Question

I am using average across a range but only want to take cells that:

1. Are a number (isnumber())

2. Who's key match a particular string (form response = dataA)

   I am using

    =AVERAGEIF('Form Responses 1'!$L$2:$L$143, AND(ISNUMBER('Form Responses 1'!L2), 'Form Responses 1'!C3=Data!A3)) 

My issue comes from anything within the and() statement. How do I make sure that it compares and checks the appropriate cells?

Cheers

Answer 1

Is this what you are trying to do?

=AVERAGEIFS('Form Responses 1'!$L$2:$L$143, 'Form Responses 1'!$C$2:$C$143, Data!A3)

It averages in range $L$2:$L$143 the numeric cells where column C matches the key in Cell A3 of worksheet Data .
