AVERAGEIF

Can I do averageif like below?

=AVERAGEIF(B:C,"aa",A:A)

(1+3+5)/3 = 3

If not, what can I do?

Thanks a lot.

Saqib Husain

=AVERAGEIF(B:B,"aa",A:A)+AVERAGEIF(C:C,"aa",A:A)

...Hey Saqib!.....but won't that give you 1+4 = 5?

To get the average overall try an array formula e.g.

=AVERAGE(IF(B1:C5="aa",A1:A5))

confirmed with CTRL+SHIFT+ENTER

Sorry I forgot to mention that if b and c are same then count as 1

Still = (1+3+5)/3 = 3 ?

Is it possible?

I forgot to say why your initial AVERAGEIF function doesn't work - AVERAGEIF works on a 1 cell to 1 cell basis so even though you only used A:A as the range to average your average range is actually 2 columns so when C3 is "aa" the formula is trying to add B3 (not A3) to the average (and because that's text it's ignored)

ssaqibh,

=AVERAGEIF(B:B,"aa",A:A)+AVERAGEIF(C:C,"aa",A:A) = 5

It's not = 3

Hi Barry,

So I must separate each columns (b, c). If I have more columns, then I need to add it 1 by 1, right?

barry houdini

For a small number of columns I would do it as per my suggestion, testing each column individually.....but if you have a large number of columns there are ways that don't involve splitting them all out, e.g. to average A1:A5 as before but based on data in B1:Z5 try this formula

=AVERAGE(IF(MMULT((B1:Z5="aa")+0,TRANSPOSE(COLUMN(B1:Z5)^0)),A1:A5))

confirmed with CTRL+SHIFT+ENTER
