Mean: (91 + 93 + 89 + 97 + 89 + 98 + 94 + 93) / 8 = 92

To find the median, first arrange the data set in numerical order:
89, 89, 91, 93, 93, 94, 97, 98
Since there are 8 numbers, the median is the average of the 4th and 5th numbers: (93 + 94) / 2 = 93.5

The mode(s) is/are the number(s) that appear most frequently in the data set.
In this case, the modes are 89 and 93 as they each occur twice in the data set.
