標題[問題] 統計 無母數 還是 ANOVA變異數分析??
時間Fri Feb 10 16:51:30 2012
題目如下
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
這是研所的考題,有點不懂題意,試題上只有列卡方跟T的值,所以我在想應該不是在考
ANOVA,可以告訴我怎麼解就可以了,THX

1F:推 chkai:由於不知母體分配 樣本數也不夠大 所以只能用無母數統計了 02/10 19:05
2F:→ chkai:本題為三相關母體 就用friedman test來檢定其中位數是否相等 02/10 19:06
3F:→ chkai:剩下的就自己找書吧 公式在這又點難打 02/10 19:07
4F:→ o5515334:謝謝您囉~!! 02/10 20:21
5F:推 miosis:Friedman無誤~k個相關母體檢定 02/13 23:30
