I have some numbers in a column and I want to take the average of the last
five. If my numbers are in A1:A10 I know I can use the AVERAGE function:
AVERAGE(A6:A10). But the problem is that some of the cells are empty.
What I want to do is take the average of the last five cells in a column, so
long as those cells have numbers in them. So if cell A7, for example, is
empty, I would average A5:A10. If A7 and A8 are empty, I would average
A4:A10. Is there any way that this is possible?
