Question 8

You are an assistant coach in the Australian Football League. In your role, you evaluate and assess a specific group of players for your team after each game. These evaluations are used to select players for upcoming games. The head coach has decided that the team needs to focus on more strongly rewarding players for their effort during each game.

For each player in your team, you have large amounts of historical performance data. You have decided to examine how far each player runs per game. While not perfect, this is a reasonable proxy for each players' in-game effort level. You want to use this measure to say whether or not a player worked hard enough in a game. This entails making within- and between player performance comparisons.

The running distance per game of three players in your team is plotted below. This data set covers the team's five most-recent games.
