How many Standard Deviations above and below the mean each number is.
 

I have a list of numbers in A1:A20 that has a STDEV of 27.6. I need a
formula that I can copy down that will tell me how many STDEV's above
and below each number is. Thanks in advance PJ.

How many Standard Deviations above and below the mean each number is.
 

Assuming by "how many STDEV's above and below each number is", you mean how
many STDEV above/below the average, use
=(A1-AVERAGE($A$1:$A$20))/STDEV($A$1:$A$20)

Bernard,

Thanks you very much. That is exactly what I was looking for.

Assuming by "how many STDEV's above and below each number is", you mean how
many STDEV above/below the average, use
=(A1-AVERAGE($A$1:$A$20))/STDEV($A$1:$A$20)

Or use the STANDARDIZE function:

=standardize(A1, average(A$1:A$20), stdev(A$1:A$20))

Like Bernard, I would not hard-code the 27.6 because if any of the
numbers in column A change you'd have to remember to recompute the
standard deviation. This way it's autmatic.
