When p is a rational number (with the exception of p = 1/2 \ and n odd) the median is unique. [ 14 ] When p = 1 2 {\displaystyle p={\frac {1}{2}}} and n is odd, any number m in the interval 1 2 ( n − 1 ) ≤ m ≤ 1 2 ( n + 1 ) {\displaystyle {\frac {1}{2}}{\bigl (}n-1{\bigr )}\leq m\leq {\frac {1}{2}}{\bigl (}n+1{\bigr )}} is a median of the ...
