Arrays and Average

[PAL]

I am working w/ a table. Lets say 25 rows/3 columns

Col 1 is product name
Col 2 is region name
Col 3 is number of units sold

I would like to get the average number of units for the sum of the products.
So if there are 2 products in the US that sold a combined 15 units, the
average would be 7.5.

I would like to do this for each region.

Please advise on formula. Thanks.

=SUMIF(B1:B25,"US",C1:C25)/COUNT(1/IF(B1:B25="US",MATCH(A1:A25,A1:A25,0)=ROW($A1:A25)-ROW(A1)+1))

it is an array formula, so commit with ctrl-shift-enter

try

=SUMPRODUCT(--(A2:A10="ABC"),--(B2:B10="us"),C2:C10)/SUMPRODUCT(--(A2:A10="ABC"),--(B2:B10="US"))
o
=SUMPRODUCT(--(A2:A10=D2),--(B2:B10=E2),C2:C10)/SUMPRODUCT(--(A2:A10=D2),--(B2:B10=E2))

D2 and E2 are where you type the product name and region

this give you the average of the sum based on product and region
