Then the same for minimal elements. There are about N possible medians, sorting takes O(N*lgN), on every iteration you need to compute up to N means, you can do it in O(N). Medians are less sensitive to extreme scores and are probably a better indicator generally of where the middle of the class is achieving, especially for smaller sample sizes.
