| 摘 要： | 抽样技术正成为我国社会经济统计调查和分析的重要手段。实际中的抽样大多是对有限总体的不重置抽样。指出了以往关于有限总体修正系数证明的局限性，给出了有限总体不重置抽样成数和均值标准差公式的一般性证明，该证明更直接体现了抽样的随机特征。

| Abstract: | Sampling techniques are becoming important means of economic and social statistical surveys and analysis. Most of the pratical samples are drawn from finite populations without replacement. In previous proofs on finite population corrections of standard error in sampling without replacement, all possible sample means are adopted in computing standard error. Thus,the main limitation of these proofs is that the effect of random sampling on the uncertainty of sampling means is not stated directly. In this paper,a general Proof of standard error formulae for sampling proportions and means is given with the characteristics of random sampling being revealed more directly. |
