**To prepare for Discussion Part 1 :**

- Review this week’s Learning Resources and media program related to multiple regression.
- Create a research question using the General Social Survey that can be answered by multiple regression.

#### By Day 3

Use SPSS to answer the research question. Post your response to the following:

- What is your research question?
- What is the null hypothesis for your question?
- What research design would align with this question?
- What dependent variable was used and how is it measured?
- What independent variable is used and how is it measured?
- What other variables were added to the multiple regression models as controls?
- What is the justification for adding the variables?
- If you found significance, what is the strength of the effect?
- Explain your results for a lay audience, explain what the answer to your research question.

**To prepare for Discussion Part 2 :**

- Review Warner’s Chapter 12 and Chapter 2 of the Wagner course text and the media program found in this week’s Learning Resources and consider the use of dummy variables.
- Create a research question using the General Social Survey dataset that can be answered by multiple regression. Using the SPSS software, choose a categorical variable to dummy code as one of your predictor variables.

#### By Day 3

Estimate a multiple regression model that answers your research question. Post your response to the following:

- What is your research question?
- Interpret the coefficients for the model, specifically commenting on the dummy variable.
- Run diagnostics for the regression model. Does the model meet all of the assumptions? Be sure and comment on what assumptions were not met and the possible implications. Is there any possible remedy for one the assumption violations?
