paragraphs.

Acknowledging Copyright

When citing long quotations, images, tables, data, or commercially published questionnaires in-text, it is important to credit the copyright information in a footnote. Functioning much like an in-text citation, a footnote copyright attribution provides credit to the original source and must also be included in a reference list. A copyright citation is needed for both direct reprinting as well as adaptations of content, and these may require express permission from the copyright owner.

Formatting Footnotes

Each footnote and its corresponding in-text callout should be formatted in numerical order of appearance utilizing superscript. As demonstrated in the example below, the superscripted numerals should follow all punctuation with the exception of dashes and parentheses.

For example: 

Footnote callouts should not be placed in headings and do not require a space between the callout and superscripted number. When reintroducing a footnote that has previously been called out, refrain from replicating the callout or footnote itself; rather, format such reference as “see Footnote 4”, for example. Footnotes should be placed at the bottom of the page on which the corresponding callout is referenced. Alternatively, a footnotes page could be created to follow the reference page. When formatting footnotes in the latter manner, center and bold the label “Footnotes” then record each footnote as a double-spaced and indented paragraph. Place the corresponding superscripted number in front of each footnote and separate the numeral from the following text with a single space.

Formatting Copyright Information

To provide credit for images, tables, or figures pulled from an outside source, include the accreditation statement at the end of the note for the visual. Copyright acknowledgements for long quotations or questionnaires should simply be placed in a footnote at the bottom of the page.

When formatting a copyright accreditation, utilize the following format:

• Establish if the content was reprinted or adapted by using language such as “from” for directly copied material or “adapted from” for material that has been modified
• Include the content’s title, author, year of publication, and source
• Cite the copyright holder and year of copyright or indicate that the source is public domain or licensed under Creative Commons
• If express permission was required to reprint the material, include a statement indicating that permission was acquired

Appendices 

When introducing supplementary content that may not fit within the body of a paper, an appendix can be included to help readers better understand the material without distracting from the text itself. Primarily used to introduce research materials, specific details of a study, or participant demographics, appendices are generally concise and only incorporate relevant content. Much like with footnotes, appendices may require an acknowledgement of copyright and, if data is cited, an adherence to the privacy policies that protect participant identities.

Formatting Appendices

An appendix should be created on its own individual page labelled “Appendix” and followed by a title on the next line that describes the subject of the appendix. These headings should be centered and bolded at the top of the page and written in title case. If there are multiple appendices, each should be labelled with a capital letter and referenced in-text by its specific title (for example, “see Appendix B”). All appendices should follow references, footnotes, and any tables or figures included at the end of the document.

Text Appendices 

Appendices should be formatted in traditional paragraph style and may incorporate text, figures, tables, equations, or footnotes. In an appendix, all figures, tables, and other visuals should be labelled with the letter of the corresponding appendix followed by a number indicating the order in which each appears. For example, a table labelled “Table B1” would be the first table in Appendix B. If there is only one appendix in the document, the visuals should still be labelled with the letter A and a number to differentiate them from those contained in the paper itself (for example, “Figure A3” is the third figure in the singular appendix, which is not labelled with a letter in the heading). 

Table or Figure Appendices 

When an appendix solely contains a table or figure, the title of the figure or table should be substituted with the title of the appendix. For example, if Appendix B only includes a figure, the figure should be labelled “Appendix B” rather than “Figure B1”, as it would be named if there were multiple figures included.

If an appendix does not contain text but includes numerous figures or table, the appendix should be formatted like a text appendix. The appendix would receive a name and label, and each figure or table would be given a corresponding letter and number. For example, if Appendix C contains two tables and one figure, these visuals would be labelled “Table C1”, “Table C2”, and “Figure C1” respectively.

Understanding What Is an Appendix

Many students ask, 'What is an appendix in writing?'. Essentially, an appendix is a compilation of the references cited in an academic paper, prevalent in academic journals, which can be found in any academic publication, including books. Professors frequently require their students to include an appendix in their work.

Incorporating an appendix in your written piece can aid readers in comprehending the information presented.

Meanwhile, note that an appendix comprises all the information utilized in a paper, including references and statistics from several authors and sources (the number varies according to the type of academic paper). The purpose of the appendix is to prevent vague or irrelevant information and improve the reader's understanding of the paper.

The Purpose of an Appendix

To understand what an appendix tries to accomplish and how to write an appendix example, after all, we must first answer the key question, 'What is the purpose of an appendix?'. In short, an appendix is crucial for further explaining complex information that may be difficult to fully convey within the main text of an essay. It is intended to offer readers additional information about the topic addressed in the paper.

The material presented in an appendix has the potential to bolster the argument and sway the reader's opinion. Nonetheless, you should try to incorporate supporting material and examples toward the end of the paper to avoid disrupting the flow of the main text. Furthermore, the likelihood of including an appendix increases as a paper becomes more advanced. The use of an appendix is especially prevalent in the academic writing of a research document and journal-style scientific paper, in which extra information is usually needed to support a main point of view.

How to Structure an Appendix

While there are variations between formats, each one follows a basic structure. Thus, understanding the general structure is an essential first step in learning about this topic. No matter if you're tasked with 'how to write an appendix MLA or APA style?' - remember that both adhere to this structure, despite their differences:

Every Appendix Should Contain:

• A clear title: The title of the appendix should be concise and descriptive, clearly indicating what information is contained within it. For example, 'Appendix A: Data Tables for Study Results or 'Appendix B: Images of Experimental Setup.'
• A list of contents: Including a table of contents in the appendix can be helpful for readers to navigate the information provided. For example:

Table of Contents:

A. Data Tables for Study Results

B. Images of Experimental Setup

C. Survey Questions and Responses

D. Sample Interview Transcripts

• Page numbers: The appendix should be a separate page, independently numbered from the main body of the paper, and specified uniformly (e.g., 'Appendix A,' 'Appendix B,' etc.). For example:

Page 1 of 5

• Relevant information: The appendix should contain all the relevant information supporting the main arguments of the document, including tables of data, raw statistical data, charts, or other documents. For example:

Figure 1: Experimental Results

[insert graph or chart here]

• Proper formatting: The appendix should be formatted in accordance with the specific requirements of the chosen citation style (e.g., APA, MLA, Chicago). For example:

Appendix B: Survey Questions and Responses

[insert survey questions and responses here, formatted following APA style guidelines]

• Clear labeling: Each element should have a clear appendix label so readers can easily understand its relevance to the paper. For example:

Table 1: Demographic Characteristics of Survey Respondents

• Concise explanation: It is important to provide short detailed descriptions of each element in the Appendix so that readers can understand its importance. For example:

Appendix C: Sample Interview Transcripts

Transcripts of the three interviews with the study participants shall be included for reference. These interviews provide further insights into the experiences of participants and their views on the subject addressed in this document.

