Students watched 5 videos, and rated them on a scale of 1 to 10. While the average score for every video is the same (5.5), the shapes of the ratings distributions were very different! Match the summary description (left) with the shape of the histogram of student ratings (right). For each histogram, the x-axis is the score, and the y-axis is the number of students who gave it that score. These axes are intentionally unlabeled - focusing on the shape is what matters here!

Most of the students were fine with the video, but a couple of them gave it an unusually low rating.

1

A

Histogram with 6 columns whose respective heights from left to right are 1, 1, 3, 3, 1, 1

Most of the students were okay with the video, but a couple students gave it an unusually high rating.

2

B

histogram with 10 bars equal in height based on contrived data

Students tended to give the video an average rating, and they weren’t likely to stray far from the average.

3

C

Histogram with 9 bars whose heights from left to right are 0,1,3,3,1,0,0,1,1

Students either really liked or really disliked the video.

4

D

Histogram with 9 bars whose heights from left to right are 0,1,1,0,0,1,3,3,1

Reactions to the video were all over the place: high ratings and low ratings and inbetween ratings were all equally likely.

5

E

Histogram with 11 bars whose heights from left to right are 0,2,2,1,0,0,0,0,1,2,2
