摘要
通过对整群抽样的等概率简单估计法和比率估计法的计算比较，阐述了影响整群抽样的抽样误差的因素，以及各因素之间的相互关系．从而对如何选择合适的估计方法进行了讨论．
This paper puts forword the factors affecting sampling error under the whole group sampling survey by comparing two methods ---equiprobability simple estimation and equiprobability ratio estimation.And it gives out these factors correlativity. Then,the author summarizes how to choose the calculating method with the whole group sampling survey.