While composing your work, you may stumble upon a question on how to write an appendix.

An appendix is a supplemental section of a research paper that provides additional information, data, or materials to support the main content. The appendix is usually placed at the end of the document and is numbered with letters or numbers, such as "Appendix A," "Appendix B," etc. The purpose of an appendix is to provide readers with supplementary details that are not included in the main text but are relevant to the topic.

Once you decide on writing appendices, you should collect additional information and format your text as required. Here, we will talk about how you can work with appendices. We will also show some nuances of their preparation process using a real example. Is the deadline around the corner? Consider using professional research paper help from expert scholars.

What Is an Appendix: Definition

Experienced researchers know what an appendix in a paper is. But aspiring authors often have problems with this section of the work. First of all, you should understand that appendices are an additional section of a dissertation or any other scientific paper that includes additional information. Main points are not placed in an appendix meanwhile at the end of your work it can expand on some context or clarify author’s position on a particular issue. Also, an appendix is ​​often placed after the citation page of a work. It is indicated with the help of references in a main text.

What Is the Purpose of an Appendix

Quite often, authors don’t understand the purpose of an appendix. This usually looks like a table and is not included in a main text. Remember that content of your dissertation should be concise and clear. It is also undesirable if you deviate from your theme so as not to confuse readers. Therefore, you can provide a reference, which will lead a reader to an appendix of a thesis. Typically, the purpose of an appendix is to extra information that is usually not included in the text's body. It expresses author's point of view, and provides additional information. It may not address the immediate topic of your dissertation or expand on current research. As a reminder, your work should be clear even without studying an appendix. So make sure you don't put important details there.

What Can You Include in an Appendix

An appendix in a paper is a supplement to a main text, not a replacement. You can put different elements there. It is better if you separate appendices, highlighting one element in each of them. Don’t forget about separate references in your text. Otherwise it will be difficult for a reader to understand your information better. Thus, the following information can be added:

• diagrams with illustrative figures;
• abbreviations ;
• interviews;
• statistics, and much more.

There are no restrictions on content added to your dissertation's appendices. Theoretically, you can attach absolutely any information that is relevant to your topic. Thus, possibilities for evidence base are almost unlimited. All you need to do is add tables or any other information.

How to Write an Appendix: Full Guide

If you already have experience working on dissertations and other scientific texts, you will not wonder how to make an appendix. However, it is still important that you get some advice on how to properly structure an appendices section. This will help add information that may be redundant in the main part of your paper. We offer 4 simple steps to create an informative and readable appendix block.

Step 1. Make an Appendix: Include Your Data

When creating an appendix, include extra data in their raw form. That is, you might not have used some details in your main paper. But you want a reader to know more information. For example, it can be calculations, some results of which are mentioned in your main text. Or maybe, you can add some statistics that clearly demonstrate your research paper conclusion . You can also include facts from other scientific sources that support your position. One thing is important — information should complement your text but not contradict it.

Step 2. Include Visual Supporting Documents in an Appendix 

When you are writing an appendix, you can’t avoid visual additions that clearly demonstrate an information and save an author from lengthy descriptions in the text. Should you need to support your conclusions drawn in the scientific text, these can be used:

Don’t forget: you should quote and indicate the authorship of graphics used in your work. If you took it from any third-party sources, of course. Thus, a reader will be able to find additional data that explains the content of your text. It is good if you personally put results of your research in a graphic form. To do this, you can use Office programs, graphic editors and other programs available to PC users.

Step 3. Describe the Instruments of Your Research in Your Appendices

It is good if your appendix in the research paper has a section for indicating tools that were used during the preparation of your dissertation writing . This way, your reader will understand how you collected information and do it themselves. For example, it could be a dictaphone or tape recorder on which an interview with your expert was recorded. Or you might have used a video camera for recording facts and interviews. In such case, it is advisable to indicate these instruments in your appendix. Specialized equipment for measuring, calculating and making graphics should also be added at the beginning of the appendix. This way, you will demonstrate your skills and knowledge. Research units don’t require extra tools, so make sure they are listed. You can do it even in a short format.

Step 4. Include an Interview and Transcripts in an Appendix

When conducting interviews and surveys for collecting information, make an appendix with photocopies of handwritten materials or electronic copies of digital surveys. Their order is not important. The main thing is that your research text contains references. This will allow you to quickly study the sources. You should not only show that the source contains important data but also explain it. So, even additional content, including questions and answers, needs to be listed. But if you originally had a readable format, you don’t need to do this. In addition to interviews, also add screenshots or photos of correspondences used for surveys. For example, you can refer to a significant researcher with whom you exchanged letters. Or maybe you studied subject, together with this researcher, and they gave some comments on a particular issue. Do not know how to write a discussion section of a research paper ? Do not worry, we have the whole article dedicated to this topic.

Formatting an Appendix: Main Rules

Formatting of appendices is required in any case. First of all, provide correct citations. APA, MLA, and Chicago are the most commonly used standards. Although, you should clarify what formatting requirements your institution has. Correct formatting includes:

• Appendix title. Write it at the top of the content page, indicate its title, using letters or numbers for ordering.
• Sorted by mention. Don’t add appendices randomly, it is better to do it in chronological order. That is, as information from it is given in main text.
• Location after bibliography. This is a general requirement that cannot always be met. For example, if your professor wants the appendices to be put before the bibliography, this will have to be done.
• Page numbers. All dissertation pages should be numbered, even if they are blank. This will make the appendix block the part of main text.

Also, review your appendix before approval. Make sure that its content is clear, error-free, and correctly quoted.

