Question: 1. Most of the problems in this book are already set up for you in tabular form. Researchers, however, usually begin with fairly unorganized raw scores in front of them. For this problem, study the data until you can arrange it into a usable form.

The data are based on the report of Hollon, Thrase, and Markowitz (2002), who compared three kinds of therapy for depression with a control group. I have given you characteristics that allow you to match up a group of four subjects for each row. The dependent variable is Beck Depression Inventory (BDI) scores recorded at the end of treatment. The lower the score, the less the depression. Begin by identifying the independent variable. Study the data until it becomes clear how to set up the analysis. Analyze the data and write a conclusion

Female, age 20                        BDI = 10 Drug therapy

Male, age 30                           BDI = 9 Interpersonal therapy

Female, age 45                        BDI = 16 Drug therapy

Female, age 20                        BDI = 11 Interpersonal therapy

Female, age 20                        BDI = 8 Cognitive-behavioral therapy

Female, age 20                        BDI = 18 Placebo

Female, age 4                          BDI = 10 Cognitive-behavioral therapy

Male, age 30                            BDI = 10 Drug therapy

Male, age 30                            BDI = 15 Cognitive-behavioral therapy

Female, age 45                         BDI = 24 Placebo

Female, age 45                         BDI = 16 Interpersonal therapy

Male, age 30                            BDI = 21 Placebo

2. Look over the objectives at the beginning of the chapter. Can you do them?
