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.

John is interested in whether there is a relationship between positive views people have of themselves in one aspect of their lives and a positive view people have of themselves in other aspects of their lives. To address this question, he has 80 men complete a self-concept inventory that contains five scales. One scale involves questions about how competent respondents feel in the areas of intimate relationships, (e.g., relationships with friends). The other scale includes items about how competent a person feels in general.

Solution

a.) The variables described are response of the men , self concept inventory that contains five scales in one aspect of life and in other aspect of life.

b.) IV\'s : Self concept inventory that contains five scales

DV\'s : Response of the people

3.) Quantitative

4.) Ordinal

5.) Since John is interested in the relationship between positive views people have of themselves in one aspect of their lives and a positive view people have of themselves in other aspects of their lives, we use the paired t test.
