Answer 1

The median age of the players on Team A is less than the median age of the players on B.

• Count to the middle number on each. Median(A) = 18, Median(B) = 19.

The mean age of the players on Team A is less than the mean age of the players on B.

• The mean is the average. Mean(A) = 394/22 = 17.9, Mean(B) = 413/22 = 18.7

The IQR for the age of the players on Team A is less than the IQR for the age of the players on B.

• Take the median of the upper half, and the median of the lower half.
• Q1(A) = 17, Q1(B) = 16.
• Q3(A) = 19, Q3(B) = 21.
• IQR(A) = 19-17 = 2, IQR(B) = 5.

The first quartile of players' age on Team A is greater than the first quartile of players' age on Team B.

• Q1(A) = 17, Q1(B) = 16.
