Mean:
Add up all the numbers and divide by the total number of numbers:
(91 + 93 + 89 + 97 + 89 + 98 + 94 + 93) ÷ 8 = 92
The mean is 92.
Median:
Arrange the numbers in order from smallest to largest:
89, 89, 91, 93, 93, 94, 97, 98
There are 8 numbers, so the median is the average of the two middle numbers:
(93 + 94) ÷ 2 = 93.5
The median is 93.5.
Mode:
The mode is the number(s) that appear the most frequently in the data set.
In this case, both 89 and 93 appear twice, so the modes are 89 and 93.
Find the mean, median, and modes of the data set: 91, 93, 89, 97, 89, 98, 94, 93
