1. A social psychologist is concerned with the violence and aggression in society. She designs a treatment program that includes educational videos, role playing of problem situations, and peer modeling. She is concerned that a person's hostility level will influence how they respond to her program, so she tests her subjects on the Buss Durkee Hostility Inventory and classifies her subjects into low, medium, and high hostility groups. She then randomly assigns subjects in each group to either the treatment program or a control group. This researcher is using a __________ design.
2. Random assignment is to __________ as systematic assignment is to __________.
3. Using the randomized blocks design to test for the impact of fertilizer improves on the simpler two-group design (Al vs. A2) by:
4. A Type I error occurs when:
5. Using homogenous subjects, more reliable measures, and uniform procedures in applying the treatment are all strategies to reduce __________.
6. Alternating the treatments in successive plots (Al, A2, Al, A2, etc.) of a randomized blocks design would be an example of:
7. If a statistical test yields p = .018, Fisher would recommend that the researcher:
8. In psychology, the __________ design is to between-subjects as the __________ design is to within- subjects.
9. To control for the order of presentation of various doses of a drug designed to treat insomnia administered to the people in a within-subjects design, a researcher would be likely to choose which of the following research designs?
10. The significance probability is the probability, ______________, of getting the observed mean difference or an even larger value.
11. Fisher is to __________ as Gosset (Student) is to __________.
12. Brady investigated the effects of stress in his famous "executive monkey" studies. He used shock as the stressor; the executive monkey either received or did not receive a shock dependent upon its behavior. To control for whether the shock alone might produce stress, Brady paired a second monkey with the executive monkey. This second monkey received a shock every time that the executive monkey did. This design, where one subject's behavior controls the outcome of another subject's behavior, is a __________ design.
