You can use the following methods to calculate the sum of values by group in SAS:

**Method 1: Calculate Sum by One Group**

**proc sql;
select var1, sum(var2) as sum_var2
from my_data
group by var1;
quit;
**

**Method 2: Calculate Sum by Multiple Groups**

**proc sql;
select var1, var2, sum(var3) as sum_var3
from my_data
group by var1, var2;
quit;**

The following examples show how to use each method with the following dataset in SAS:

**/*create dataset*/
data my_data;
input team $ position $ points;
datalines;
A Guard 15
A Guard 12
A Guard 29
A Forward 13
A Forward 9
A Forward 16
B Guard 25
B Guard 20
B Guard 34
B Forward 19
B Forward 3
B Forward 8
;
run;
/*view dataset*/
proc print data=my_data;**

**Example 1: Calculate Sum by One Group**

The following code shows how to calculate the sum of points by team:

/*calculate sum of points by team*/ proc sql; select team, sum(points) as sum_points from my_data group by team; quit;

From the output we can see that players on team A scored a total of **94** points and players on team B scored a total of **109** points.

**Example 2: Calculate Sum by Multiple Groups**

The following code shows how to calculate the sum of points, group by team and position:

/*calculate sum of points by team, grouped by team and position*/ proc sql; select team, position, sum(points) as sum_points from my_data group by team, position; quit;

The resulting table shows the sum of points scored by players based on their team and position.
