How do I average a range of numbers between two criteria? For instance, I'd
want to average only numbers greater than 5 and less than 15.

=(SUMIF(A1:A5,"5")-SUMIF(A1:A5,"=15"))/(COUNTIF(A1:A5,"5")-COUNTIF(A1:A5,"=15"))

In Excel 2007 and later you can use the AVERAGEIFS function

If you are using Excel 2007 you can use the SUMIFS function. It isn't in 2003.

If you have Excel 2007, use the Averageifs function, as in:
=AVERAGEIFS(C7:C11,C7:C11,"5",C7:C11,"<15")

Hi,

Try this

=sumproduct((A2:A105)*(A2:A10<15)*(A2:A10))/sumproduct((A2:A105)*(A2:A10<15))

Guys,
yes it is possible to do it by combination any of the formulae Sumif/countif, averageif, sumproduct.

any idea on the performance of the formulae, which runs in shorter period. I know it doest time long time btw any of the function to excute. But imagine if you have lacs of cells in mutiple spreadsheet, even single milli second is a matter in performance.
