• How many classrooms are on the first floor?

The dot plot shows how many points certain students scored on a homework assignment. What is the interquartile range (IQR) of the data set shown?

The data displayed represents the distribution of student absences for the school year. Which statement best describes the distribution of the data?

• The distribution of the data is clustered between 10 and 15.

• The distribution of the data is skewed right.

• The distribution of the data is skewed left.

• The distribution of the data has a gap between 1 and 3.

Which quantitative measures describe how data is summarized?

• interquartile range

• mode

• mean absolute deviation

• median

• mean

A coach compared the heights of the players on two different teams. The data set is shown in the table below. Based on these data, which statement is true?

• The mean height of the players on Team B is greater than the mean height of the players on Team A.

• The mean height of the players on Team A is greater than the height of the players on Team B.

• The median height of the players on Team B is greater than the median height of the players on Team A.

• The median height of the players on Team A is greater than the median height of the players on Team B.

Which statement is true?

• The freshman class has LESSER MEAN number of cans donated than the sophomore class.

• The freshman class has THE SAME MEDIAN number of cans donated than the sophomore class.

• The freshman class has GREATER MEAN number of cans donated than the sophomore class.

• The freshman class has GREATER MEDIAN number of cans donated than the sophomore class.

Answer explanation

The "MIDDLE" for the freshman class is further to the left, so the freshman MEDIAN IS LESS than the sophomore median.
