The box plot below shows the scores on last week’s
test for 10 randomly selected students from each of Mr.
Brenner’s two mathematics classes.

Which statement about the performance of the
students in the two classes is best supported by
the data from these samples?
A The two classes performed equally well because the range
B
Which conclusion is best supported by the data?
of each class is the same.
A
The range of the Lincoln School data was 40 greater
than the range of the Adams School data.
The two classes performed equally well because the
greatest score in each class is the same.
B
The median numbers of cans collected at both
schools was approximately the same.
C
Adams School had the least and the greatest number
of cans recycled per week.
D
Lincoln School recycled more can per week than
Adams School for more than half of the week in the
20-week period.
A random sample of the numbers of miles that
two people drove each day last month is shown
below.
C The students in Class Y generally performed better than
the students in Class X because most students in Class Y
had a score greater than 70.
D The students in Class Y generally performed better than
the students in Class X because the median of Class Y is
greater than that of Class X.

Two schools used can recycling as a school project
last year. They both recorded the number of cans
recycled per week for 20 weeks. The data is
displayed in the box-and-whisker plots below.

A
Give the survey to every student in the eighth grade.
B
Give the survey to every student taking a science
class after lunch.
C
Give the survey to every student who walks or rides
a bicycle to school.
A
William has the greater median and mean, so he generally
drove farther last month than Martina.
D
Give the survey to every third student entering the
building in the morning.
B
Martina has the greater median and mean, so she
generally drove farther last month than William.
C
William has the greater median and Martina has the
greater mean, so William generally drove farther last
month than Martina.
D
Martina has the greater median and William has the
greater mean, so Martina generally drove farther last
month than William.

she read 16 pages. For each of the next 3 days, the number of pages she
read increased by 50% over the number of pages she read on the previous
day. Greg read the same history assignment, but he read an equal number
of pages per day from Monday through Friday. How many pages did Greg
