Abstract

Many NCES publications present data that are based on representative samples and thus are subject to sampling variability. In these cases, tests for statistical significance take both the study design and the number of comparisons into account. NCES publications only discuss differences that are significant at the 95 percent confidence level or higher. Because of variations in study design, differences of roughly the same magnitude can be statistically significant in some cases but not in others. In addition, results from surveys are subject to nonsampling errors. In the design, conduct, and data processing of NCES surveys, efforts are made to minimize the effects of nonsampling errors, such as item nonresponse, measurement error, data processing error, and other systematic error.
来自NCES的说明。
许多NCES出版物所提供的数据是基于代表性样本的,因此受到抽样变异性的影响。在这些情况下,统计显著性检验既要考虑研究设计,也要考虑比较次数。NCES出版物只讨论在95%置信度或更高水平上显著的差异。由于研究设计的差异,大致相同幅度的差异在某些情况下可能具有统计学意义,但在其他情况下则不具有统计学意义。此外,调查结果会受到非抽样误差的影响。在NCES调查的设计、实施和数据处理过程中,努力将非抽样误差的影响降到最低,如项目无反应、测量误差、数据处理误差和其他系统误差。
