抽样统计是什么

ehouyong

抽样统计(~pling
statisties)按照随机原则从资
源开发利用现象的总体中抽取一部分个体进行统计调查，用
调查的个体样本推断总体的某些指标的一种非全面调查。抽
样统计设计有简单随机抽样、分层抽样、系统抽样、分群抽
样、多级抽样等方法。
在抽样统计中有时不能以自然个体为单位，而要按实际
需要和使用方便把这些自然个体划分为若干单元，抽样时把
每个单元看作一个个体，称为抽样单元。比如可在地图上划
分许多格，每格代表一个抽样单元，格的大小也可不同。构
成总体的全体抽样单元的一个总的描述叫做抽样框，一幅地
图也可为抽样框。
出于对费用和时间的考虑，抽样统计已逐渐作为一个重
要的统计方法。这是因为，普查的工作量太大，往往为人力、
财力、时间所限，在实施过程中易出现人为的误差;经验表
明，有时一个精心设计的抽样方案，其实施效果甚至可以胜
过普查。

couple pair brace yokeThese nouns denote two individuals of the same kind together. 《SKW》 Coupledoes not necessarily imply more than association:
