Question

Mary's test grades were 78, 0, 85, 84, 84, and 88. Mary made up the missing test which changed her second test score from 0 to a 93. Which measure(s) of central tendency are affected by this change?

mean

median

mode

mean and median

Answer 1

It's mean and median. The mean is the sum of the numbers and the median is the middle test score so those two would change. The mode wouldn't change because it is the numbers which occur most frequently which is 84 so the score of 93 wouldn't change that.

Answer 4

Coach Ralph wants to compare the number of practice hours logged by members of his team for the month with the number of practice hours logged by the members of the league champion team for the month. He creates box-and-whisker plots of the number of hours each member on his team practiced this month versus the number of hours each member of league champion team practiced for the month. Which statement makes sense based on the plots?



Since the maximums are the same, Ralph's team members practice at least as many hours as the league champions.

There are 16 players on Ralph's team.

Half of the league champions practice less than everyone on Ralph's team.

Ralph's team has hours that are more unpredictable than the overall league.
