One way ..

Put in C1: =ROW()

Put in D1, and array-enter (press CTRL+SHIFT+ENTER):
=AVERAGE(IF(($B$1:$B$200<"")*($A$1:$A$200=C1),$B$ 1:$B$200))

Select C1:D1, copy down to D7

D1 to D7 will return the results
for the corresponding day of week listed in C1:C7
(You'd get the full list for days 1 - 7)

This is for Excel 2000.

I want to compute averages based on the day of the week listed in another
column but within the same row. I already have the day of the week figured
out, column A has numbers 1-7, 1=Sunday, 2=Monday, etc.

What I want is to take the AVERAGE of B1:B200, *if* the value in column
A=1,
or whatever number or numbers I specify.
