I need to calculate the averages of a range without counting

[afs24]

I'm trying to calculate the average of a range of cells with the numbers (ex: 200,300,0,0). The answer should be 250 not 125 when dividing by 4. Zero shouldn't count because there's always a number for in spreadsheet. I'm adding up the sum of the four numbers and dividing it by the count but it's counting the zero? HELP????

Let A2:A10 house the numbers of interest.

=SUM(A2:A10)/MAX(1,COUNT(A2:A10)-COUNTIF(A2:A10,0))

will produce the desired average of non-zero numbers.

With your numbers in A1 to A4, in A5

=SUMIF(A1:A4,">0")/4

gives 125

In the answer supplied by Vog(tm), if one of the numbers in the data base is less than 0 the answer would be different than in the answer supplied by Aladin. Also if the quantify of data is different than 4, you would have to modify that to the new total data counts .....Aladin's answer seem to account for both issue within the formular.

Good point plettieri.

=SUMIF(A1:A4,"<>0")/4

works correctly with negative numbers.

[...]

=SUMIF(A1:A4,"<>0")/4

works correctly with negative numbers.

The question afs24 posed is:

The SUMIF formula doesn't satisfy the requirements: It would just produce 125 as average when applied to: {200,300,0,0} entered in A1:A4, while

=SUM(A1:A4)/MAX(1,COUNT(A1:A4)-COUNTIF(A1:A4,0))

will produce the desired average of 250.

This formula "works correctly with negative numbers" too, as it should:

Enter {-200,300,0,0} in A1:A4...

The result should be 50 by afs24's specs.

Thank you. I must learn to read and think before posting (twice!).

P.S. this does work

=SUMIF(A1:A4,"<>0")/COUNTIF(A1:A4,"<>0")
