The mean is the only measure of central tendency that takes into account every score in the distribution, including the highest score. Changing the highest score would affect the mean, as it would change the sum of all scores and thus the calculated average. The median and mode, on the other hand, only rely on the middle or most frequent scores in the distribution, respectively, and would not be affected by a change to the highest score.
