标题[问题] 统计 无母数 还是 ANOVA变异数分析??
时间Fri Feb 10 16:51:30 2012
题目如下
consider the problem of comparing the reaction times of subjects under the
influence of three different drugs.
each of the three drugs is administered to the same subject with suitable
time lags between the three does.
the data is shown as follow
subject 1 2 3 4 5 6
drug a 1.21 1.63 1.42 2.43 1.16 1.94
drug b 1.48 1.85 2.06 1.98 1.27 2.44
drug c 1.56 2.01 1.7 2.64 1.48 2.81
test the hypothesis that the population of reaction times are identically
distributed for all three drugs at alph=0.05
这是研所的考题，有点不懂题意，试题上只有列卡方跟T的值，所以我在想应该不是在考
ANOVA，可以告诉我怎麽解就可以了，THX

1F：推 chkai:由於不知母体分配 样本数也不够大 所以只能用无母数统计了 02/10 19:05
2F：→ chkai:本题为三相关母体 就用friedman test来检定其中位数是否相等 02/10 19:06
3F：→ chkai:剩下的就自己找书吧 公式在这又点难打 02/10 19:07
4F：→ o5515334:谢谢您罗~!! 02/10 20:21
5F：推 miosis:Friedman无误~k个相关母体检定 02/13 23:30
