CHI-SQUARE TEST Adapted by Anne F. Maben from "Statistics for the Social Sciences" by Vicki Sharp The chi-square (I) test is used to determine whether there is a significant difference between the expected frequencies and the observed frequencies in one or more categories. Do the ...
卡方检验(Chi-square Test),也称卡方拟合优度检验(Chi-square Goodness-of-Fit Test),用于检验样本数据是否与某种概率分布的理论数值相符合,进而推断样本数据是否来自于该分布的样本问题。例如,抽奖球编号0至9,根据出现的数字概率是否均匀,即0至9的出现概率是否为1/10。 首要步骤是给出零假设:总体X服从某种分布,...