Appendix Example

To do the job successfully, it is recommended to have an example of an appendix at hand. Without it, there are usually problems with a choice of font and mentions that appear in main text. We will show you what the appendix itself looks like at the end of the dissertation using a short interview as an example.

How to Make an Appendix: Final Thoughts

Thus, we talked about how to write an appendix. It allows you to include additional details, while avoiding writing them in the body of your text. To do this, one can use graphics, transcriptions of conversations, tables and statistics — anything that complements your research. Be sure to clarify formatting requirements of your university. Arrange appendices in an order in which they appear in your text. Try to use your own materials and not take other people's work. In case of unique findings, they can be used in your work.

Thesis and Dissertation Appendicies – What to Include

• By DiscoverPhDs
• August 12, 2020

An appendix is a section at the end of a dissertation that contains supplementary information. An appendix may contain figures, tables, raw data, and other additional information that supports the arguments of your dissertation but do not belong in the main body.

It can be either a long appendix or split into several smaller appendices. Each appendix should have its own title and identification letters, and the numbering for any tables or figures in them should be reset at the beginning of each new appendix.

Purpose of an Appendix

When writing the main body of your dissertation, it is important to keep it short and concise in order to convey your arguments effectively.

Given the amount of research you would have done, you will probably have a lot of additional information that you would like to share with your audience.

This is where appendices come in. Any information that doesn’t support your main arguments or isn’t directly relevant to the topic of your dissertation should be placed in an appendix.

This will help you organise your paper, as only information that adds weight to your arguments will be included; it will also help improve your flow by minimising unnecessary interruptions.

Note, however, that your main body must be detailed enough that it can be understood without your appendices. If a reader has to flip between pages to make sense of what they are reading, they are unlikely to understand it.

For this reason, appendices should only be used for supporting background material and not for any content that doesn’t fit into your word count, such as the second half of your literature review .

What to Include in a Dissertation Appendix

A dissertation appendix can be used for the following supplementary information:

Research Results

There are various ways in which research results can be presented, such as in tables or diagrams.

Although all of your results will be useful to some extent, you won’t be able to include them all in the main body of your dissertation. Consequently, only those that are crucial to answering your research question should be included.

Your other less significant findings should be placed in your appendix, including raw data, proof of control measures, and other supplemental material.

Details of Questionnaires and Interviews

You can choose to include the details of any surveys and interviews you have conducted. This can include:

• An interview transcript,
• A copy of any survey questions,
• Questionnaire results.

Although the results of your surveys, questionnaires or interviews should be presented and discussed in your main text, it is useful to include their full form in the appendix of a dissertation to give credibility to your study.

Tables, Figures and Illustrations

If your dissertation contains a large number of tables, figures and illustrative material, it may be helpful to insert the less important ones in your appendix. For example, if you have four related datasets, you could present all the data and trend lines (made identifiable by different colours) on a single chart with a further breakdown for each dataset in your appendix.

Letters and Correspondence

If you have letters or correspondence, either between yourself and other researchers or places where you sought permission to reuse copyrighted material, they should be included here. This will help ensure that your dissertation doesn’t become suspected of plagiarism.

List of Abbreviations

Most researchers will provide a list of abbreviations at the beginning of their dissertation, but if not, it would be wise to add them as an appendix.

This is because not all of your readers will have the same background as you and therefore may have difficulty understanding the abbreviations and technical terms you use.

Note: Some researchers refer to this as a ‘glossary’, especially if it is provided as an appendix section. For all intended purposes, this is the same as a list of abbreviations.

Finding a PhD has never been this easy – search for a PhD by keyword, location or academic area of interest.

How to Format a Dissertation Appendix

In regards to format, you can include one lengthy appendix or structure it into several smaller appendices.

Although the choice is yours, it is usually better to opt for several different appendices as it allows you to organise your supplementary information into different categories based on what they are.

The following guidelines should be observed when preparing your dissertation appendices section:

• Each appendix should start on a new page and be given a unique title and identifying letter, such as “Appendix A – Raw Data”. This allows you to more easily refer to appendix headings in the text of your main body should you need to.
• Each appendix should have its own page numbering system, comprising the appendix identification letter and the corresponding page number. The appendix identification letter should be reset for each appendix, but the page number should remain continuous. For example, if ‘Appendix A’ has three pages and ‘Appendix B’ two pages, the page numbers should be A-1, A-2, A-3, B-4, B-5.
• The numbering of tables and figures should be reset at the beginning of each new appendix. For example, if ‘Appendix A’ contains two tables and ‘Appendix B’ one table, the table number within Appendix B should be ‘Table 1’ and not ‘Table 3’.
• If you have multiple appendices instead of a single longer one, insert a ‘List of Appendices’ in the same way as your contents page.
• Use the same formatting (font size, font type, spacing, margins, etc.) as the rest of your report.

Example of Appendices

Below is an example of what a thesis or dissertation appendix could look like.

Referring to an Appendix In-Text

You must refer to each appendix in the main body of your dissertation at least once to justify its inclusion; otherwise, the question arises as to whether they are really needed.

You can refer to an appendix in one of three ways:

1. Refer to a specific figure or table within a sentence, for example: “As shown in Table 2 of Appendix A, there is little correlation between X and Y”.

2. Refer to a specific figure or table in parentheses, for example: “The results (refer to Table 2 of Appendix A) show that there is little correlation between X and Y”.

3. Refer to an entire appendix, for example: “The output data can be found in Appendix A”.

Appendices vs Appendixes

Both terms are correct, so it is up to you which one you prefer. However, it is worth noting that ‘appendices’ are used more frequently in the science and research community, so we recommend using the former in academic writing if you have no preferences.

Where Does an Appendix Go?

For a dissertation, your appendices should be inserted after your reference list.

Some people like to put their appendices in a standalone document to separate it from the rest of their report, but we only recommend this at the request of your dissertation supervisor, as this isn’t common practice.

Note : Your university may have its own requirements or formatting suggestions for writing your dissertation or thesis appendix. As such, make sure you check with your supervisor or department before you work on your appendices. This will especially be the case for any students working on a thesis.

