Average Function with Day of Week Criteria

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.
 
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)
 
... and a quick sample, in case needed:

Note that the average formula as suggested will ignore empty cells or
formula cells within B1:B200 evaluating to null (""), re - the condition:
.... ($B$1:$B$200<>"") ..

If we need it to ignore cells containing zeros as well,
then we could add-on say, the condition: .. ($B$1:$B$200>0) ..
i.e. put instead in D1, array-enter as before, and copy down to D7:

=AVERAGE(IF(($B$1:$B$200>0)*($B$1:$B$200<>"")*($A$1:$A$200=C1),$B$1:$B$200))
 
Max,

For the OPs information really, but it may not be appropriate to do the
blank test. If a week number is 1 and the value is blank, it may be correct
to include that in the average

=AVERAGE(IF($A$1:$A$200=C1,$B$1:$B$200))

BTW, brought a smile to my face seeing you use cjoint :-))

Thanks for the comments, Bob. Think the options given would enable the OP to
figure out the conditional checks required, and how to add/remove conditions
as may be required.

Ay, it was only the other day that I shared with Roger G the steps on using
cjoint <g>. But I guess savefile.com still remains my primary choice, due to
its other features (project/folder feature for instance).

Yes, savefile does seem to be more permanent, but for simple transient
files, I like the cjoint look and feel.

For uploading cjoint seems much more accessible,
while savefile's quite full of late
