4. Regression:

CBC Management has several questions: Which has more impact on a movie’s rating: that it is

fact based or that it has one star? How much does each of these factors change the ratings?

Do you expect a fact based movie that does not have any stars to get better ratings than a

fiction movie with one star? Run a multiple regression where the dependent variable is ratings

and the independent variables are star and fact. Use data from all networks, not just CBC

movies. How well does this regression analysis explain the ratings? Justify your answers
