Thirty anorexic girls were treated with cognitive behavioral therapy (CBT). They were weighed before and after the treatment. The weight gains, which are positive scores, and weight losses, which are negative scores, are given below. A gain of more than zero pounds would confirm whether the treatment worked. Did the group gain more than zero pounds?

Ok I think I got that part but I am confused with the second part
Choose and calculate the appropriate analysis to compare the anxiety levels of the participants in the CBT treatment to those in the psychodynamic treatment using posttest scores only.
Choose and calculate the appropriate analysis to compare the anxiety levels of participants in the CBT group only at pre- and posttest.
. Using these data and those from Week 6: Assignment 2, compare the outcomes for CBT and psychodynamic therapy. Note that you may use SPSS to compute any descriptive statistics you need, but you must compute the significance test by hand.
