Usage Note 59251: A discussion of standard errors and standard deviations in the SURVEYMEANS procedure
PROC SURVEYMEANS computes variances of both the mean and the sum, and their square roots are referred to as the standard error of the mean and the standard deviation, respectively. The estimated standard deviation of the sum is the same as the standard error of the sum under the sampling distribution (Kish, 1965 p. 60).
Prior to 9.4 TS1M3 (SAS/STAT 14.1), the printed output column headings in the Statistics table are:
proc surveymeans mean sum;
ods output statistics=stats;
var x;
run;
The following results, obtained from PROC CONTENTS on the output Statistics table, show that the output variable names are StdErr and StdDev:
Beginning in 9.4 TS1M3 (SAS/STAT 14.1), to make the results more clear, we modified the labeling in the printed output. The printed output column headings are now:
In addition, the Statistics table output data set includes variable labels. The output variable names have not been changed so that compatibility with earlier releases is maintained.
Here are the current variable names and attributes:

fixed.
The distinction between "standard error" and "standard deviation", as used in PROC SURVEYMEANS, is explained.
