by group processing

[timmy555]

I am using by group processing and trying to find the average of a variable I am doing the processing on. So if it was points earned for 5 games with the points being 5,6,7,8,9 How can I find average of these using by group processing?

@timmy555 please be more specific than this. Can you show us some sample data? Do you have some code that you have tried already?

BY group processing means that you have one or more variables used to define the group. When you say "points in  a game" then the likely BY variable would be a TEAM identification. So here is a possible example:

data example;
   input team $  score;
datalines;
A 15
B 26
A 3
B 18
C 3
C 6
C 27
;
proc sort data=example;
  by team;
run;

proc means data=example mean;
   by team;
   var score;
run;

Please note the data step as way of documenting the data and providing something that you can run to create a data set that be used.

BY groups also usually require sorting by the group variables before any analysis.
