Dear Members;

I have Pre and Post intervention data on 12 questions. I have calculated Median for all the 12 questions and applied the Wilcoxon test separately for all the questions. The compiled results are presented in a table. You can see that in question Q7 and Q8, P value (P<Z) is <0.0001. But I am not sure what alternative hypothesis is being tested in both the questions?
