researcher is interested in the relationship between Math Ability and job satisfaction. She recruits a large manufacturing company to help her obtain data and identifies 25 employees who took a math test when they originally applied for their job. She administers a job satisfaction survey (with a 0-100% overall score) to these employees and finds a significant positive association (i.e., a correlation) between math scores and job satisfaction.

1. What is the independent variable in this study?

2. What is the dependent variable in this study?

3. Who is in the sample?

4. How could she potentially reduce sampling error?

5. What type of scale (e.g., nominal, ordinal, interval, or ratio) are most math tests (hint, just like this test).

6. Is job satisfaction a categorical or continuous variable?
