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

Try this: =AVERAGEIF($A$2:$A$13,A2,$C$2:$C$13)

That should go in column B (QR Average) in each cell. The middle param will automatically change, of course.
