Dissertation Appendix Guide: What to Include & Examples by Discipline

Home / Blog / Dissertation Appendix Guide: What to Include & Examples by Discipline

A dissertation appendix contains supplementary material too bulky for the main body — things like survey questionnaires, interview transcripts, raw data, consent forms, code, and visual materials. Each appendix must start on a new page, be labeled (Appendix A, Appendix B, etc.), be referred to in the main text, and appear after your references (unless your institution requires otherwise). What actually goes in depends heavily on your discipline.

The Appendix You’re Probably Underestimating

You’ve spent months (maybe years) collecting data, conducting interviews, running analyses. Now you’re staring at a wall of research materials that don’t fit cleanly into your chapters. Should you delete them? No. Should you cram them into your results chapter? Also no.

The appendix exists for exactly this problem. It’s your back room — a place to put supporting materials that would distract from your main argument if they appeared in the body of your dissertation, but which reviewers and examiners want to see to validate your work.

Here’s what most students get wrong: they treat appendices as an afterthought. But a well-organized appendix actually strengthens your methodology by showing your work is transparent, rigorous, and reproducible.

Let’s break down exactly what belongs in each section, how to label them, and what different disciplines expect.

What Is a Dissertation Appendix?

An appendix (plural: appendices) contains information that supplements your dissertation but would be distracting or inappropriate to include in the main text. Think of it as optional reading — the loss of an appendix won’t affect your main conclusions, but its presence demonstrates thoroughness.

The key rule? Every appendix must be referred to in the body of your dissertation. If you mention “Appendix A” somewhere in your text, the examiner will know exactly why it’s there and where to look.

According to the APA Publication Manual (7th edition), appendices contain materials such as:

Detailed instruments (questionnaires, interview protocols)
Raw data or extended calculations
Supplementary visual materials (maps, photographs, flowcharts)
Ethical approval documentation
Letters or correspondence

Importantly, appendices don’t count toward your word count. This means you have freedom to include detailed materials without worrying about padding your main chapters.

When Should You Include an Appendix?

Not every dissertation needs appendices. You should include them when you have:

Instruments too lengthy for the main text (complete survey questionnaires, detailed interview schedules)
Raw data that supports your results (extended statistical outputs, raw interview transcripts)
Visual materials referenced in-text but too large or numerous to reproduce in chapters
Ethical approval documentation that examiners want to verify
Copyright permissions or correspondence relevant to your methodology

What not to put in appendices:

Data you’ve already summarized in your results section (that belongs in the main text)
Supplementary literature or background reading (that belongs in your literature review)
Anything that’s essential to understanding your argument (if readers need it to follow your logic, it goes in the main body)

What we recommend: When in doubt, ask your supervisor. Some departments have specific requirements that override general guidance. A few minutes of clarification now saves hours of reformatting later.

How to Format a Dissertation Appendix

Placement

For dissertations, appendices should be inserted after your reference list unless your department or institution specifies otherwise. Some Humanities departments ask that appendices appear before the bibliography. Always check your submission guidelines first.

Labeling

Label each appendix with a capital letter and a descriptive title:

Appendix A: Survey Questionnaire
Appendix B: Interview Transcripts (Anonymized)
Appendix C: Ethics Approval Letter

If you have only one appendix, label it simply “Appendix” followed by the descriptive title.

Page Setup

Each appendix starts on a new page. The label appears at the top, centered and bold, with the title on the following line, also centered and bold. Then use normal paragraph formatting (double-spaced, left-aligned, same font and margins as the rest of your dissertation).

Numbering Within Appendices

If you include tables or figures inside an appendix, reset the numbering for each appendix. The letter of the appendix replaces the table or figure number in the main text:

First table in Appendix A → Table A1
Second table in Appendix A → Table A2
First table in Appendix B → Table B1

This makes it easy for readers to find and cross-reference supplementary materials without confusion.

Referencing in the Main Text

You must refer to each appendix at least once in the body of your dissertation. Common phrasing:

“The full questionnaire is provided in Appendix A.”
“Interview transcripts can be found in Appendix B.”
“As shown in Appendix C, all participants completed the consent form.”

Order appendices in the sequence they appear in your text. This keeps things user-friendly and makes it easy for examiners to follow along.

Appendix Content by Discipline

What actually goes into your appendices varies significantly depending on your field. Here’s what each discipline typically expects:

Social Sciences (Psychology, Sociology, Education)

Social science dissertations tend to use appendices for research instruments and qualitative data. Typical contents:

Appendix	Content
Appendix A	Complete survey instrument with all question wording, skip logic, and response options
Appendix B	Anonymized interview transcripts (verbatim, with participant IDs replaced)
Appendix C	Participant information sheets and consent forms
Appendix D	Ethics committee clearance letter or IRB approval
Appendix E	Codebook for qualitative coding (themes, definitions, example quotes)

Example entry (Appendix A — survey instrument):

Appendix A: Perceived Stress Scale (PSS-10) — Complete Instrument

Instructions: The following questions are about your past month. Please indicate how often you felt a certain way. Use the scale below: 0 = Never, 1 = Almost Never, 2 = Sometimes, 3 = Often, 4 = Very Often

In the last month, how often have you felt nervous?

