Mean: (91+93+89+97+89+98+94+93) / 8 = 92.375
Median: Arranging the data in ascending order: 89, 89, 91, 93, 93, 94, 97, 98. The median is the average of the two middle numbers, so (93+94)/2 = 93.5.
Modes: The modes are the numbers that appear most frequently in the data set. In this case, both 89 and 93 appear twice, so they are both modes.

To find the mean, you add up all the numbers and then divide by how many numbers there are. So for this data set, you add: 91+93+89+97+89+98+94+93 = 744. Then you divide 744 by 8, because there are 8 numbers in the data set. So the mean is 744/8 = 92.375.
To find the median, you first put the numbers in order from smallest to largest: 89, 89, 91, 93, 93, 94, 97, 98. Then you find the middle number, which is the one in the middle when the numbers are in order. Since there are 8 numbers, the two middle numbers are 93 and 94. To find the median, you add those two numbers together and divide by 2: (93+94)/2 = 93.5.
The modes are the numbers that appear most often in the data set. In this case, both 89 and 93 appear twice, so they are both modes.
