Final answer:
Encoded and plain language supplementary data that elaborates on the report's body is typically included in an appendix, which allows for a clear and focused report while providing additional details for those interested.
Step-by-step explanation:
Encoded and plain language information that elaborates on data in the body of a report is typically appended to an appendix. The appendix serves as a section where related documents and information that are not central to the report's main discussion are included. This allows the report to remain clear and focused while providing the reader with the opportunity to delve into more detailed data if they choose to. Appendices can contain a variety of supporting materials like charts, tables, questionnaires, detailed descriptions, or any additional background. They act as a repository for supplementary materials that the writer deems valuable for a deeper understanding of the content presented in the body of the report but would otherwise clutter the report's narrative.
When writing a formal analytical report, after you complete the body, you may decide to include several optional elements such as letters of transmittal, title page, acknowledgments, and of course, the appendix. These components help to structure your report in a way that is easily navigable and comprehensive for your audience. By adding an appendix, you ensure that all necessary information is available without overwhelming the main sections of your report, thereby maintaining a clear and concise delivery of your research findings.
