I'm having real difficulty finding a formula to calculate the last 10 results in a range of cells.
Say I have 10-1 in Cells A1-A10. So 10 in A1, 9 in A2 etc...
I want to find a formula which will calculates the average of these cells, but everyday someone inputs a new figure at the top of this set in A1 by inserting a new cell.
So lets say they add 11 to A1, the rest of the column will have 10 in A2, 9 in A3 etc... all the way to A11. Each day a new figure is added at the top, pushing the others downwards.
Is there a formula which will calculate only the A1 through to A10 averages?
Thanks, Screenshot attached to help visualise.
