An appendix is a section that comes at the end of a report, research project, or dissertation and contains any additional information such as raw data, interview transcripts, or supporting information 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. The information in the appendices is relevant but is too long or too detailed to include in the main body of your work. Appendices are always supplementary to the research paper, and the paper must contain all information including tables, diagrams, and results necessary to understand the research problem. When considering whether to include content in an appendix, keep in mind 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. A separate appendix should be used for each distinct topic or set of data and always have a title descriptive of its contents. Tables, figures, and other non-textual items can also be added as an appendix. If you have more than one appendix, each appendix should be labeled with a letter (A, B, C, etc.) according to where it appears in the paper. The first appendix referred to in the paper would be named Appendix A, and the second appendix referred to in the paper would be named Appendix B. Each appendix must also have a title, and it should begin on a separate page with a page number.
