补充资料：抽样调查
| 抽样调查 sampling survey 调查研究的主要方法之一。总体按随机原则抽取一定数量的单位作为样本进行调查，并以其结果来推断总体一般情况的工作。主要用于不能或不便进行全面调查而又需要了解总体一般情况的调查研究。抽样调查中抽取样本的方式有：①单纯随机抽样，即在总体中任意抽取一定数量的样本。通常是将总体全部单位编号后用抽签方式进行。②机械随机抽样。即事先将总体按任何一种标志排列或分组，然后按固定顺序和间隔抽取样本。③类型随机抽样(或称分层随机抽样)。即事先有计划地将所有单位划分为不同类型的组别，再在各组中按单纯或机械随机方式抽取样本。④整群随机抽样。即在统计总体中随机每次抽取整群单位作为样本。在实践中，往往根据抽样研究的目的、现象、性质和总体条件来做决定。 |
