Students watched 5 videos, and rated them on a scale of 1 to 10. The average score for every video is the same (5.5).

Match the summary description (left) with the shape of the histogram of student ratings (right).

  • The x-axis shows the score, and the y-axis shows the number of students who gave it that score.

  • These axes are intentionally unlabeled - the shapes of the ratings distributions were very different! And that’s the focus 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
