Definition. 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.
Just so, how do you write an appendix for a 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.
