Standard Deviation Enterprise Edition

Enterprise Edition is using the sample size calculation for standard deviation. How do I force it to use the population standard deviation formula?

Hello @cmcquain,

So you're computing a standard deviation from numeric values in a dataset.

If you're using the "Summary Statistics" task in SAS Enterprise Guide, change the "Divisor for standard deviation ..." from "Degrees of freedom" to "Number of observations" as shown below.

However, if you're using a procedure such as PROC MEANS, PROC SUMMARY or PROC UNIVARIATE, then use the VARDEF=n option in the PROC ... statement. Here's an example using PROC MEANS:

proc means data=sashelp.class std vardef=n;
var age;
run;
