Mean: (91 + 93 + 89 + 97 + 89 + 98 + 94 + 93) / 8 = 92.125
Median: Arranging the data set in order, we have: 89, 89, 91, 93, 93, 94, 97, 98. The median is the average of the two middle values, which are 93 and 93. So, the median is (93 + 93) / 2 = 93.
Modes: The modes are the values that appear most frequently in the data set. In this case, both 89 and 93 appear twice, which makes them both modes. So, the first mode is 89 and the second mode is 93.
