Given σ,the population standard deviation, is unknown, the sequence for the five tests arranged in priority order goes like t test, Grubbs test, peakness test, Dixion test, skewness test.
未知总体标准差σ ,在五种检验法中 ,优劣次序为 :t检验法、格拉布斯检验法、峰度检验法、狄克逊检验法、偏度检验法。
Under the condition that the two tests have same probability of making error of the first kind (seeing true the as the false),the probability for t test to make error of the second kind(seeing the false as the true),is lower,namely t test excels Grubbs test in inspection function.
在犯第一类错误 (将真当假 )的概率相同的情况下 ,t检验法比格拉布斯检验法犯第二类错误 (将假当真 )的概率小 ,即 t检验法的检验功效更
