JMP 9.0.2: Analyzing pre- and post- questionnaires
Apr 26, 2012 5:43 PM(1392 views)
I am very new to JMP and was hoping someone could verify my method to analyze pre- and post-workshop questionnaires.
My columns for my data table looks like this:
ID# K1 PRE K1 POST K2 PRE K2 POST K3 PRE K3 POST...K10 PRE K10 POST K PRE TOTAL K POST TOTAL
I scored the questions (1=incorrect, 2=correct) and want to test whether or not the change between the pre and post questionnaires were significant. I used Analyze-->Matched Pairs with "K PRE TOTAL" and "K POST TOTAL" for the Y, Paired Response. Did I do it right?
Also, if questions K1 through K5 were health questions and K6 through K10 were welfare questions, is there a way for me to determine whether performance in one section of related questions was better than the other?
