Definition:
  1. 0,5-fractile of a probability distribution
  2. 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 MathType@MTEF@5@5@+= feaagKart1ev2aqatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbbjxAHX garuavP1wzZbItLDhis9wBH5garmWu51MyVXgarqqtubsr4rNCHbGe aGqipG0dh9qqWrVepG0dbbL8F4rqqrVepeea0xe9LqFf0xc9q8qqaq Fn0lXdHiVcFbIOFHK8Feea0dXdar=Jb9hs0dXdHuk9fr=xfr=xfrpe WZqaaiqaciWacmGadaGadeaabaGaaqaaaOqaaiaacIcacaWGUbGaey 4kaSscLbqacaaIXaGccaGGPaGaai4laKqzaeGaaGOmaaaa@3B92@ when the values are arranged in increasing order.
