| 摘 要： | 分层抽样作为现代统计方法中最常用的抽样组织形式，已在实践中受到主管广泛重视，它比纯随机抽样具有更高的抽样精度。本文在介绍分层抽样法的基础上将该方法应用于A企业的B产品的抽样检验中，并取得了较好的效果。产品被滞留在生产车间内的比例由20％批／班次减少为平均5％批／班次，生产秩序明显好转。

| Abstract: | As a common sampling method in modern statistics, stratified sampling attracts much attention in practice. It has higher sampling precision than random sampling. This paper introduces stratified sampling, and applies it to sampling practiceof Product B in Company A, which leads to good results. The proportion of products that are held in workshops is reduced from 20% to 5% lot per class. Also the manufacturing order is obviously improved. |
