Question

Find the mean, median, and modes of the data set: 91, 93, 89, 97, 89, 98, 94,
93. (2 points)

Answer 1

Mean: To find the mean, add up all the numbers and divide by the total number of numbers.
Mean = (91 + 93 + 89 + 97 + 89 + 98 + 94 + 93) / 8 = 744 / 8 = 93

Median: To find the median, first put the numbers in order from least to greatest: 89, 89, 91, 93, 93, 94, 97, 98. Since there are 8 numbers in the data set, the median is the average of the two middle numbers, which in this case are 93 and 93. So, the median is (93 + 93) / 2 = 93.

Modes: The mode is the number that appears most frequently in the data set. In this case, the modes are 89 and 93, as they both appear twice, which is more than any other number in the set.
