The mean is calculated by adding up all the scores and dividing by the number of scores. Thus, if there is an extreme score (very high or very low) it can greatly affect the overall calculation of the mean. For example, if a group of 10 students took a test and 9 of them scored around 80%, but one student scored 10%, it would greatly bring down the mean score. Therefore, the mean is the measure of central tendency that is most affected by extreme scores.
