You can use **proc univariate **in SAS with the **by **statement to calculate descriptive statistics for each numeric variable in a dataset, grouped by a particular variable.

This procedure uses the following basic syntax:

**proc univariate data=my_data normal;
by group_variable;
run;**

The following example shows how to use this procedure in practice.

**Example: Proc Univariate by Group in SAS**

Suppose we have the following dataset in SAS that contains information about various basketball players:

**/*create dataset*/
data my_data;
input team $ points rebounds;
datalines;
A 12 8
A 12 8
A 12 8
A 23 9
A 20 12
A 14 7
A 14 7
B 20 2
B 20 5
B 29 4
B 14 7
B 20 2
B 20 2
B 20 5
;
run;
/*view dataset*/
proc print data=my_data;
**

We can use **proc univariate **with the **by **statement to calculate descriptive statistics for the **points** and **rebounds** variables, grouped by the **team** variable:

**proc univariate data=my_data;
by team;
run;**

This procedure will produce the following results:

- Descriptive statistics for
**points**for team**A** - Descriptive statistics for
**rebounds**for team**B** - Descriptive statistics for
**points**for team**A** - Descriptive statistics for
**rebounds**for team**B**

Here is what the descriptive statistics looks like for the **points** variable for team **A**:

If you only want to calculate descriptive statistics for one specific variable grouped by another variable, then you can use the **var** statement.

For example, you can use the following syntax to calculate descriptive statistics only for the **points** variable, grouped by the **team** variable:

proc univariate data=my_data; var points; by team; run;

Feel free to specify as many variables as youâ€™d like in both the **var** and **by** statements to calculate descriptive statistics for whichever variables youâ€™d like.
