Hi,

I have about 25 columns and 116 rows all with numbers in them. For each row, i want to add up the z scores for each respective column. I already calculated the average and standard deviation at the bottom of each column. I've tried multiple ways but nothing seems to work. Any help would be appreciated!

Welcome to MrExcel.

I'm no statistician, but wouldn't the sum of the z scores be zero? Example:

=SUM(STANDARDIZE((A1:A10),A11,A12))

confirmed with Ctrl+Shift+Enter.

I'm not adding the zscores all from the same column, rather I'm adding 1 zscore from each column

For example, this is what I tried

=sum(standardize(g2, g118, g119):standardize(ae2, ae118, ae119))

Surprisingly this worked for me:

=SUM(STANDARDIZE((A1:C1),(A$11:C$11),(A$12:C$12)))

confirmed with Ctrl+Shift+Enter. Adjust the references to suit.

After using the ctrl+shift+enter this worked perfectly! Thanks!

One follow up,

Now if I want to multiply each z score by a number, say in row 13 with reference to your formula, how would I adjust it?

I know I would use sumproduct but where would I place the extra data?

Thanks
