评估了异常值对反应时间分析的影响。第一部分评估了最小化异常值对方差分析（ANOVA）影响的不同方法的力量，并提出了关于使用转换和截止点的建议。第二部分考察了异常值和截止值对位置、分布和形状的不同度量的影响，并使用定量示例得出结论，鲁棒度量受异常值和截止值的影响远小于基于矩的度量。第三部分考察了拟合显式分布函数作为恢复均值和标准差的一种方式，并得出结论，除非拟合分布函数用作分布形状的模型，否则该方法可能不值得常规使用。
The effect of outliers on reaction time analyses is evaluated. The first section assesses the power of different methods of minimizing the effect of outliers on analysis of variance (ANOVA) and makes recommendations about the use of transformations and cutoffs. The second section examines the effect of outliers and cutoffs on different measures of location, spread, and shape and concludes using quantitative examples that robust measures are much less affected by outliers and cutoffs than measures based on moments. The third section examines fitting explicit distribution functions as a way of recovering means and standard deviations and concludes that unless fitting the distribution function is used as a model of distribution shape, the method is probably not worth routine use.
