摘要
分层随机抽样是近代统计调查方法中最重要、最常用的方法之一。在分层抽样中,样本量在各层的不同分配方法会对估计量的精度产生一定的影响。本文立足于分层随机抽样在实践中的重要性以及样本容量分配的重要意义,从分析影响样本容量的因素入手,讨论实践中分层抽样样本量分配的方法体系并进行比较评价,得出各种方法的适用性。
Stratified random sampling （STS） is one of the important ways widely used in modem statistical surveys. In STS, the different ways of sample size allocation in different strata can influence the precision of the estimator. Based on the importance of STS in practice and the significance of sample size allocation, this article starts with the analysis of the influential factors upon sample size, and with a comparison and evaluation of the methodology of stratified sampling size allocation in practice, discovers the applicability of various methods.
