Estimating Models Using Dummy Variables

Practice how to recode categorical variables so they can be used in a regression model and how to properly interpret the coefficients. 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.

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?
