摘要
目的：研究县乡级计划免疫接种率调查的抽样方法。方法：在充分利用计划免疫以往信息的基础上，采用整群抽样与二阶段整群抽样方法来实现。结果：建立的方法经计算机模拟与现场验证令人满意。结论：在９５％可信限与±１０％误差条件下，通常对乡级抽取２～３个行政村，对县级抽取６～８个行政村调查，即可反映计划免疫接种率状态。
Objective:our aim in this paper is to investigate EPI inoculation rate in townships and countries.Methods:after we utilized the standard deviation obtained from previous data(information)to choose the sample size according to its difference,we used the cluster sample method and two-stage cluster-sample method to investigate children′s inoculation rate.Result:the result of experiment is satisfactory by computer imitation and accords with actual condition.Conclusion:with the limit error within±10%and confidence limit in 95%,we usually take the sample in 2～3 villages in the same township or 6～8 villages in the same country.
