Other features:

PRINT procedure

WHERE= data set option

Data set:

orders observations in the output data set by descending _TYPE_ value
outputs the mean exam scores and mean final grades without assigning new variables names
outputs the median final grade to a new variable
displays the output data set.

Program

options nodate pageno=1 linesize=80 pagesize=60;

proc means data=Grade noprint descend;

   class Status Year;

   var Score FinalGrade;

   output out=Sumdata (where=(status='1' or _type_=0))
          mean= median(finalgrade)=MedianGrade;
run;

proc print data=Sumdata;
   title 'Exam and Course Grades for Undergraduates Only';
   title2 'and for All Students';
run;

Output

The first three observations contain statistics for the class variable levels with a status of 1. The last observation contains the statistics for all the observations (no subgroup). Score contains the mean test score anf FinalGrade contains the mean final grade.
