Averaging with a formula

OK, here's a quick easy question. I'm recording the number of times an event occurs in column D. In column E, I'm recording the total of times this event has occurred so far. In column F, I want the average at the end of the day. By this I mean, if by day 3 the even has occurred a total of 9 times at 3 times a day, I want F4 to equal 3. If on day 4 it happens 4 times, I want F5 to equal 3.25 and F4 to remain at 3 for reference. Am I making any sense?

Thanks!

Hi!

If you have the cumulative total is column E, starting in E2, for the
cumulative average, entered in F2:

=IF(E2="","",E2/ROWS($1:1))

Or, just use the AVERAGE function on the daily occurance entries in column
D:

=IF(D2="","",AVERAGE(D$2:D2))

If you will have 1000's of rows of data to include in the calculation you
will want to avoid using the AVERAGE function.

Great! But, is there anyway to simplify the avg? Maybe to only two decimals? 3.33 instead of 3.3333333

=IF(E2="","",ROUND(E2/ROWS($1:1),2))

Or

=IF(D2="","",ROUND(AVERAGE(D$2:D2),2))
