Final answer:
The Appendix of the final report contains detailed backup data and analysis to allow others to follow up on the research presented.
Step-by-step explanation:
The part of the final report that includes backup data or details of the analysis to allow others to follow up is the Appendix. The Appendix contains materials that are related to the main content of the report but are too detailed or lengthy to include in the main body. It can include raw data, detailed calculations, technical figures, or questionnaires used in research. These supplemental materials provide transparency to the research process and enable others to validate or further investigate the findings presented in the report.
In contrast, the Review and analysis section interprets the results, the Recommendations provide a course of action based on the findings, the Executive summary condenses the essential points for quick reading, and the Lessons learned outlines the insights gained from the report's findings.
