In the previous activity, we compared the distributions of the number of wins of teams in two Division I conferences. When comparing distributions using side-by-side boxplots, you can also compare more than two groups. The following image compares the distributions of the number of football game wins of teams in five Division I conferences in the 2014 season.
X axis is labeled "Football Wins 2014." ACC Boxplot: box spans ~6 to ~9; lower line extends from 3 to ~6; uppline extends from ~9 to ~13. Big 10 Boxplot: box spans 5 to 9.5; lower line extends from 3 to 5; upper line extends from 9.5 to 14. Pac 12 Boxplot: box spans ~5 to 10; lower line extends from 2 to ~5; uppline extends from 10 to ~13. SEC boxplot: box spans 7 to 10; lower line extends from 3 to 7; upper line extends from 10 to 12. Con USA Boxplot: box spans 4 to 8; lower line extends from 3 to 4; upper line extends from 8 to ~13.
For this question consider only the ACC and Big 10. Which of the two conferences had a larger percentage of teams with seven or more wins?
ANSWER:
Both conferences had the same percentage of teams with seven or more wins.
Good job! Indeed since 7 is the median of both distributions, both conferences had 50% of their teams with seven of more wins.
