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. 13 123 24 35 35 46 46 57 57 58 6 79 79 79 78 57 46 35 24 32 |

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) best wishes -- Bernard V Liengme www.stfx.ca/people/bliengme remove caps from email wrote in message oups.com...

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. -- Stan Brown, Oak Road Systems, Tompkins County, New York, USA http://OakRoadSystems.com/ |
