排序集抽样是一种可用于提高均值估计器精度的方法。在对感兴趣的变量进行测量比排序困难得多的情况下，它是有用的。然而，即使排序困难，但有一个容易排序的伴随变量可用，那么它可以用来对原始变量进行“判断排序”。估计器精度的增加量取决于这两个变量之间的相关性。
Ranked set sampling is a procedure which may be used to improve the precision of the estimator of the mean. It is useful in cases where the variable of interest is much more difficult to measure than to order. However, even if ordering is difficult, but there is an easily ranked concomitant variable available, then it may be used to “judgment order” the original variable. The amount of increase in the precision of the estimator is dependent upon the correlation between the 2 variables.