• Appendix B: Mode experiment

The data in this report is drawn from a national cross-sectional, address-based sampling (ABS) survey conducted for Pew Research Center by Westat. This survey was fielded Nov. 19, 2019, through June 3, 2020.  Self-administered screening interviews were conducted with a total of 68,398 U.S. adults either online or by mail, resulting in 4,718 interviews with Jewish adults who are the primary subject of this report. This included 3,836 who are Jewish by religion and 882 who consider themselves Jewish but not by religion. Another 1,163 interviews were conducted with adults who are not Jewish (according to the criteria used in this report) but have a Jewish background or other Jewish affinity. After accounting for the complex sample design and loss of precision due to weighting, the margin of sampling error for the 4,718 net Jewish respondents is plus or minus 3.0 percentage points at the 95% level of confidence.

The survey was administered in two stages. In the first stage, a short screening survey was administered to a national sample of U.S. adults to collect basic demographics and determine a respondent’s eligibility for the extended survey of Jewish Americans. Screener respondents were considered eligible for the extended survey if they met any of the following three conditions:

• They identified as Jewish when asked about their religious identity.
• They did not identify as Jewish by religion but said that they consider themselves to be Jewish in any other way, such as ethnically, culturally or because of their family’s background.
• They did not identify as Jewish at all but indicated that they were raised in the Jewish tradition or had a Jewish parent.

The screener was also used to identify eligible respondents for a separate study focused on the religious experiences of Black Americans . 49 This was done primarily for efficiency, since both populations make up a relatively small share of the total U.S. adult population and obtaining a sufficient sample size for either group requires screening a much larger number of adults. For the small number of respondents who were eligible for both surveys, a random 80% were assigned to the extended Jewish American survey and the remaining 20% were assigned to the survey of Black Americans. The weights for these respondents were adjusted upward proportionately to account for this subsampling and ensure that the population of Black Jews was not underrepresented in the samples of either study. 50

Throughout this appendix, the terms “extended survey” and “extended questionnaire” refer to the extended survey of Jewish Americans that is the focus of this report, and “eligible adults” and “eligible respondents” refer to those individuals who met its eligibility criteria, unless otherwise noted.

Sample design

The survey had a complex sample design constructed to maximize efficiency in reaching Jewish adults while also supporting reliable, national estimates for this population. The study used a stratified, systematic sample of U.S. residential mailing addresses. The ABS frame originates from the U.S. Postal Service’s Computerized Delivery Sequence File (CDSF) updated every month. That frame is maintained by Marketing Systems Group (MSG). MSG geocodes their entire ABS frame, so block, block group and census tract characteristics from the decennial census and the American Community Survey (ACS) can be appended to addresses and used for sampling and data collection purposes. The stratification of the sampling frame and the assignment of differential sampling rates to the strata were a critical design component because of the rareness of the eligible populations. Because the Jewish population was much rarer than the Black population, the stratification mainly identified areas with high concentrations of Jewish adults.

The first source for identifying areas with a higher density of Jewish adults was a file made available to Pew Research Center by the American Jewish Population Project (AJPP) at Brandeis University. The U.S. government does not collect data that classifies people by religion, so the AJPP data is the best source available. The AJPP provided pre-release data for this purpose (Pre-Release Estimates, July 2019). The available tables were at the county or county-group level and had estimates of both the total number of adults and the proportion of adults who identified themselves as Jewish by religion for each county group. Based on the distribution of the proportion of Jewish adults by religion in the county groups, Westat partitioned the county groups into two classes based on estimated Jewish density (high and low).

The next step was to stratify the areas within the county groups in the high-density class. Pew Research Center provided data from surveys conducted in 2013 or later that contained the respondents’ religious affiliation, ZIP code and sampling weights. Westat used that data to estimate the proportion of Jewish adults at the ZIP code level. Unfortunately, the Census Bureau does not report population counts at the ZIP code level. Instead, the Census Bureau reports counts at the ZIP Code Tabulation Areas (ZCTAs) level. Westat implemented a crosswalk between ZCTA and ZIP codes and then produced estimates of the proportion of Jewish adults at the ZCTA level within county groups for those county groups in the high-density class.

Since the sample sizes in the ZCTAs from the Pew Research Center surveys were often very small, zero or missing, the estimates of the percentage of Jewish adults in the ZCTA were not precise. As a result, each county group in the high-density class was partitioned into just two pieces within the county group. The first part included all ZCTAs with the highest estimated percentage of Jews by religion in the county group, and the other had the remainder of ZCTAs. Westat assigned all high-density ZCTAs to stratum 1. The lower-density ZCTAs were placed in stratum 2. The county groups or individual counties in the low-density class were placed in stratum 3.

The last step in the stratification divided each stratum into three substrata. For the higher-density strata (1 and 2), the substratum boundaries were determined using the square root of the ZCTA-level estimate of the number of Jewish adults. In the lowest-density stratum (3), the substratum boundaries were based on the estimated number of Jewish adults in the county group.

Westat divided the sample of drawn addresses into two replicate subsamples. At the beginning of data collection, Westat only mailed to the first replicate of addresses. About two months later, Westat began mailing the second replicate of addresses. This approach allowed researchers to evaluate the performance of the data collection protocol and apply adjustments before the second replicate was fielded. From the first replicate, it was clear that the response rate to the screening interview was lower than projected. To address the shortfall, Westat supplemented the sample with additional addresses and made small changes to the study materials.

One of the changes implemented between replicates was to the procedure used to randomly select one adult from each sample household. In the first replicate, each sampled address was randomly assigned to one of four groups, referred to as YM, OM, YF or OF. In group YM, the youngest male adult is sampled (if there are no males, the youngest female is sampled). Group OM samples the oldest male (or oldest female if no males present). YF and OF are the analogous groups for sampling women by age. After the first replicate fell short of yield projections, a simpler selection procedure was used; the adult in the household with the next birthday was instructed to complete the survey. The next-birthday method was also used for the last two screener recruitment mailings for the first replicate.

Data collection

To maximize response, the study used a sequential mixed-mode protocol in which sampled households were first directed to respond online and later mailed a paper version of the questionnaire if they did not respond online.

The first mailing was a letter introducing the study and providing the information necessary (URL and unique PIN) for online response. A pre-incentive of $2 was included. This and remaining screener recruitment letters focused on the screener survey, without mentioning the possibility of eligibility for longer surveys and associated promised incentive, since most people would only be asked to complete the short screening survey.

