The formula =SUMPRODUCT(--(A1:A100=$F$10), --(B1:B100=%F$11), C1:C100)
will SUM all the C cells having A values equal to F10 and B values equal to
F11
The formula =SUMPRODUCT(--(A1:A100=$F$10), --(B1:B100=%F$11))
will COUNT all the records for which A values equal to F10 and B values
equal to F11
So one over the other will give the average
=SUMPRODUCT(--(A1:A100=$F$10), --(B1:B100=%F$11),
C1:C100)/=SUMPRODUCT(--(A1:A100=$F$10), --(B1:B100=%F$11))
