Median ( for odd number of observations)

Description

In statistics and probability theory, the median is the numerical value separating the higher half of a data sample, a population, or a probability distribution, from the lower half. The median of a finite list of numbers can be found by arranging all the observations from lowest value to highest value and picking the middle one, for odd number of observations and the mean of the two middle values, for even number of observations. ( e.g. for five numbers in order the median is the third term).