Next, Westat sent a postcard reminder, followed by a reminder letter to nonrespondents. Westat later sent nonrespondents a paper version screening survey, which was a four-page booklet (one folded 11×17 paper) and a postage-paid return envelope in addition to the cover letter. If no response was obtained from those four mailings, no further contact was made.

Eligible adults who completed the screening interview on the web were immediately asked to continue with the extended questionnaire. If an eligible adult completed the screener online but did not complete the extended interview, Westat sent them a reminder letter. This was performed on a rolling basis when it had been at least one week since the web breakoff. Names were not collected until the end of the web survey, so these letters were addressed to “Recent Participant,” but the content of the letter referenced the reported age and sex of the participant when available, so that the same participant would continue the survey.

If an eligible respondent completed a paper screener, Westat mailed them the appropriate extended survey and a postage-paid return envelope. This was sent weekly as completed paper screeners arrived. The paper screeners asked for a “first name or initials in case we have any questions about your survey,” and Westat addressed the extended mailings using this information. The content of the letter also referenced the reported age and sex of the participant when available. Westat followed these paper mailings with a reminder postcard. Later, Westat sent a final paper version via FedEx to eligible adults who had not completed the extended interview online or by paper.

In addition to the $2 prepaid incentive that was included in the initial mailing sent to all sampled addresses, screener respondents who were eligible for the extended questionnaire were offered an additional promised incentive to be paid upon completion. Its value differed depending on how and when the respondent completed the screener. For the first sample replicate, respondents who completed the screener online were offered either $10 or $20 at random as part of an experiment to determine whether the response rate was sensitive to the promised value. The experiment found that the higher incentive did not result in significantly greater participation. Consequently, all eligible respondents who completed the screener online after the start of the second sample replicate were offered $10. Respondents who were sent a paper version of the extended questionnaire, either because they completed the screener by paper or because they never finished the extended questionnaire online, were offered $50.

The self-administered mail and web screening surveys were developed in English and translated into Spanish and Russian. For web, the landing page was in English, with language selection buttons available on that page to anyone, and throughout the survey, to change to Spanish or Russian. The paper screener was also formatted in English, Spanish and Russian. Recipients thought to be more likely to make use of Spanish or Russian options, based on supplemental information on the sampling frame or their address location, were sent the Spanish or Russian paper screener in addition to the English one.

The Jewish extended survey was available in English and Russian. For web, respondents continued in their selected language from the screener. Those receiving a paper extended instrument were sent the language corresponding to the language in which the screener was completed. In the rare occurrence that someone selected for the Jewish extended survey completed the screener in Spanish, the extended instrument was provided in English.

Weighting and variance estimation

Household-level weighting.

The first step in weighting was the creation of a base weight equal to the inverse of each household’s probability of selection as determined by the stratum from which it was sampled. The base weight for mailing address k is called BW k , defined as the inverse of its probability of selection.

Each sampled mailing address was assigned to one of four categories according to its final screener disposition. The categories were 1) eligible household with one or more adults with a completed screener interview, 2) eligible household with one or more adults without a completed screener interview, 3) ineligible (i.e., not a household, which were primarily postmaster returns), and 4) household with unknown eligibility (addresses that were not identified as undeliverable by the post office but from which no survey response was received).

The first step in adjusting the base weight accounted for eligible sampled addresses among those with unknown eligibility (category 4). Previous ABS studies have found that about 13% of all addresses in the ABS frame were either vacant or are not home to anyone in the civilian, non-institutionalized population. For this survey, we assumed that 87% of all sampled addresses were eligible households. Thus, we adjusted the base weight in category 4, so the weights represented the portion of cases assumed to be eligible. The value of the adjustment factor was computed so that the sum of the base weights in categories 1 and 2 (eligible respondents and nonrespondents) and the adjusted cases in category 4 represented 87% of the frame total. The category 3 ineligible addresses are then given a weight of zero. We referred to this adjusted base weight as BW1 k  = BW k   x p  where  p is the assumed eligibility factor applied to addresses in category 4. The weights in categories 1 and 2 were not adjusted; however, the sum of weights in categories 1, 2, and adjusted weights in 4 summed to the total for all eligible nonrespondents.

The next step allocated the weights from assumed eligible cases in category 4 to the weights in categories 1 (screener interview eligible respondents) and 2 (screener interview eligible nonrespondents). The adjustment was done separately by weighting classes derived from auxiliary data available at the address level. A separate weighting class was created to target the adjustment for the addresses in three counties identified as having a large Orthodox Jewish density (Kings and Rockland counties in New York and Ocean County in New Jersey). The remaining classes were defined by the cross-classification of sampling strata, the Black sampling sub-strata, and the census region definition. These variables defined an initial set of 64 classes. Those classes with fewer than 150 sampled addresses were collapsed. There were 60 classes after collapsing. The nonresponse adjustment factor  FW1 c  for this adjustment was the ratio of thee sum of the  BW1 weights divided by thee sum of the  BW1 of the respondents in the same class  c as FBW1 c = Σ ch BW1 hk /∑ resp∈h BW1 hk . The adjusted weight is BW2 hk = FBW1 c x BW1 hk .

The next step was adjusting for nonresponse for households without a completed screener interview. This adjustment allocated the weights of nonrespondents (category 2) to those of respondents (category 1). The adjustment was done separately by the same weighting classes used for the previous adjustment. The nonresponse adjustment factor  FBW2 c  for this adjustment was the ratio of the sum of the  BW2  weights divided by the sum of the  BW2  of the respondents in the same class  c as FBW2 c = Σ ch BW2 hk /∑ resp∈h BW2 hk . The adjusted weight is BW3 hk = FBW2 c x BW2 hk .

Weighting screened adults

To create an adult-level weight for all of the adults who completed the screener interview, the household weights were adjusted to account for randomly sampling one adult in each household. The initial adult level weight is AW1 k = BW3 k x a k is the number of adults in the household capped at 3 to avoid highly influential weights. 51 Thee adult weights ( AW1 k ) were then raked to match a set of estimated population benchmarks. The adult raked weight was ARKW ck = AW1 k x RK c , where RK c was the common adjustment for thee set of respondent characteristics c .

