A basketball coach was puzzled because some players improved much faster than others. Emek and Luna collected each player's weekly practice hours and shooting accuracy, then plotted every pair of values on a scatterplot. Most points showed a positive relationship: players who practiced more hours generally had higher shooting accuracy. However, a few unusual points stood away from the main pattern. After discussing those players individually, the coach adjusted the training program to better match each athlete's needs. Over the following weeks, the team trained more effectively and showed steady improvement.
