How can I obtain the average of the middle quartile of an array?
Hi,
Try the following array formula: =AVERAGE(IF((A1:A8QUARTILE(A1:A8,1))*(A1:A8<QUART ILE(A1:A8,3)),A1:A8,"")) Press Shift+Ctrl+Enter to enter it. You my change the to = but I leave that up to you. -- If this helps, please click the Yes button Cheers, Shane Devenshire "nick" wrote: I have a list of numbers and I want to discard the first and last quartile, and then obtain an average of whats left.

How can I obtain the average of the middle quartile of an arra
Hey guys,
Thanks for all your replies. Unfortunately none of them give me the correct answer. To be more precise, I need Excel to calculate the Interquartile Mean (http://en.wikipedia.org/wiki/Interquartile_mean) from an array which is randomly ordered. Any further help would really be appreciated! Thanks again, Nick |
