Based on the research question you created, complete the following tasks:
- Fit a multiple regression model, testing whether a mediating variable partly or completely mediates the effect of an initial causal variable on an outcome variable. Think about whether or not the model will meet assumptions.
- Fit the model, testing for mediation between two key variables.
- Analyze the output, determining whether mediation was significant and how to interpret that result.
- Reflect on possible implications of social change.
Write a 1- to 2-paragraph analysis.
The research question: “Does the hours of work every week, the level of education and the hours of TV watching every day has a significant effect on income?”
Write a 2- to 3-page critique of the research you found that includes responses to the following prompts:
- Why did the authors use mediation in their multiple regression model?
- Do you think mediation is the most appropriate choice? Why or why not?
- Did the authors display the results in a figure or table?
- Does the results table stand alone? In other words, are you able to interpret the study from it? Why or why not?
