Research Question 1:

Introduction:In the Movie data set, we have movie ratings from a variety of websites, such aswww.rottentomatoes.com,(Links to an external site.)

and metascore ratings fromwww.metacritic.com.(Links to an external site.)

Research questions (answer both):

• Which is a better predictor of Rotten Tomatoesmovie ratings:IMDb ratings or Metascore ratings?
• For the variable that correlates with Rotten Tomatoes ratings more strongly, what is the predicted Rotten Tomatoes rating for a movie that has an IMDb rating of 7 and a Metascore of 80? Use Unit 3 concepts to comment on the accuracy of your prediction.

Investigate this question using the data setMovies.txt. Support your answer using concepts from Unit 3.
