11.33 Look at the data.
CASE 11.2 Examine the data for total U.S. revenue, budget, opening-weekend revenue, and the number of opening-weekend theaters. That is, use graphs to display the distribution of each variable and the relationships between pairs of variables. Based on your examination, how would you describe the data? Are there any movies you consider to be outliers or unusual in any way? Explain your answer.
11.33
U.S. Revenue, Budget, and Opening are all rightskewed. Opening has a large outlier that may be influential. Theaters is left-skewed. The scatterplots and correlations show that all three have some linear relationship with U.S. revenue, but Opening is the strongest (remember Opening has the outlier also). The correlations show also that there is some linear relationship between the explanatory variables as well.
