The median and mean of a set of data can often times be quite different from one another. One example of this is household income in the United States. According to the U.S. Census Bureau’s 2014 Annual Social and Economic Supplement, mean household income in 2014 was $72, 641, while median household income was $51,939.
Why are the mean and median so different in this case? Find another example of a statistic in which the mean and median values would be expected to be quite different and explain the difference.
