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 and inference.
Important special cases of the order statistics are the minimum and maximum value of a sample, and (with some qualifications discussed below) the sample median and other sample quantiles.
When using probability theory to analyze order statistics of random samples from a continuous distribution, the cumulative distribution function is used to reduce the analysis to the case of order statistics of the uniform distribution.

Famous quotes containing the word order:
“Man is clearly made to think. It is his whole dignity and his whole merit; and his whole duty is to think as he ought. And the order of thought is to begin with ourselves, and with our Author and our end.”
—Blaise Pascal (1623–1662)
