1. A student in a research methods course wanted to study motivation. Participants were shown scenarios and were randomly assigned to one group with instructions to either engage in positive self-talk or neutral self-talk. Each participant saw 10 scenarios, 5 with easy tasks and 5 with difficult tasks. They rated how motivated they would be to complete each task on a 5-point Likert scale from (not at all motivated to extremely motivated).

1. What is/are the independent variable(s) in this example?
2. How many levels does/do the independent variable(s) have?
3. Is/are the independent variable(s) manipulated between or within subjects? What information did you use to make that decision?
4. What is/are the dependent variable(s) in this example?
5. What scale of measurement is/are the dependent variable(s) measured using?
6. The student described their study as a 2x3 factorial design. Is that an accurate description? If not- what would the student need to change for it to be correct?
7. What kind of statistical test would be the most appropriate to use to analyze the data from this study (be specific)?
8. When you run that statistical analysis would you be using descriptive or inferential statistics?
9. Give two examples of when you might need to use non-parametric analyses to investigate the data from this study.
