=TRIMMEAN(A1:A10,20%) will eliminate the outlying 20% from your set of 10
data points, so it will lose 1 point from each end of the range.

I have a set of numbers, say in range A1:A10. I've determined that
the maximum and minimum values in this set are outliers and so want to
ignore them when calculating the average.

I know I can ignore either the max OR the min by using one of these
array formulas: =AVERAGE(IF(A1:A10<MAX(A1:A10),A1:A10)) or
=AVERAGE(IF(A1:A10MIN(A1:A10),A1:A10))

How could I combine exclusion of both MAX and MIN?
