... The Median is the center number of a set of numbers. The pth percentile (p between 0 and 100) of a set of numbers is a number with the properties that at least p% of the numbers are less than or equal to the pth percentile and at least (1-p)% of the numbers are greater than or equal to the pth perce ...
