The National Collegiate Athletic Association (NCAA) is divided into three divisions (Division I, II, and III), based roughly on school size. Each division is made up of several conferences for regional league play.
The side-by-side boxplots below compare the distributions of football game wins of teams in two Division I conferences: the Big 10 and SEC (Southeastern Conference) during the 2014 season. (For example, note that the median of the SEC distribution is 8. This means that 50% of the teams in the SEC division had more than eight wins and 50% of the teams had less than eight wins).
X axis is labeled "Football Wins 2014." Big 10 Boxplot: box spans 5 to 9.5; lower line extends from 3 to 5; upper line extends from 9.5 to 14. SEC boxplot: box spans 7 to 10; lower line extends from 3 to 7; upper line extends from 10 to 12.
Which conference has a greater percentage of teams with eight or more wins?
ANSWER:
The SEC
Good Job. Indeed, the SEC has a median of eight wins, which means 50% of the teams had eight or more wins. The Big 10 conference has a median of 7 wins, which means that 50% of the teams had seven or more wins, and so less than 50% of the teams had eight or more wins.
