Task 2 Report Format
For Task 2, I suggest a 3 to 5 page simple report. You can ID your major paragraphs with the sections of the grading rubric to make it easier for the eval folks to find what they are looking for. And I feel strongly that you should embed your required graph and analysis output directly in the report and not make the eval folks go to a separate document. Embedding is easy to do. Just select the graph, copy it, and paste as an image in the report where you want it. Same for the analysis output. Select the table range you want in Excel, copy it, and again paste as an image in the report.
You do not need to include your data in your report. If the data table is not very large, you could paste it in an appendix at the end of your report if you want.
