The mean is more influenced by extreme scores than other measures of central tendency.

Question

Quizplus · Accepted Answer

The mean is calculated by adding up all the scores and dividing by the total number of scores. However, if there are extreme scores, they can greatly affect the overall average. For example, if a group of students scored 90, 85, 80, and 40 on a test, the mean would be 73.75. However, if one student scored 100 instead of 40, the mean would increase to 88.75. This shows how one extreme score can greatly influence the overall mean. Other measures of central tendency, such as the median or mode, are not as influenced by extreme scores.