The raking dimensions for the adult weights were:

• Eligibility type by sex
• Eligibility type by age
• Eligibility type by education
• Orthodox stratum by sex 52
• Age by education
• Single/multiple-adult household by presence of children in household
• Race and Hispanic ethnicity
• Census region
• Sampling stratum

Because eligibility type is not a variable for which external benchmarks exist, the weighting parameters instead use model-based estimates for the number of adults in each of the groups that determined eligibility for the extended survey: 1) adults who consider themselves Jewish by religion, 2) adults who are not Jewish by religion but consider themselves Jewish for other reasons, 3) adults who do not consider themselves Jewish but were raised Jewish or had a Jewish parent, and 4) ineligible adults.

Modeling made it possible to estimate the size and demographic composition of the eligible adult population while adjusting for both the complex sample design and a larger number of variables and their interactions than would otherwise be possible. This was done to correct for subtle nonresponse patterns that, while negligible in their impact on national estimates for the full U.S. adult population, had an outsize effect on the size and composition of the responding Jewish sample. The process used to produce the modeled estimates is detailed in the next section.

Initial weighting of extended survey respondents

The eligible adults who completed the extended interview were assigned an initial Jewish interview weight equal to ARKW k . Because of the high skewness of the distribution of the weights for the cases sampled for the Jewish survey, the weights were trimmed at the 95th percentile and then adjusted to account for the subsampling of the respondents who were eligible for both the Jewish American and Black American surveys.

This weight was then raked to align with a set of parameters that were also based on modeled estimates for the demographic composition for the Jewish categories discussed in this report: 1) Jews by religion, 2) Jews of no religion, and 3) adults with a Jewish background or affinity. The model also distinguished between Orthodox and non-Orthodox Jews by religion. The specific raking dimensions for the extended weight were:

• Jewish category by Orthodox/non-Orthodox
• Jewish category by age
• Jewish category by education
• Orthodox stratum by sex

To reduce the variability of the weights while preserving the relative size of the Jewish population segments, the raked weights were then trimmed separately within each of the detailed Jewish categories at the 99.3rd percentile. This initial raked weight for the Jewish extended respondents is called EXTWT k .

Household roster weights

Part of the extended interview involved rostering all of the adults and children in each respondent’s household. To facilitate the analysis of the roster data, a household dataset was created that contained one row for every adult and child in each responding household. All persons in a household were given a household weight ( EXTWTHH k ) equal to the extended respondent’s initial weight ( EXTWT k ) divided by the number of eligible adults in the household. This accounts for the fact that household members would have been rostered if any eligible adult had been sampled other than the respondent.

Roster adjustment to extended respondent weights

A final adjustment was made to the weights for the extended interview respondents to correct an imbalance in the distribution of men and women in Orthodox households. Although Orthodox respondents were disproportionately male using the extended respondent weight ( EXTWT k ), the share of eligible men and women in Orthodox households was evenly balanced using the household weight ( EXTWTHH k ). Such an outcome would be highly unlikely if the responding adult were selected at random, and suggests a tendency in Orthodox households to choose a male respondent instead of the adult with the next birthday.

To correct this imbalance, the extended respondent weight was raked one more time so that the distributions of sex for Orthodox and non-Orthodox respondents matched the distribution all eligible rostered adults using the EXTWTHH k . The rostered distribution for Jewish category was also included as a raking dimension for this step to ensure consistency between the household and respondent weights. This final weight, EXTWTFIN k , is used for the bulk of the analysis in this report.

Variance estimation

Because the modeled estimates used in the weighting are themselves subject to sampling error, variance estimation and tests of statistical significance were performed using the grouped jackknife estimator ( JK 2). One hundred sets of replicates were created by deleting a group of cases within each stratum from each replicate and doubling the weights for a corresponding set of cases in the same stratum. The entire weighting and modeling process was performed on the full sample and then separately repeated for each replicate. The result is a total of 101 separate weights for each respondent that have incorporated the variability from both the complex sample design, modeling and estimation of weighting parameters. 53

Model-based population estimates

As previously mentioned, the weights for the survey of Jewish Americans rely on model-based estimates for the size and demographic composition of the eligible adult population. Whereas design-based estimation depends on knowing each individual’s probability of inclusion in the sample, model-based estimation involves fitting a regression model to the survey data predicting an outcome variable of interest as a function of a set of covariates whose distributions are known for both the individuals in the sample and for the larger target population. That model is then used to obtain predicted values of the outcome for all of the non-sampled individuals in the population. 54

Modeling screener eligibility

The first stage in modeling the size and composition of the eligible adult population was to fit a model predicting whether an adult respondent to the screener was eligible for the extended survey because they either 1) identified their religion as Jewish, 2) did not identify as Jewish by religion but indicated that they consider themselves to be Jewish for reasons aside from religion, or 3) did not consider themselves Jewish but had a Jewish parent or Jewish background; or 4) whether they were not eligible. This step was intended to correct for screener nonresponse that may have been associated with eligibility for the extended interview.

To ensure that the modeling accounted for the informative sample design, sampling stratum and the number of adults in the household were included in the model as predictors. Additional demographic predictors included age, sex, race and Hispanic ethnicity, and an indicator for the presence of children in the household. Geographic predictors included a flag identifying respondents residing in one of the three high-density Orthodox counties, a measure of urbanicity based on the National Center for Health Statistics’ urban-rural county classifications , census region, and a geographic grouping variable. The geographic group was defined as county for those counties that had at least 300 respondents to the screener. Counties with fewer than 300 respondents were grouped according to state. Any remaining groups that still did not have 300 respondents were combined according to census division. This resulted in a total of 79 groups, of which only the Pacific remainder (n=236) and East-South-Central remainder (n=163) had fewer than 300 respondents.

The model was fit using multinomial logistic ridge regression as implemented in the glmnet package for the R statistical computing platform . 55  Ridge regression is a form of penalized regression that allows for the inclusion of a large number of predictor variables and interactions by shrinking the coefficients for irrelevant variables to be very close to zero. It performs particularly well when many of the predictors are correlated with each other, as was the case here.

