me·di·an (meґde-ən) [L. medianus] 1. situated in the median plane or in the midline of a body or structure. 2. any value that divides the probability distribution 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.
