一般来说，尺寸大的单位比尺寸小的单位包含更多的辅助信息。因此，当样本来自不同大小的子组或单位时采样的概率相同，从大组中选择成员的几率小于从小组中选择成员的几率尽管这里从大组中选择成员的几率大于从小组中选择成员的几率。也就是说，很明显，选择一个单位的概率与它的大小成正比。本文的目的是提出一种选择与大小成概率比例的样本的方法。该方法使用相对频率来选择与大小成概率比例的样本。与累积总量法和拉希里法相比，该方法耗时短，易于应用。关键词：PPS抽样，累积总量法，Lahiri法，累积相对频率法。
Generally in the sense that, the unit with large size contain more ancillary information than the unit with smaller size. So when samples from different sized subgroups or units are used and sampling is taken with the same probability, the chances of selecting a member from a large group are less than selecting a member from a smaller group although here the chances of selecting a member from a large group will be greater than selecting a member from a smaller group. That is it is clear that, the probability of selecting a unit is positively proportional to its size. The aim of this paper is to propose a method of selecting samples in probability proportional to size. This method uses relative frequency to select samples in probability proportional to size. Comparatively it takes less time and easy to apply than Cumulative Total Method and Lahiri’s Method. Keywords: Probability Proportional to Size (PPS) Sampling, Cumulative Total Method, Lahiri’s Method, Cumulative Relative Frequency Method.
