I have a sample dataset of total outbound calls, it comprises rows (dates) and columns (hourly), my goal is to show totals and average of outbound calls per day (rows), and the totals and average of calls per hour (column). Now, I believe I dont have any problems showing the average of these data per columns and per rows, I can simply use =average function and select the entire row to get the day's average calls, and select the entire column to get the hour's average calls, but my problem is adding the average on the very last part, corner of the table (last row and last column). I wanted to get the average of the average hourly and the average of average per day, but I dont think I can be able to do that at the same time in the same cells (see yellow highligted cell in the screenshot). Is there a correct or standard way of doing this or showing the average on that corner of the table?
