Re: [問題] 一題統計問題
※ 引述《gsuper (綠色蘇打心)》之銘言：
: ※ 引述《binchung (ideal)》之銘言：
: : 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
: 將他的 "非常滿意" "滿意" "普通" "不滿意" "非常不滿意"
: 切割成5次 two samples 的 rank 統計來計算
: 總共做5次無母數的檢定
: 是這樣的意思嘛?
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.

: 其實我滿不認同這樣的作法
: 如果這樣做就可以
: 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
: 應該有更簡單的方法才對
