This video provides a walkthrough of dummy coding of multicategorical predictors in linear regression. I begin with a simple example using gender identification as a predictor of life satisfaction to lay the groundwork for the later demonstrations where I use the multicategorical variable 'marital status' as a predictor of life satisfaction. In this video I also compare results using dummy coding with results obtained by way of independent samples t-tests, one-way ANOVA, and one-way ANCOVA.
