$1.$ Excel Workbooks

Your report should contain four substantive observations. $($Described later.$)$

o Each observation should be created using at least three pivot tables to dig progressively deeper into your data. $($Thus$,$ your Excel workbooks should contain at least $12$ pivot tables in total.$)$

Save all of your pivot table$/$chart work. Thus, you will create and save each pivot table so that you can show your work in your Excel workbook for each observation that you reference in your paper. Number each pivot table$/$chart and create a reference to the pivot table$/$chart in your write$-$up$.($Most students create one worksheet per observation. Thus, their workbook would have four worksheets each containing $3+$ related pivot tables$/$charts for the observation being analyzed.$)$
