Verbal SAT as a Predictor of GPA A scatterplot with regression line is shown below for a regression model using Verbal SAT score, VerbalSAT, to predict grade point average in college, GPA, using the data in StudentSurvey. We also show computer output of the regression analysis below.

NBA Players: Correlation Matrix The dataset NBAPIayersZOlS contains information on many variables for players in the NBA (National Basketball Association) during the 201415 season. The dataset includes information for all players who averaged more than 24 minutes per game (n = 182) and 25 variables, includingAge, Points (number of points for the season per game), FTPct (free throw shooting percentage), Rebounds (number of rebounds for the season), and Steals (number of steals for the season). A correlation matrix for these five variables is shown. A correlation matrix allows us to see lots of correlations at once, between many pairs of variables. For any pair of variables (indicated by the row and the column), we are given two values: the correlation as the top number and the pvalue for a twotail test of the correlation right beneath it.
