What Is an Appendix? How to Create and Format a Thesis Appendix

What Is an Appendix in a Thesis?

An appendix is placed after the main body of a thesis or graduation thesis. It stores materials directly related to the topic that are too long, too detailed, or too disruptive to the reading flow if placed in the main chapters. In a quantitative thesis, an appendix commonly contains the questionnaire, list of items, SPSS or SmartPLS analysis output, data-coding tables, calculation formulas and detailed statistical tables.

You can treat the appendix as the place where readers check how the research was conducted. Chapter 3 explains the method and procedure at the level needed to understand the study. Chapter 4 presents the main findings. The appendices provide the supporting evidence and background materials behind those findings.

An appendix does not replace the main content. If a table is important for answering a research question, it should appear in the results chapter, followed by a more detailed version in an appendix if needed. If you place all results in the appendices and write only “see Appendix” in Chapter 4, readers will have difficulty following your argument.

Appendices are usually placed after the reference list. Some schools require appendices before the references, while others require them at the end of each chapter. Before finalizing the format, check your department’s thesis guidelines and ask your supervisor about any conflicting requirements.

If you are completing the full structure, also check the guide to essay table of contents to make sure the appendices appear in the table of contents with the correct page numbers.

Standard Structure of a Thesis Appendix

An easy-to-read set of appendices needs a title, an identifying number, clear content and links to the main thesis. Do not place every file exported from the software into one appendix simply called “Appendix”. The examiner needs to know which question each appendix helps them check.

The structure below suits a typical quantitative thesis. The page ranges are only estimates because an actual questionnaire or software output may be longer.

Keep appendix titles consistent. You can use “APPENDIX 1. SURVEY QUESTIONNAIRE” or “Appendix 1. Survey Questionnaire”. Once you choose a style, use the same style throughout all appendices.

Each appendix should begin on a new page. If an appendix is very long, divide it into subsections such as “1.1 Introduction”, “1.2 Screening questions” and “1.3 Main scale”. You do not need to number it again as an independent chapter unless your school requires that format.

An English appendix can retain software output titles such as Reliability Statistics, Rotated Component Matrix or Coefficients. Write the surrounding explanation in English as well. If the questionnaire is presented in English, state clearly whether it is the original version, a translated version or a version adapted to the research context.

Steps for Creating a Thesis Appendix

Step 1: Read the school guidelines before formatting

Open your department’s thesis guide and look for requirements on paper size, margins, font, font size, table numbering, page numbering and appendix placement. Some schools require appendices to appear in the table of contents. Others exclude appendices from the maximum page count. These two rules directly affect how you format the document.

If there is no standard template, keep the formatting consistent with the main text. Do not use Times New Roman 13 in the main chapters and a different font in the appendices simply because you pasted output from SPSS into the document.

Step 2: Make a list of the materials for the appendices

Create a separate list containing the questionnaire, coding table, analysis output, supplementary statistical tables and materials that demonstrate the research procedure. Then mark which materials have already been cited in the main text.

A material belongs in an appendix when it meets at least one of three conditions: it is needed to check the method, it is too long for the main chapters, or it was used directly to produce a reported result. Drafts, unused intermediate spreadsheets and screenshots that do not help anyone check the analysis should be removed.

Step 3: Arrange the appendices in the order readers need to check them

A sequence that is usually easy to follow moves from the data collection instrument to the analysis results. Place the questionnaire first, followed by variable coding, scale reliability, EFA, regression or PLS-SEM, and supplementary tables.

If your study uses SmartPLS, organize the appendices in two stages: assess the measurement model first, then assess the structural model. Tables such as Outer Loadings, Construct Reliability and Validity and Discriminant Validity should come before Path Coefficients, R Square, f Square or Bootstrapping results.

Step 4: Export the output and check identifying information

When copying output from SPSS or SmartPLS, check the variable names, model name, number of observations and measurement units. Remove respondent names, phone numbers, email addresses and other unnecessary personal information. If an appendix contains raw data, include only the part that may be disclosed and hide identifying information.

Do not capture the entire software screen if the text becomes too small to read. Export the table to Word, Excel or PDF and adjust the column widths. For a table that is too wide, you can use a landscape page for that appendix only, but keep the page number and title clear.

Step 5: Refer to the appendices in the main text

Each important appendix should be mentioned at least once in the main text. For example: “The questionnaire used to collect data is presented in Appendix 1” or “The detailed Cronbach's Alpha results are presented in Appendix 3.”

The reference must match the actual title. If the main text says “Appendix A” but the title says “Appendix 1”, readers have to guess whether the two labels refer to the same material.

Step 6: Update the table of contents and page numbers last

Update the table of contents only after the content, tables and page breaks are stable. In Word, apply the appropriate Heading style to appendix titles and update the entire Table of Contents. Check the page number of every appendix in the final PDF because page numbers may change after export.

You should also check the list of tables and list of figures if the appendices contain numbered tables or figures. You do not need to add every output table to the list of tables if your department does not require it, but the numbering must remain consistent.

How to write this in your thesis

The sentences below are templates. Replace the text in square brackets with information from your study. Use a template only when the appendix actually contains the material mentioned.

