If you have supplemental material for your paper that would be useful for your reader but distracting in the body of your paper, you can place this material at the end of your paper in an appendix or appendices. This supplemental material may include large visuals, detailed research study results, surveys, questionnaires, etc.
Always refer to appendices in the body of your paper.
This study displayed the preferred outcome (see Appendix A).
See Appendix B for an example of the survey that was administered.
Each appendix must be on a separate page.
Appendices are placed after the reference page(s).
Labels and titles of appendices should be centered and bold (as a level 1 heading).
Text in an appendix should be left aligned.
Label appendices in the same order that they are mentioned in your paper.
Include the title of the appendix below the label.
