Calculating an Average of previous rows in the Total
Hello, was having trouble with a calculation so thought I'd drop by here and see if anyone had any ideas to solve the issue.
In the below screenshot of an excel mockup, I have Column A which is a column from one table, and Column B which is a column from a different table, and then A/C which is just a measure which divides Column A by Column B. This is repeated for each year.
The Grand Total would end up summing all of Column A and Column B, then repeating the measure's instructions of dividing A/C which I understand is what it's supposed to be doing, but any suggestions on how I would I go about it if I wanted to take a simple average of all the results of Column A/C? The result of dividing the totals would be 0.05 in this case, but the average of (0.1, 0.025, 0.0833 and -0.05) would be 0.039583 in this example.
