I have the following problem.
I have a group of people where male and female members differ in their score on a certain scale. After an intervention both gender scored higher in a post test 6 months later. The increase in the score for women is roughly 9 % whereas men improvend only roughly 6 %.
What is the appropriate statistical method to test whether the womens' score improved (significantly) more than the mens score did? The increase for men as well as women in itself is stastistically sifnificant
