In this video, we learn about how to set up, execute, and interpret a linear regression procedure that contains two categorical variables by using dummy variables. Note that "dummy variable" is sometimes used to denote the original categorical variable and other times the N-1 variables are created through dummification.

We conduct the regression in Minitab and Excel. It is assumed that you are comfortable with Multiple Regression. If not, please review my entire playlist on that topic. Keep on learning!