The model included main effects for all of the predictor variables listed above. Interaction terms were selected using repeated 10-fold cross-validation. In 10-fold cross-validation, the full sample is randomly divided into 10 equally sized groups. Sequentially, each group is removed from the full sample and a set of candidate models is fit to the remaining 90% of the data. The models’ out-of-sample predictive accuracy is then measured on the 10% that was withheld. The model specification with the best average performance across all 10 groups is then chosen as the final model.

To select the final model specification, every possible two-way interaction between predictors was first ranked according to the cross-validated performance of a model containing only main effects and the single interaction. Then, interaction terms were cumulatively added to a base model one at a time. Interaction terms were retained in the cumulative model if their inclusion led to cross-validated performance that was as good as or better than the cumulative model, otherwise they were dropped. Interaction terms that included geographic group were added to the cumulative model last due to the very large number of additional coefficients that they entail. The specification that had the best performance in cross-validation was then fit to the full dataset with all 68,398 screener respondents to create the final model.

Modeling Jewish category

The second stage of modeling was intended to correct for nonresponse to the extended interview among eligible adult respondents. In particular, the goal was to correct nonresponse that was differentially associated with important segments of the Jewish population. For this stage, a model predicting whether someone was 1) Jewish by religion and Orthodox, 2) Jewish by religion but not Orthodox, 3) Jewish but not by religion, or 4) of Jewish background or Jewish affinity was fit to the data for the 5,881 eligible adults who completed the extended Jewish survey.

For predictors, this model added eligibility type to the list of variables used in the first stage. The model included main effects for all of the predictor variables with interactions selected using the same procedure as the first-stage model.

Creating a population frame

Using the models to generate population estimates requires knowing the complete distribution of all of the predictor variables that were used in the model fitting. The primary source for the distribution of the predictor variables was the 2018 ACS 5-year Public Use Microdata Sample (PUMS). The smallest geographic units on the PUMS are Public Use Microdata Areas (PUMAs), which do not directly correspond to the geographic units used in the modeling. Specifically, counties are needed to create variables for high-density Orthodox counties, urbanicity and geographic group. Additionally, the strata used in the sample design require the cross-classification of both county and ZIP code.

To solve this problem, the PUMS was merged with a crosswalk identifying the proportion of each PUMA’s population that lives in any of the counties with which it intersects. The weights for each person in the dataset were then distributed across counties proportionate to their share of the PUMA’s population. Then, a similar crosswalk was used to further allocate each person’s weights proportionately across the ZIP Code Tabulation Areas (ZCTAs) that intersect with their county. Both crosswalks were obtained from the Missouri Census Data Center’s Geocorr 2014 .

Appending county and ZCTA to the PUMS made it possible to create all of the geographic variables that were used in the modeling. A variable identifying the groups of ZCTAs that crossed stratum boundaries was also created. Each record in this augmented PUMS dataset was grouped into cells defined by the cross-classification of housing type, ZCTA groups and all of the predictor variables used in the modeling and their weights were summed to create a dataset with one row for every unique combination of predictor variables and a weight identifying the total number of people in that cell.

Because allocating weights proportionately across counties and ZCTAs is only a rough approximation, these weights were then raked so that the distributions for age, sex, race and Hispanic ethnicity within counties aligned with 2018 estimates from the Census Bureau’s Population Estimates Program (PEP). The raking also aligned the distribution of age by education separately within counties and ZCTA groups, respectively, to match estimates from the 2018 5-Year ACS tables. Finally, the dataset was filtered to only the records for the non-institutionalized adult and the calibrated weights were scaled so that their sum matched the 2018 ACS 5-year PUMS.

Next, the first-stage model was applied to this population frame to predict the proportion of adults in each cell who belong to each eligibility category. These proportions were multiplied by the total number of adults to create new cells for each of the eligibility categories. The second-stage model was then used to further subdivide the cells for eligible adults according to Jewish category.

The end result is a dataset with one row for every unique combination of the predictor variables, eligibility type and detailed Jewish category with a weight reflecting the estimated number of adults in each. This final dataset was then used to compute the estimated population benchmarks that were used in the weighting discussed above.

Response rates

Westat assigned all sampled cases a result code for their participation in the screener, and then they assigned a result for the extended questionnaire for those who were eligible for the survey of Jewish Americans. Two of the dispositions warrant some discussion. One is the category “4.313 No such address.” This category is for addresses that were returned by the U.S. Postal Service as not being deliverable. This status indicates the address, which was on the USPS Delivery Sequence File at the time of sampling, currently is not occupied or no longer exists. The second category is “4.90 Other.” This category contains 1,231 addresses that were never mailed because they had a drop count of greater than four. Drop points are addresses with multiple households that share the same address. The information available in the ABS frame on drop points is limited to the number of drop points at the address, without information on the type of households at the drop point, or how they should be labeled for mailing purposes. In this survey, all drop points were eligible for sampling, but only those with drop point counts of four or fewer were mailed. Westat treated drop point counts of five or more as out of scope, and no mailing was done for those addresses.

Westat used the disposition results to compute response rates consistent with AAPOR definitions. The response rates are weighted to account for the differential sampling in this survey. The weight is the inverse of the probability of selecting the address. 56 The AAPOR RR3 response rate to the screening interview was 20.1%. 57  The RR3 response rate to the extended Jewish American interview, 82.4%, is the number of eligible adults completing the questionnaire over the total sampled for that extended questionnaire. The overall response rate is the product of the screener response rate and the conditional response rate for the extended questionnaire. The overall response rate for the Jewish American sample in the Pew Research Center ABS survey was 16.6% (20.1% x 82.4%).

Many individuals contributed to this study’s data collection and methodology. In particular, Pew Research Center is grateful to Hanna Popick, Eric Jodts, Mike Brick and Ismael Flores Cervantes from Westat and to Elizabeth Tighe from the American Jewish Population Project for their many contributions to this project.

