The Story: We are planning to conduct four studies for a client who runs a clinic treating students with behavior disorders. For each description of a data collection and research question, please select the correct statistical model.

This demo includes one of each of the four models we are working with during this portion of the course. However, there is no guarantee that there will be one of each on the quiz!

(a)Will there be a difference in the average rating of "problem behaviors" before vs. after completing a 6-month treatment program. What statistical model would you use analyze these data?

1. WG ANOVA
2. Chi-square
3. can't tell from the information given
4. correlation
5. BG ANOVA

(b)Is there a relationship between how many times a client yells at their therapist and their teacher's rating of "problem behaviors"? What statistical model would you use analyze these data?

1. Chi-square
2. WG ANOVA
3. correlation
4. BG ANOVA
5. can't tell from the information given

(c)We ran a study in which some of the patients received the usual cognitive-behavioral therapy (cog-beh) and other patients received this therapy and also psychotropic medication (cog-beh + meds). Our DV was whether or not they were suspended from school during the next 3 months.

(d)We ran a study in which some of the patients received the usual cognitive-behavioral therapy (cog-beh) and other patients received this therapy and also psychotropic medication (cog-beh + meds). Our DV was the ratings of "problem behaviors".
