Survey data
You’ve been asked to determine the relationship between the depart-
ment and whether calculus is required as a prerequisite for courses in that
department. First you’ll examine the distribution of professors in different
department categories.
In Excel, you obtain category counts by generating a PivotTable, a work-
sheet table that summarizes data from the source data list (in this case
the survey data). Excel PivotTables are interactive; that is, you can update
them whenever you change the source data list, and you can switch row
and column headings to view the data in different ways (hence the term
pivot).
Try creating a PivotTable that summarizes the number of professors in
each department. You can insert a PivotTable using the commands on the
Insert tab.
