Get average based on value in another row

Question

I have values in an Excel file like this:

QR  |  QR AVG  |  val1  |
q1                5
q1                3
q1                4
q2                7
q2                


        

Answer 1

Create a pivot table at the same spreadsheet.

Select columns A, B and C (Sheet1!$A:$C). Click "Insert", and then "Pivot Table".

Place QR at "Row Labels" field and Val1 (as average) at the "Values" field.

Then, use in B2:

=VLOOKUP(A2,$E$2:$F$6,2,1)  

Drag the formula to all cells in column B.

It will look like this:
