We can now calculate the p-value for the chi-square test statistic by using a formula of form =CHISQ.TEST(Obs,Exp,df) whereObsis the 3 × 3 array of observed values,Exp= the 3 × 3 array of expected values anddf= (row count – 1) (column count – 1) = 2 ∙ 2 = 4. Sin...
(4)确定自由度,(6-1)×(2-1)=5;选择显著水平α=0.05。 (5)利用Excel提供的CHIINV函数求临界值,在D9单元格中键入“=CHIINV(0.05,5)”按回车键,得临界值11.07。 (6)比较临界值和统计量,11.07>2.3,即临界值大于统计量,故差异不显著,接受H0。 2.应用实例2——独立性检验 卡方独立性检验是用来检验两个属...
皮尔逊χ²检验(Pearson's Chi-squared Test),也称为卡方检验,是由英国统计学家卡尔·皮尔逊(Karl Pearson)在19世纪末提出的。它是统计学中最常用的一种非参数检验方法,最初设计用于评估观察频数与期望频数之间是否存在显著差异,常用于推断分类变量间的独立性或拟合优度检验。 原理与定义 皮尔逊χ²检验的基本思...
