- 0,5-fractile of a probability distribution
- for
*n*real values not necessarily different from each other, real number such that the number of values less than it is equal to the number of values greater than it

Note 1 to entry: If *n* is odd, the median is the value of rank $(n+1)/2$ when the values are arranged in increasing order. If *n* is even, the median may be any number between the values of rank $n/2$ and $(n/2+1)$, usually the arithmetic mean of these two values.
