Hello, I am not sure how to correctly phrase my question into a simple subject line.
Basically, I have a survey Question "What is the number of graduate courses you took for training?"
and I have as answers:
0 frequency: 47
1 frequency: 7
2 frequency: 4
3 frequency: 2
6 frequency: 1
I want to do a PROC MEANS on this variable, NUM_CLASSES. So I already did that, I get a mean of 0.4.
Here is my question: I want to get rid of all 47 of the 0's and run a PROC MEANS on NUM_CLASSES without the 0's. How can I do so? I was thinking of creating a new variable in a DATA step and somehow writing a for loop indicating to get rid of the 0's.
Thank you so much! I figure it is relatively simple, but I'm having trouble figuring it out
Use a where statement to exclude observations.
Assuming your variables are:
num_classes - number of class, freq - count (ie 47, 7)
proc means data=have;
var num_classes;
weight freq;
run;
proc means data=have;
where num_classes>0;
var num_classes;
weight freq;
run;

thank you! The freq part didn't work , so I commented it out and the rest of the code worked Thanks!
