average the list base on condtional

Sorry for off-topic interjection:

Although there is no official rule regarding this behavior, we request that wherever possible both the question AND the answer be provided in substantive detail here within the thread. An attached workbook is an excellent aid for posing a question and offering a solution, but solely doing that with no in thread explanation makes it difficult for researchers to understand or consider the Q & A of this thread without downloading what may be a pointless doc to them, if they can do that at all. Doing that also hides the content from search engines so others may never benefit from this.

I'm sure you understand, and we look forward to seeing you post your formulas/macros in your posts for the searching benefit of all.

Thanks again for all your hard work here!

How on earth do you get an average of 81.2, when the highest value in the entire range is only 11.3? Even if I SUM all those values, I still only get 60.9. You are going to need to give far more details - and a few examples - of what you want

I have attached a sheet with what I believe is what you want. I don't have much experience witrh Right-ro Left screens, so the formulas as typed here might not correspond exactly with what you see!! Hopefully you'll get the point, though!!!

To return the values on the original sheet:
=IF(COUNTIF($E$2:$E2,$E2)=1,AVERAGEIF($E:$E,$E2,F:F),"")

To copy non-blanks to a new sheet:

=IFERROR(INDEX(Sheet1!L:L,SMALL(INDEX((Sheet1!$L$2:$L$42="")*10^10+ROW(Sheet1!$L$2:$L$42),0),ROW(1:1))),"")

It is used to select cells that contain something (as opposed to blanks) and return them by row number order: SMALLest to largest.

Glad to have helped! If that takes care of your original question, please select Thread Tools from the menu link above and mark this thread as SOLVED. It'd also be appreciated if you were to click the add Reputation button at the foot of any of the posts of those who helped you reach a solution.
