1. Add original data
The appendix should be used to put in the original data you collected during the research of the paper. You should add any original data that you think is relevant to the paper, especially if it helps to support your findings. Add only raw data related to the information mentioned or discussed in the paper, because you need to ensure that these data are meaningful to readers.
The original data may include the sample calculation you mentioned in the text of the paper, as well as special data used to expand the data or information discussed in the paper. Raw statistics can also be added to the appendix. You can also use other sources to add information to your paper, which will help support your findings. Ensure that information obtained from other sources is correctly cited.
2. Add supporting graphics, charts or images.
Appendices should also include visual supporting documents, such as charts, graphs, images, maps, drawings or photographs. Only add visual files to your paper that can support your findings.
You can add your own graphs and charts or graphs and charts from other sources. Ensure that all non-original visualization files are correctly referenced in the appendix.
3. Indicate the research tools in the appendix.
You need to mark the tools used in the research. It may be a video camera, a tape recorder, or any other device that helps you collect information. This will help readers understand how you use these devices for research. For example, you can note in the appendix: "All interviews and investigations were conducted by myself in a private environment and recorded with a tape recorder."
4. Add interview papers or surveys.
The appendix should also include the manuscripts of all interviews or surveys as part of the study. Ensure that the manuscript covers the whole interview, including interview questions and answers. You can attach a copy of the handwritten survey or a saved copy of the survey completed online. You should also join all your correspondence with the topic, such as emails, letters or notes between you and the topic.
