Two measures of a baseball player's effectiveness as a hitter are the number of hits he makes in a season and the number of times he “bats in" a run (knows as "Runs Batted In" or RBIS). Can we predict a batter’s RBIS from his hits? Below is numerical and graphical output from a computer regression of RBIS on Hits for 12 randomly selected Major League Baseball batters in 2017.
