Median

median

(Science: statistics) Any value that divides the probability of a random variable in half, i.e. The probability of observing a value above the median and the probability of observing a value below the median are both less than or equal to one half.

For a finite population or sample, the median is the middle value of an odd number of values (arranged in ascending order) or any value between the two middle values of an even number of values, in the latter case it is conventional to use the average of the two middle values.

Origin: L. Medianus
