数据的统计处理和解释. 第6部分: 统计容忍区间的测定

[中文适用范围]： ISO 16269 的这一部分描述了建立统计公差区间的程序，其中至少包括具有指定置信水平的指定比例的总体。 提供单侧和两侧统计容差区间，单侧区间具有上限或下限，而两侧区间具有上限和下限。 提供了两种方法，一种是参数方法，适用于所研究的特性具有正态分布的情况；另一种是无分布方法，适用于除了连续分布以外对分布一无所知的情况。 还有一种程序可以为多个具有共同未知方差的正态样本建立双边统计公差区间。 [外文原描述]： ISO 16269-6:2013 describes procedures for establishing statistical tolerance intervals that include at least a specified proportion of the population with a specified confidence level. Both one-sided and two-sided statistical tolerance intervals are provided, a one‑sided interval having either an upper or a lower limit while a two-sided interval has both upper and lower limits. Two methods are provided, a parametric method for the case where the characteristic being studied has a normal distribution and a distribution‑free method for the case where nothing is known about the distribution except that it is continuous. There is also a procedure for the establishment of two‑sided statistical tolerance intervals for more than one normal sample with common unknown variance.
