Baseball coaches use a radar gun to measure the speed of pitcher’s fastball. They also record outcomes such as hits and strikeouts. The scatterplot below shows the relationship between the average speed of a fastball and the average number of strikeouts per nine innings for each pitcher on the Bulldogs, based on the past season.


Do you think there is a pattern? Describe the association between speed and the number of strikeouts.

There appears to be a moderately strong, positive, but nonlinear (curved) association between speed and number of strikeouts. Pitchers with higher speeds tend to have more strikeouts. There
is one point that doesn’t fit the pattern. One pitcher had more strikeouts on average than his average speed would typically indicate.
