    Question Please help- parametric if nonparametric test?




    I have a data set of 58 records.

    Question 1: I want to view compare mean SAT scores by male/female. 40% of the records are Male, 60% female.

    If I want to compare means of male/female for EACH SAT part (reading/writing, etc.), should I use a t-test or a non-parametric test? I know the Wilcoxon Rank Sum is a cousin of the t-test; however, I believe one of the assumptions is that the distributions are the same and when I did histograms for each parts, for some the distributions were not the same.

    Or should I use one test for those that appear to have the same distribution and different one for those that have different distributions?

    Question 2:
    I'd like to know the answer to this regardless of whether I use Wilcoxon or not, I'd like to know the answer to this -- how would I state my hypothesis if using the rank sum?
