Hello,
I am having trouble creating a basic average function that will average groups of numbers. In the data set pasted below, I would like a function that can be copied to average groups of three numbers so that I don't have to repeat the typing of the function, ie the average of C1:C3, then copying (dragging down) the function so it automatically averages C4:C6. When I try to copy the average function, instead of following this pattern, I will get first an ave. of C1:C3, then C2:C4, etc.
Can someone help?
A B C
1 EGA 1.17
2 EGA 1.15
3 EGA 1.25
4 MRO 1.09
5 MRO 1.08
6 MRO 0.97
7 JVA 1.13
8 JVA 1.12
9 JVA 1.18
Try something like:
=AVERAGE(INDEX($C:$C,1+((ROW(A1)-1)*3)):INDEX($C:$C,3+((ROW(A1)-1)*3)))
copied down until you get errors.
