Averaging excluding min and max numbers

[n_gineer]

I need to take an average of a set of numbers while excluding the 5 highest and the 3 lowest. Is there an easy way?

The *array* formula:

=AVERAGE(LARGE(rng,ROW(INDIRECT("6:"&COUNT(rng)-3))))

To enter an array formula, after typing or pasting it into the formula bar,
hold down <ctrl><shift> while hitting <enter>. Excel will place braces {...}
around the formula.

This formula assumes that a number is only counted once. For example, given
the numbers:

12,12,12,10,10,10,10,10,10,9,9,9,9,9,8,8,7,7,7,7,6,6,5,4,4,4

the formula would exclude the three 12's, two of the 10's and the three 4's
from the average.

Is this what you want?

....

=(SUM(data)-SUM(LARGE(data,{1,2,3,4,5}),SMALL(data,{1,2,3})))/(COUNT(data)-8)
