Excel AVERAGE function
Greeting,
I have a list of integer value, and am wondering how to get the average of the list but discarding the min and max from the list.For example: list: 11 3 3 1 Average: 3 because (3 + 3) / 2 = 3 I don't want use macro. Can it be achieved in one Excel formula? Thanks Tom |

If the numbers are in cells A1:A10 (change as appropriate) then
=(SUM(A1:A10)-MAX(A1:A10)-MIN(A1:A10)/(COUNT(A1:A10)-2) should do it (unless perhaps you have special rules about what should happen if the min or max values occur more than once).

Hello Tom,
From your post, my understanding on this issue is: you wonder how to get an average of a set of numbers after throwing out the highest and the lowest values with one formula. If I'm off base, please feel free to let me know. If you do not care when min or max values occur more than once, we can use Andrew and Dan's great ideas: =(SUM(A1:A6)-MAX(A1:A6)-MIN(A1:A6))/(COUNT(A1:A6)-2) -or- =TRIMMEAN(A1:A6,2/COUNT(A1:A6)) If you want to discard all the occurrence of the max and min values, we can consider the AVERAGEIFS function new to Excel 2007: =AVERAGEIFS(A1:A6,A1:A6,"<"&MAX(A1:A6),A1:A6,""&M IN(A1:A6)) Please let me know if you have any other concerns, or need anything else.
