    Is it possible to compute a mean/median score for a Mann Witney test/chi square test?

    Would it be better if I used a t-test here? I forgot to mention the full context: I am doing research at a school. I want to see what effects a certain teaching method has on the students. For this I have one class which is the control group and another class in which I am applying the teaching...
