WebOrder Statistics In a set S of totally ordered values, the kth order statistic is the kth smallest value in the set. The 0th order statistic is the minimum value. The 1st order statistic is the second-smallest value. The (n – 1)st order statistic is the maximum value. In the static case (when the data set is given to you in advance), algorithms like quickselect and median-of-
