Excel averageifs with or function

Question

I am using the averageifs function, and have one column where I need to calculate the average if either of the criteria are true.

I have tried using the OR function,

Answer 1

Chancea has given some good techniques I will list one more that avoids array formulas as many will find it easier to read avoiding the sumproduct.

=(SUMIF(I1:I612,"FL",N1:N612)+SUMIF(I1:I612,"IF",N1:N612))/(COUNTIF(I1:I612,"FL")+COUNTIF(I1:I612,"IF"))

Answer 2

AVERAGEIFS extra criteria is a boolean AND operator, it can't perform OR operations. But since your columns do not change we can somewhat implement this ourselves:

Here is a simple way using an array formula (entered with ctrl + shift + enter):

=AVERAGE(IF((I1:I612="IF")+(I1:I612="FL"),N1:N612))

Or if you don't like using array formulas you basically do this manually using SUMPRODUCT and COUNTIF:

=SUMPRODUCT((I1:I612="IF")*(N1:N612)+(I1:I612="FL")*(N1:N612))/(COUNTIF(I1:I612,"IF")+COUNTIF(I1:I612,"FL"))

Answer 3

Do not think Excel has this feature, but in Google Sheets, I've been using the below to achieve similar results

=average(filter($A:$A,($C:$C=$E$6)+($C:$C=$E$7)))

giving me an average of the values in A:A where C:C matches the value in either E6 or E7

unlike an ifs / sumifs etc., the filter uses =, not a comma, thus $C:$C=$E$6 is used, not $C:$C,$E$6

Mathematical symbols are just entered ( so <> rather than "<>"& )
