2. Suppose that the researchers are interested in the effect of class size on only female student test scores. They consider using the following method to reconstruct their treatment and control groups: select all female students who have been assigned to small size classes as their new treatment group and select all female students who have been assigned to normal size classes as their new control group. Is this method problematic?
