Question

Find the mean, median, and modes of the data set: 91,93,89,97,89,98,94,93

Answer 1

To find the mean, add up all the numbers in the data set and then divide by the total count of numbers:

91 + 93 + 89 + 97 + 89 + 98 + 94 + 93 = 744
Mean = 744 / 8 = 93

To find the median, first put the numbers in numerical order:

89, 89, 91, 93, 93, 94, 97, 98

Since there are an even number of values, the median will be the average of the two middle numbers:

(93 + 94) / 2 = 93.5

To find the modes, find the number(s) in the data set that appears most frequently. In this case, both 89 and 93 each appear twice, making them the modes of the data set.
