PLEASE help (this one should be easy...)

**freefaller6** · 04-02-2013, 12:06 PM

Hello esteemed Excel Wizards, I am working on a spreadsheet and have met my match with a particular formula, and would be forever grateful to get some assistance. This seems pretty easy to me, so I am a bit frustrated I cannot figure it out...Anyway, I have ten cells, say H3:H12. In those ten cell are a mixture of numbers, and some have words.

I would like to take the average of that range (if the value is a number), but exclude the max and min outliers from the average. For example, if the values are 1, 2, 3, 4, #NUM, #VALUE, 5, #ERROR, 6, 7; I want the formula to throw out 1, 7, #NUM, #VALUE, and #ERROR (because they are not numbers), and average 2,3,4,5,6.

Please help me, I'm stumped. Thanks!

hi and welcome to the forum

We would love to help you with your question, but 1st, please rename your thread to something more meaningful, that actually describes your problem.

Because thread titles are used in searching the forum it is vital they be written to accurately describe your thread content or overall objective using ONLY search friendly key words. That is, your title used as search terms would return relevant results.

Many members will look at a thread title, and if it is of interest to them, or it falls within their area of expertise, they might only open those threads.

Look at it this way...if you typed that title into google, what would you expect to get back?

=TRIMMEAN(IF(ISNUMBER(H3:H120), H3:H12), 2/COUNT(H3:H12))

The formula MUST be confirmed with Ctrl+Shift+Enter.

Please take a few minutes to read the forum rules about thread titles, and amend yours accordingly.
