Instructions:

For this week, the format will be slightly different from the ensuing assignments. This week, using the decision tree described in Chapter 21 of the Howell text and any other information that may help, complete the following exercises at the end of Chapter 21: 21.4, 21.6, 21.7, 21.10, 21.13, 21.14, 21.22, and 21.24. For each of these research scenarios, answer the following questions:

Identify the presumed research question(s).
Does the research question appear to be about differences between or among groups or about the relationship, including prediction, between or among variables?
Describe all variables and the measurement scale associated with each variable.
If the research question is about group differences, are the groups composed of different participants (between subjects) or the same subjects (matched or repeated measures)?
Identify, if applicable, the independent variable(s) and the dependent variable(s).
After addressing the questions above, associate with each exercise the most likely statistical procedure from the list below and justify your selection.
- Single sample t-test.
- Two-sample independent t-test.
- Two-sample correlated t-test.
- One-way ANOVA.
- Factorial ANOVA.
- Repeated measures ANOVA.
- ANCOVA.
- Pearson correlation (r).
- Bivariate regression.
- Multiple regression.
- A non-parametric statistical procedure for group differences.
- A non-parametric correlation.
  At this point in the course, you are not expected to be familiar with all of the statistical procedures above. You may need to survey the text to get an overview of the application for some of these procedures. The point of this assignment is not to be able to obtain the only "right" answer, but to be able to engage in a consistent and logical process to identify the appropriate statistical procedure(s) for any particular research question.
