Comparison of Mode, Median, and Mean While all three of these measures of Central Tendency describe the middle or center or typical score within a distribution, they are different in many ways.
First, the mode is the crudest measure of central tendency as it is affected by only one score within a distribution -- i.e. the score that occurs most often.
Likewise, the median is affected by only one score -- i.e. the middle score within a distribution.
In marked contrast, the mean is the most sensitive measure of central tendency, as all scores within a distribution affect its magnitude.
