| 摘 要： | 对抽样知识的理解是统计素养的基础，而抽样方法是抽样知识的重要组成部分．中学生在没有学抽样知识前就表现出了统计学上常用的几种抽样方法萌芽．总体上，他们在抽样过程中对随机性缺乏认识，认识不到随机样本的统计公平性，而更相信分层抽样，而且不同年级、不同层次水平的学生对抽样知识的认识也存在差异。

| Abstract: | An understanding of sampling was fundamental to statistical literacy and sampling methods were the key of sampling. A questionnaire was carried out to investigate middle school students sampling methods. The main finding was that before learning sampling methods systematically the middle school students had the primitively ideas of the sampling methods. In general students often did not recognize the statistical fairness of random samples and more believed stratified sampling and students?sample selections were different according to their grade and achievement. |
