Hypothesis 1: Job stress is associated with absenteeism rates atwork.

1. What type of relationship would you predict (positive linear,negative linear, and so on)?

2. Graph and label the relationship you predict. State aprediction based on the relationship

shown by your graph.

3. Which method (experimental or nonexperimental) would you useto test this hypothesis?

Why?

4. Which is the independent or “cause” variable and which is thedependent or “effect”

variable?

5. State an operational definition for each variable. Ifexperimental, describe how the

independent variable might be manipulated and the dependentvariable measured. If

nonexperimental, describe how both variables might bemeasured.
