Ordered statistics
WebOrder statistics are defined for k = 1,...,n, so k ≥ 1 as desired in (2). The equation (3) simplifies if F is the U[0,1] distribution function, F(x) = 0 for x < 0, F(x) = x for 0 ≤ x ≤ 1, and … WebOrder statistics play an important role in educational statistics. In many statistical analyses, the information from a random sample is utilized through the ordered values of the sample. At the beginning of the course ‘nonparametric statistics’ the students face the nontrivial operation of ordering of a random sample.

The first order statistic (or smallest order statistic) is always the minimum of the sample, that is, where, following a common convention, we use upper-case letters to refer to random variables, and lower-case letters (as above) to refer to their actual observed values. See more In statistics, the kth order statistic of a statistical sample is equal to its kth-smallest value. Together with rank statistics, order statistics are among the most fundamental tools in non-parametric statistics See more For example, suppose that four numbers are observed or recorded, resulting in a sample of size 4.
