Part 1. Do different behavioral Therapies (1 = Psychodynamic, 2 = Cognitive-Behavioral, 3 = Exposure and Response Prevention) and different Medications (0 = Placebo, 1 = SSRI, 2 = Zinc Supplement) work separately or together in promoting weight change among patients with anorexia? 1. Is this a between-subjects or within-subjects design? 2. What are the independent variables? a. b. 3. On which scale of measurement (e. g., nominal, interval, etc...) are the independent variables? a. b. 4. How many levels does each factor (i.e., the independent variables) have? a. b. 5. What is the dependent variable? 6. On which scale of measurement (e.g., ordinal, etc...) is the dependent variable? 7. Is this a one-tailed or two-tailed test? n . . 3 8.

Transfer Therapy and Medication to the Fixed Factors box. Under Options, choose Descriptive statistics. 12. Complete the tables below using the output from the instructions above.

Click Display error bars and choose Standard error. 13. Looking at this Figure, which medication had the greatest effect? Zinc Supplement 14. Graphically, is there a main effect for Medication? How can you tell? 15. Graphically, is there an interaction between Therapy and Medication? How can you tell? No, there is not an interaction as the lines do not meet, we can just observe how they get close to each other but do not intersect
