Which therapy works best for depression?  Let's conduct an experiment and compare three different types of therapy - psychoanalysis, CBT, and behaviorism.  Participants will be randomly assigned to one of the three conditions, subjected to a month of therapy, and then have their depression measured.  Conduct the appropriate analysis with Therapy and Group2.  (Total side note - if we really conducted this study we should add a pretest/posttest, but that design is not covered in undergraduate stats).
