Here’s where you can apply the information in one of this chapter’s tips and get a chance to predict a Super Bowl winner! Coach Kent is curious to know whether the average number of games won in a year predicts Super Bowl performance (win or lose). The X variable is the average number of games won during the past 10 seasons. The Y variable is whether the team has won the Super Bowl during the past 10 seasons. Here are the data:
a. How would you assess the usefulness of the average number of wins as a predictor of whether a team ever won a Super Bowl?
b. What’s the advantage of being able to use a categorical variable (such as 1 or 0) as a dependent variable?
c. What other variables might you use to predict the dependent variable, and why would you choose them?
