Hello,

I have a dataset as below:

data have;
input exam $ passed;
datalines;
A 0
A 1
B 1
C 0
D 1
E 0
E 1
;
run;

Using tabulate procedure i am able to generate total counts correctly, but in ColPctn, i would like to have percentages within in each exam. for instance: first row of output should

be 50% (1 passed / 2 all) = 0.5 , and not 

This is the code i am using below  :
title "CrossTab";

proc tabulate data = have;
class exam;
var passed;
table exam ,
passed*( N SUM='Passed'*f= 10. colpctn);
keylabel all = "Total";
run;

and the output which is not coming as i need:

  passed
N Passed ColPctN
exam 2 1 28.57
A
B 1 1 14.29
C 1 0 14.29
D 1 1 14.29
E 2 1 28.57

I would appreciate any suggestion .

Percentages can be tricky but in this case there is an easy solution:

proc tabulate data = have;
class exam;
var passed;
table exam ,
passed*( N SUM='Passed'*f= 10. mean='% Passed'*f=percent8.2);
keylabel all = "Total";
run;

When dealing with a 0/1 variable, the mean is the same as the percentage of "1" values.
