Computing Statistics for Numeric Variables
Selecting Statistics and Variables


Procedure Syntax

The MEANS procedure can include many statements and options for specifying needed statistics. For the sake of simplicity, let's look at a few key statements and consider the procedure in its basic form.


General form, basic MEANS procedure:
PROC MEANS <DATA=SAS-data-set>
<statistic-keyword(s)> <option(s)>;
RUN;

where

  • SAS-data-set identifies the data set to process
  • statistic-keyword(s) specifies the statistics to compute
  • option(s) control the content, analysis, and appearance of output.


In its simplest form, PROC MEANS prints the n-count (number of non-missing values), mean, standard deviation, and minimum and maximum values of every numeric variable in a data set.
     proc means data=perm.survey;
     run;
