Dear all,
This must be relatively simple to do this but I cannot figure how.
Suppose I want 100 subjects (and not more) to answer my survey. I want to create a variable ('var') that takes a value for 50 of them (e.g., var=1), and a different value for the remaining 50 (e.g., var=2). In other words, for 50 of the 100 subjects var=1 and for the remaining 50 var=2.
I don't want anything probabilistic, I want to have exactly 50 subjects for which var=1 and exactly 50 for which var=2.
The two groups of 50 can be randomly determined or determined by ResponseID (or some analogous variable).
Thank you very much for your help. Let me know if I haven't been clear enough.
