Question
1) The variables described in each scenario. 2) The number of IVs and DVs described in each scenario. 3) The nature of the independent and dependent variables described in each scenario, e.g. categorical, quantitative, etc. 4) The measurement system used for each of the variables (IVs and/or DVs) described in each scenario, e.g., nominal, ordinal, interval, or ratio. 5) Select the test statistic that is appropriate for the hypothesis described in each scenario; describe which guide (from the two selection guides in the back of Chapter 2) you used; and your rationale for the selection of the test you did choose. Scenario #1: Ethel is interested in two methods of note-taking strategies and the effect of these methods on the overall GPAs of college freshman. She believes that men would benefit most from Method 1, while women would benefit most from Method 2. After obtaining 30 men and 30 women volunteers in freshmen orientation, she randomly assigns 10 women and 10 men to Method 1, 10 women and 10 men to Method 2, and 10 women and 10 men to a control condition. During the first month of the spring semester, individuals in the two note-taking method groups receive daily instruction on the particular note-taking method to which they were assigned. The control group receives no notetaking instruction. GPAs for all participants are recorded
