使用数据透视表上的名称计算平均值

Question

I'm trying to have the pivot table calculate the average number of employees underneath each supervisor for a specific region. However pivot tables are unable to average out text strings. In the example below, within one region I have 5 supervisors but they all have different numbers of employees under them, some have 1 or 2. But all together there are 7 employees for that region. I need it to average out the number of employees per supervisor: so 7/5 = 1.4 would be the average. Is there any way you can create a count of employee divided by the amount of unique supervisors using a pivot table?

Number of Supervisor to Employee

Answer 1

OK well not very elegant I know but this would do it. Add a helper column which works out the fraction of a supervisor available to each employee (eg 2 employees per supervisor = 1/2, 3 employees = 1/3 etc.) starting in D2:-

=1/COUNTIFS($A$2:$A$20,A2,$C$2:$C$20,C2)

Then you can put the sum of these and the count of any column into a pivot table, putting Region as the row variable, and simply a manual formula to work out the ratio starting in J2:-

=IFERROR(I2/H2,"")

Note:- You can use GetPivotData to get the totals from the pivot table if you prefer. You could also use an array formula to list the distinct values of Region and not use a pivot table, but the pivot is quicker.
