Matched pair analysis for categorical survey responses before/after a treatment

Nov 17, 2024 08:15 AM (604 views)

Hi I have the results of a survey given both Before and After a treatment.

 

For the continuous outcomes the Specialized Modeling -> Matched Pairs is straightforward to obtain paired t-tests, with the N = # of matched pairs.

 

But I am struggling with the best way to test the categorical variables, esp. since there are unequal proportion for the Before and After survey responses, ex. 50 Before and 200 After.

 

I have the data arranged in both Before/after vertically (long) and paired (wide) formats. 

 

Thanks!