In the last month, how often have you felt helpless?
… [full instrument follows]

This is the kind of detail that examiners want to see. If they can verify exactly how you measured your variables, they can assess whether your methodology is sound.

STEM (Science, Technology, Engineering, Mathematics)

In STEM fields, appendices are primarily about reproducibility. Examiners want to know that your calculations are correct and your methods can be replicated. Typical contents:

Appendix	Content
Appendix A	Detailed mathematical proofs or complex calculations that don’t fit in the methodology
Appendix B	Custom source code, scripts, or algorithm pseudocode
Appendix C	Extended data tables, instrument calibration records, or supplementary parameter sets
Appendix D	Supplementary figures (e.g., heat maps, cross-sections, experimental setups)
Appendix E	Links to supplementary datasets hosted on repositories like GitHub or Zenodo

Example entry (Appendix B — source code):

Appendix B: Data Processing Script (Python 3.9)

The following Python script performs outlier detection and normalizes sensor readings before statistical analysis. It uses the scipy and numpy libraries.
import numpy as np
from scipy import stats

def detect_outliers(data, threshold=3.0):
    z_scores = np.abs(stats.zscore(data))
    return np.where(z_scores > threshold)[0]
See GitHub repository for full code: github.com/[username]/thesis-data-analysis

Including reproducible code strengthens your methods section considerably. If another researcher can run your script and get the same results, your work gains credibility.

Humanities (History, Literature, Philosophy)

Humanities dissertations tend toward appendices that provide primary source materials, translations, or visual archives. Typical contents:

Appendix	Content
Appendix A	Original-language transcriptions of letters, diaries, or government documents analyzed in-text
Appendix B	Translations of foreign-language primary texts (side-by-side or consecutive)
Appendix C	Image catalog or visual archive (photographs, archival documents, art reproductions)
Appendix D	Timeline of historical events referenced throughout the dissertation
Appendix E	Glossary of technical terms or archaic vocabulary

What we recommend: If your dissertation relies on rare archival materials, include scanned images or copies alongside your transcription. This gives readers a way to verify that you haven’t taken quotes out of context.

Business and Management

Business dissertations often use appendices for instruments and supplementary analysis. Typical contents:

Appendix	Content
Appendix A	Interview guides or focus group protocols
Appendix B	Company documents or financial statements used as case study data
Appendix C	Statistical output tables (extended regression results, ANOVA tables)
Appendix D	Participant consent and confidentiality agreements
Appendix E	Survey instruments or performance measurement scales

Example entry (Appendix A — interview protocol):

Appendix A: Semi-Structured Interview Guide — Supply Chain Managers

Interviews were conducted between January and March 2024. Each lasted approximately 45–60 minutes and was audio-recorded with participant consent. The following guide was used:

Opening (5 min): Background, consent reminder
Section 1 — Decision-making (15 min): “Tell me about how your team selects suppliers…”
Section 2 — Risk management (15 min): “What concerns do you have about your current supplier base?”
Section 3 — Technology adoption (10 min): “How has your company’s use of data analytics changed?”
Closing (5 min): Final thoughts, gratitude

This level of detail in your methodology appendix helps examiners evaluate whether your data collection was systematic and transparent.

Referencing Materials in Your Appendix

If you included materials you didn’t create yourself, you must reference them. Follow the same citation rules as in your main text:

Include an in-text citation next to the material inside the appendix
Add a full reference to the source in your main reference list

If you created a table or figure using someone else’s data, cite it in the table title or footnote:

Table A1. Sample size distribution by region (author’s own compilation, data from Smith, 2022)

When you mention an appendix in the main text, don’t quote the appendix content directly. Use the label instead:

“…the findings are discussed in detail (see Appendix B).”

Common Appendix Mistakes (And How to Avoid Them)

Mistake	Why It’s a Problem	How to Fix It
Including appendices that aren’t mentioned in the text	Examiners can’t understand why you included them	Every appendix must be called out in the main body
Inconsistent formatting across appendices	Looks unprofessional and suggests sloppy editing	Use the same font, spacing, margins, and heading style throughout
Copying data into appendices that belongs in your results	Redundant and wastes examiner’s time	Summarized data goes in results; raw data goes in appendices
Forgetting to reset table/figure numbering per appendix	Confusing cross-references	Number as Table A1, Table A2, Table B1, etc.
Putting appendices before references (when not required)	Contradicts most department guidelines	Check your submission manual first
Including copyrighted material without permission	Legal risk to you and your university	Obtain written permission; include a copy in your ethics appendix

A Decision Framework: What Goes Where?

Still unsure whether a piece of material belongs in your main text or an appendix? Use this quick checklist:

Is the material essential for understanding your core argument? → Main text
Is it supportive but too lengthy for the main body? → Appendix
Is it already summarized in your results section? → Don’t duplicate; put raw data in appendix
Is it a research instrument you used? → Appendix
Is it supplementary data that validates your findings? → Appendix
Is it background reading or literature? → Literature review, not appendix
