Median of a distribution is the value of...

Median of a distribution is the value of the variable which divides it into equal parts . In case of individual observations `x_1,x_2` .. `x_n`, if the number of observations is odd, then median is the value of `((n+1)/2)` th observation when the observations have been arranged in ascending or descending order of magnitude. In case of even number of observations median is the A.M. of the values of `(n/2)`th and `(n/2+1)` th observations, arranged in ascending or descending order of magnitude . The mode of distribution is that value of the variable for which the frequency is maximum .
