What is median?
Median: The middle value of a distribution, so that half the probability lies at or below it and half at or above. Unlike the mean, it is not pulled around by extreme values, which makes it a robust measure of typical size.
Median: an example
Salaries of 20k, 25k, 30k, 32k and 400k have a median of 30k, although their mean is far higher.
