De nition: The median of X is the value xfor which P(X x) = 0:5, i.e. the value of xsuch that P(X X) = P(X x). In other words, X has equal probability of being above or below the median, and each probability is therefore 1/2. In terms of the cdf F(x) = P(X x), we can equivalently de ne the median as the value xsatisfying F(x) = 0:5.
