I have values in an Excel file like this:
QR | QR AVG | val1 |
q1 5
q1 3
q1 4
q2 7
q2 9
q3 10
q3 11
q3 12
q3 11
q4 5
q5 5
q5 7
And I would like the QR AVG field to represent the average value partitioned by different QR values. In other words, I'd like to have the following values after my calculation:
QR | QR AVG | val1 |
q1 4 5
q1 4 3
q1 4 4
q2 8 7
q2 8 9
q3 11 10
q3 11 11
q3 11 12
q3 11 11
q4 5 5
q5 6 5
q5 6 7
Where I don't know the exact number of rows that I will have, and I will be intermittently adding rows randomly into the table.
I would prefer not to write a macro to do this if possible. Any idea how I might go about this?
Try this: =AVERAGEIF($A$2:$A$13,A2,$C$2:$C$13)
That should go in column B (QR Average) in each cell. The middle param will automatically change, of course.
Try this function adjusting ranges inside:
=AVERAGEIF($A$2:$A$17,A2,$C$2:$C$17)
Create a pivot table at the same spreadsheet.
Select columns A, B and C (Sheet1!$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:
