How do the mean, median, and mode compare for different distributions?
What will be an ideal response?
Because the mean is the average of the scores, it will be more influenced by extreme scores than the other measures. Thus, for a skewed distribution, the mean will be closest to the extreme scores, followed by the median and the mode, which will be closer to the middle of the distribution. For symmetrical distributions, however, the three measures will provide the same value that is in the middle of the distribution.
