  "body": "\n## Summary\n\nThe $k$-th order statistic of a sample is its $k$-th smallest value.\nThe minimum, the maximum, the median and the sample quantiles are order statistics or simple functions of them.\nThey are the basis of many nonparametric and robust methods, and their distributions have explicit formulas for i.i.d. samples.\n\n## Explanations\n\n### L1 human\n\nWrite the numbers of a sample in increasing order.\nThe first number in the sorted list is the first order statistic, the second is the second, and so on.\nFor the sample $5, 1, 3$, the sorted list is $1, 3, 5$, so the order statistics are $1$, $3$ and $5$.\nThe middle one, $3$, is the sample median.\n",
