A teacher surveyed her class after they had taken a vocabulary test. Eighteen of the students claimed they had studied at least one hour for the test. The remaining twelve students admitted that they had not studied for the test at all. The test results (expressed as a percent) for the two groups are shown below.
Studied: 87, 100, 94, 79, 92, 100, 95, 83, 89, 99, 100, 91, 89, 95, 100, 93, 96, 83
Did Not Study: 82, 72, 45, 91, 58, 83, 65, 87, 90, 77, 73, 89
The mean of the group that studied is about 16 points A. Lower B. Higher
than the mean of the group that did not study.
The MAD of the group that did not study is about A. Half B. Twice
as much as the MAD of the group that did study.
There is more variation in the scores of the group that A. did not study B. Studied
