Find the mean, median, and mode of the data set. Round to the nearest tenth

Test scores on a math test:

88, 89, 65, 62, 83, 63, 84, 63, 74, 64, 71, 82, 66, 88, 79, 60, 86, 63, 93, 99, 60, 85

Mean: 75.8

Median: 76.5

Mode: 63 (it appeared 3 times) To find the mean, add up the values in the data set and then divide by the number of values that you added. To find the median, list the values of the data set in numerical order and identify which value appears in the middle of the list. To find the mode, identify which value in the data set occurs most often.

First arrange the data in ascending order:-

60, 60, 62, 63, 63, 63, 64, 65, 66, 71, 74, 79, 82, 83, 84, 85, 86, 88, 88, 89, 93, 99

The mode is the value which occurs the most Here it is 63

The median is the middle number in the list (or the mean of the 2 middle numbers) = (74+79) / 2 = 76.5

To find the mean add up the total and divide by the total number of data which is 22
