Cluster sampling整群抽样和Stratified random sampling分层抽样典型区别在于:在整群抽样Cluster sampling中,只有选定的cluster里面的个体才有机会成为样本a whole cluster is regarded as a sampling unit and only sampled clusters are included,没有被选中的cluster是不会有机会成为样本的。而在Stratified random sampling...

整群抽样Cluster sampling与分层抽样Stratified random sampling两种抽样方法，各有特点与应用。整群抽样中，整个集群被视为样本单位，仅选定的集群纳入样本，未被选中的集群无法成为样本。相反，分层抽样则将总体分为多个层级，每个层级内随机抽取样本。在整群抽样中，首先将总体划分为多个集群，每个集群都是...
The cluster method comes with a number of advantages over simple random sampling and stratified sampling. The advantages include: 1. Requires fewer resources Since cluster sampling selects only certain groups from the entire population, the method requires fewer resources for the sampling process. Ther...

You can also continue this procedure, taking progressively smaller and smaller random samples, which is usually called multistage sampling. You should use this method when it is infeasible or too expensive to test the entire cluster. Example: Multistage samplingInstead of collecting data from every ...
1.simple random sample(简单随机抽样):在简单随机抽样中,总体所有成员被选为样本的概率是相等的.2.stratified sampling(分成抽样):将总体分成不同的子群,然后对所有的子群进行抽样.3.systematic sampling(系统抽样):首先将总体中各单位按一定顺序排列,根据样本容量要求确定抽选间隔,然后随机确定起点,每隔一定的间隔抽取...
