Final Answer :
Explanation :
Dummy variables are created to represent the qualitative predictor variable in a regression model. They are binary variables that take a value of either 0 or 1 to represent the presence or absence of a certain level of the qualitative variable. This allows for the inclusion of qualitative variables in a regression model.