• Screened adults were considered eligible for the Black American survey if they identified as Black or Afro-Latino. ↩
• In other words, the fact that not everyone who is both Black and Jewish was asked to complete the survey of U.S. Jews does not mean that the study undercounts Black Jews. The 80% of Black Jews randomly assigned to receive the Jewish survey had their statistical weights adjusted upward to account for the fact that 20% of Black Jews were assigned to the other study, ensuring that Black Jews are represented in their proper proportion in all estimates produced by the Jewish survey. Put another way, in the final weighted estimates, the 80% of Black Jews who received the Jewish survey effectively “stand in” for the 20% of Black Jews randomly assigned to receive the other survey. Similarly, the 20% of Black Jews who received the survey of Black Americans had their statistical weights adjusted upward in that study so Jews are represented in their proper proportion in all estimates produced by Pew Research Center’s survey of religion among Black Americans. ↩

An appendix contains supplementary material that is not an essential part of the text itself but which may be helpful in providing a more comprehensive understanding of the research problem or it is information that is too cumbersome to be included in the body of the paper. A separate appendix should be used for each distinct topic or set of data and always have a title descriptive of its contents.

Importance of...

Appendices are always supplementary to the research paper. As such, your study must be able to stand alone without the appendices, and the paper must contain all information including tables, diagrams, and results necessary to understand the research problem. The key point to remember when including an appendix is that the information is non-essential; if it were removed, the reader would still be able to  comprehend the significance, validity , and implications of your research.

It is appropriate to include appendices for the following reasons:

• Including this material in the body of the paper that would render it poorly structured or interrupt the narrative flow;
• Information is too lengthy and detailed to be easily summarized in the body of the paper;
• Inclusion of helpful, supporting, or useful material would otherwise distract the reader from the main content of the paper;
• Provides relevant information or data that is more easily understood or analyzed in a self-contained section of the paper;
• Can be used when there are constraints placed on the length of your paper; and,
• Provides a place to further demonstrate your understanding of the research problem by giving additional details about a new or innovative method, technical details, or design protocols.

Structure and Writing Style

I.  General Points to Consider

When considering whether to include content in an appendix, keep in mind the following:

• It is usually good practice to include your raw data in an appendix, laying it out in a clear format so the reader can re-check your results. Another option if you have a large amount of raw data is to consider placing it online and note that this is the appendix to your research paper.
• Any tables and figures included in the appendix should be numbered as a separate sequence from the main paper . Remember that appendices contain non-essential information that, if removed, would not diminish a reader's ability to understand the research problem being investigated. This is why non-textual elements should not carry over the sequential numbering of non-textual elements in the body of your paper.
• If you have more than three appendices, consider listing them on a separate page at the beginning of your paper . This will help the reader know what information is included in the appendices [always list the appendix or appendices in a table of contents].
• The appendix can be a good place to put maps, photographs, diagrams, and other images , if you feel that it will help the reader to understand the content of your paper, while keeping in mind the study should be understood without them.
• An appendix should be streamlined and not loaded with a lot information . If you have a very long and complex appendix, it is a good idea to break it down into separate appendices, allowing the reader to find relevant information quickly as the information is covered in the body of the paper.

II.  Content

Never include an appendix that isn’t referred to in the text . All appendices should be summarized in your paper where it is relevant to the content. Appendices should also be arranged sequentially by the order they were first referenced in the text [i.e., Appendix 1 should not refer to text on page eight of your paper and Appendix 2 relate to text on page six].

There are very few rules regarding what type of material can be included in an appendix, but here are some common examples:

• Correspondence -- if your research included collaborations with others or outreach to others, then correspondence in the form of letters, memorandums, or copies of emails from those you interacted with could be included.
• Interview Transcripts -- in qualitative research, interviewing respondents is often used to gather information. The full transcript from an interview is important so the reader can read the entire dialog between researcher and respondent. The interview protocol [list of questions] should also be included.
• Non-textual elements -- as noted above, if there are a lot of non-textual items, such as, figures, tables, maps, charts, photographs, drawings, or graphs, think about highlighting examples in the text of the paper but include the remainder in an appendix.
• Questionnaires or surveys -- this is a common form of data gathering. Always include the survey instrument or questionnaires in an appendix so the reader understands not only the questions asked but the sequence in which they were asked. Include all variations of the instruments as well if different items were sent to different groups [e.g., those given to teachers and those given to administrators] .
• Raw statistical data – this can include any numerical data that is too lengthy to include in charts or tables in its entirety within the text. This is important because the entire source of data should be included even if you are referring to only certain parts of a chart or table in the text of your paper.
• Research instruments -- if you used a camera, or a recorder, or some other device to gather information and it is important for the reader to understand how, when, and/or where that device was used.
• Sample calculations – this can include quantitative research formulas or detailed descriptions of how calculations were used to determine relationships and significance.

NOTE:   Appendices should not be a dumping ground for information. Do not include vague or irrelevant information in an appendix; this additional information will not help the reader’s overall understanding and interpretation of your research and may only distract the reader from understanding the significance of your overall study.

ANOTHER NOTE :  Appendices are intended to provide supplementary information that you have gathered or created; it is not intended to replicate or provide a copy of the work of others. For example, if you need to contrast the techniques of analysis used by other authors with your own method of analysis, summarize that information, and cite to the original work. In this case, a citation to the original work is sufficient enough to lead the reader to where you got the information. You do not need to provide a copy of this in an appendix.

III.  Format

Here are some general guideline on how to format appendices . If needed, consult the writing style guide [e.g., APA, MLS, Chicago] your professor wants you to use for more detail:

• Appendices may precede or follow your list of references.
• Each appendix begins on a new page.
• The order they are presented is dictated by the order they are mentioned in the text of your research paper.
• The heading should be "Appendix," followed by a letter or number [e.g., "Appendix A" or "Appendix 1"], centered and written in bold type.
• If there is a table of contents, the appendices must be listed.
• The page number(s) of the appendix/appendices will continue on with the numbering from the last page of the text.

Writing Tip

Consider Putting Your Appendices Online

Appendices are useful because they provide the reader with information that supports your study without breaking up the narrative or distracting from the main purpose of your paper. If you have a lot of raw data or information that is difficult to present in textual form, consider uploading it to an online site. This prevents your paper from having a large and unwieldy set of appendices and it supports a growing movement within academe to make data more freely available for re-analysis. If you do create an online portal to your data, note it prominently in your paper with the correct URL and access procedures if it is a secured site.
