As we will see shortly, in most cases, if you use factor-variable notation, you do not need to create dummy variables. Dummy variables are variables that divide a categorical variable into all its values, minus one. One value is always left out in a regression analysis, as a reference category. B-coefficients for the new variables will then show the expected differences in relation to the reference category.
