The mean is calculated by adding all the scores together and dividing by the number of scores: (97 + 89 + 85 + 85 + 97 + 99) / 6 = 552 / 6 = 92. The median, which is the middle value when the scores are arranged in order, is 92 (since the sequence sorted is 85, 85, 89, 97, 97, 99, the median is the average of the middle two numbers, 89 and 97, which is 93). The mode, which is the most frequently occurring score(s), is both 85 and 97, as they each appear twice.
