The mean score of the class is: 84.5

The median score of the class is: 87

The modal score of the class is: 84.5

Mean = sum of all data points divided by the number of data points.

Median = the middle value of the ordered data.

Mode = the data point with the highest frequency or that appears the most.

Thus:

Arrange the data in ordered form:

60, 70, 75, 80, 80, 80, 80, 80, 80, 85, 87, 87, 87, 88, 90, 90, 90, 91, 92, 93, 95, 98

Mean = 1858/22

Mean = 84.5

Median = (87 + 87)/2 = 87

Mode = 80

Thus:

The mean score of the class is: 84.5

The median score of the class is: 87

The modal score of the class is: 84.5
