※ 引述《gsuper (绿色苏打心)》之铭言： : ※ 引述《binchung (ideal)》之铭言： : : I was not clear in my previous post, so I made clear in this one. : : To be precise, first consider each subject has a rank. : : For example, the first categories have 30+45=75 subjects, so the ranks : : are 1,2,...,75. Then you can calculate the midrank for the first group. : 所以您的意思是指 : 将他的 "非常满意" "满意" "普通" "不满意" "非常不满意" : 切割成5次 two samples 的 rank 统计来计算 : 总共做5次无母数的检定 : 是这样的意思嘛? No, I mean you can compute the midrank for the first group for each category and do the weighted sum according to the number of subjects. Please check Wilcoxson midrank test in 'nonparametric statistics: statistics methods based on ranks' written by E.L. Lehmann. : ------------------------------------------------------ : 其实我满不认同这样的作法 : 如果这样做就可以 : 那ANOVA根本不需要存在 : 只需要作 : C n 取 2 次 : bonferroni t 或是 adjust DMRT 不就好了 : 应该有更简单的方法才对 --
