Compute new variable

Postby Sundaygirl » Tue Jul 29, 2014 3:50 pm

Hi, I have pre and post test results, 12 questions in each, that I need to compute into a new variable to show the total score pre and post but only for those users who supplied an answer for each of the 24 questions. Can anyone help me please as I have a very short deadline? Many thanks.

For a super fast way to do that, use the NMISS function for the non missing condition in an IF command for computing the sums. See

Like so you'll easily make your tight deadline :-D
