Multiple Regression: The effect of working hours weekly on income

Section A

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?”

Section B

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?
