A class of students took five different exams this year, and each distribution of their scores has been plotted in one of the five box plots below.

Match the summary description (left) with the shape of the box plot of student scores (right).

1

A

Most students did pretty well on this exam, but there were some mediocre scores and a handful of very low scores.

a symmetrical box plot whose whiskers span a range about double the size of either of the boxes in the middle

2

B

This exam featured one question worth a lot of points that many of the students got completely right, while many others got it completely wrong. Nobody actually got the "average" score.

a box plot where the left whisker falls directly along the left side of the box, the box representing the second quartile is twice as wide as the box representing the third quartile, and the whisker representing the fourth quartile spans about six times the range of the second quartile

3

C

A lot of students did poorly on this exam. Relatively few did just OK. Still, a bunch of students who really knew what they were doing completely aced it.

a box plot with a long left whisker, 2 equal-size boxes that each span about 1/3 the distance of the left whisker, and a right whisker whose span is about 1/4 the size of either of the boxes.

4

D

Performance on this exam resulted in a classic "bell curve" shape: most students performed close to the average and scores far from the average in either direction were increasingly unlikely.

a box plot with short whiskers. The box representing the second quartile is about 1/3 the size of the box representing the third quartile.

5

E

This was a hard exam. Most students did poorly, with scores tapering to the point where hardly anyone got an A.