When writing the thesis, you can use the following paragraph and replace the fields: “The questionnaire consists of [number] sections. The [section name] section measures [construct] using [number] items. The complete questionnaire is presented in Appendix [number].”

If you are also preparing the reference list, keep the two tasks separate. An appendix contains materials from your study, while the reference list contains the sources you used. You can review the guides to writing references and citing references to avoid placing sources in the wrong section.

A Short Appendix Example

Suppose you are studying “Factors affecting university students’ intention to use e-wallets”. Chapter 3 describes a questionnaire containing screening information, independent constructs and a dependent variable. Chapter 4 reports Cronbach's Alpha, EFA and regression. The appendix set could be shortened as follows:

Appendix 1. Survey Questionnaire

• Introduction and commitment to protecting respondent information.
• Screening questions: whether the respondent is currently a student and whether they have used an e-wallet before.
• Items for the “Perceived usefulness”, “Perceived ease of use”, “Social influence” and “Usage intention” scales.
• Classification information, including gender, year of study, income or spending amount, where appropriate for the research design.

Appendix 2. Variable Coding

Appendix 3. Analysis Results, illustrative output

The numbers in the table above are illustrative output showing the shape of the software output, not results from a specific study. When you prepare your thesis, replace them with output from your own .sav or .csv file. If the main text reports the Alpha for the Perceived usefulness scale, the appendix must contain the corresponding table, and the reference to “Appendix 3” must match the table of contents.

A useful appendix does not need to contain every number that appeared on your screen. Keep the tables that allow readers to check the procedure, results and decisions to remove or retain items. The explanation, such as “the scale meets the requirement”, belongs in Chapter 4, while the appendix provides the table readers can verify.

Common Errors That Make the Committee Ask Questions

Including an appendix without referring to it in the thesis

The committee may ask which part of the study an appendix supports if the main text contains no link to it. Review each appendix and add a reference in the relevant paragraph instead of placing one general sentence at the end of the chapter.

Removing an important table from the results chapter

If a table is the main basis for accepting or rejecting a hypothesis, present a summary version in Chapter 4. The appendix can contain the full output. Placing the important table only at the end of the thesis leaves the argument without evidence where the reader needs it.

Pasting output with the wrong study title or observation count

This error is easy to detect when you rerun the analysis. Output showing N = 250 while the method says that there are 268 valid questionnaires will immediately raise a question. Before submission, compare the sample size, variable names, number of items and data-exclusion stages across Chapters 3 and 4 and the appendices.

Including personal data in an appendix

A data table containing names, email addresses, phone numbers or identifying codes can create a privacy risk. Hide or delete fields that are not necessary. If your supervisor requests a data check, ask how to submit a separate file instead of placing the complete dataset in the publicly submitted thesis.

Using inconsistent numbering

Common problems include “Appendix A” in the table of contents but “Appendix 1” on the page, inconsistent capitalization, missing page numbers and tables without titles. Create one title format and duplicate it for the remaining appendices.

Using the appendix to cover missing method details

An appendix cannot compensate for Chapter 3 omitting the sampling method, scales, data collection procedure or analysis method. Readers need to know what you did in the main text, then use the appendix to check the details.

Frequently asked questions

What is an appendix, and is it required in a thesis?

An appendix contains the questionnaire, output, coding tables and detailed materials related to the study. Whether it is required depends on the rules of your school, department and supervisor. For a quantitative thesis with a questionnaire and SPSS analysis, an appendix is usually important because it documents the procedure and results.

Does the appendix go before or after the reference list?

The placement depends on the applicable guidelines. Many thesis templates place appendices after the reference list, while some departments require them immediately after the conclusion or before the references. Follow the official template from your institution instead of changing the position based on one thesis found online.

What does a thesis appendix contain?

You can include the questionnaire, variable coding, item list, Cronbach's Alpha, EFA, regression or SmartPLS output, and supplementary tables. Include only material directly related to the topic that can be checked and does not contain unnecessary personal information.

Should I include all SPSS output in the appendix?

You do not need to include every output table. Keep the tables related to the analytical decisions and reported findings, such as Reliability Statistics, Item-Total Statistics, KMO and Bartlett's Test, Rotated Component Matrix, Model Summary, ANOVA and Coefficients. If a table was not used or is only an intermediate output, you can remove it to keep the appendix focused.

How do I format an appendix in Word so it appears in the table of contents?

Use a consistent Heading style for titles such as “Appendix 1” and “Appendix 2”, then update the Table of Contents after completing the page layout. Each appendix should begin on a new page, have a clear title and be referred to by the same name in the main text. After exporting to PDF, check the page numbers because adjusting a table can change the position of an appendix.

Does the appendix count toward the thesis page limit?

That depends on your school’s rules. Some institutions count the entire file, while others count only the pages from the introduction through the conclusion. Check the official guidelines and state the page-count scope if the form requires it. Do not shorten an important appendix because of a page-limit rule that you have not verified.

Open your thesis file, make an appendix list, match each appendix to the relevant chapter, and update the table of contents last. If you need help turning your analysis results into complete thesis chapters, see M5 chapter writing.
