An example, in say C2, with formula array-entered**:

=AVERAGE(IF((A2:A10=2)*(A2:A10<=10),B2:B10))

returns the average of col B values
where col A values are between 2 and 10, inclusive

**Press CTRL+SHIFT+ENTER to confirm the formula

Adapt the ranges to suit. Ranges must be identically sized.

I want to average a column where the values of a different column is within
a certain range. How do I set this up? Thanks.
