| 摘 要： | 对于分层抽样和整群抽样，当群体间的差异、群内个体间差异均不显著时，其估计精度往往都很差．针对这一缺陷，提出了一种辅以分层抽样样本的整群抽样方案，得到了总体均值的估计量，以及这一估计量的一些良好性质．这些结果表明，与单一的整群抽样、单一的分层抽样估计量相比，这种抽样设计的估计量具有更高的精度

| Abstract: | For stratified and cluster sampling with inappreciable differences, estimate precision becomes poor. The estimation of population mean is obtained using a cluster sampling method with supplementary stratified sample. These results show that the present approach is more efficient than the cluster or stratified sampling approach had it been applied individually. |
