Document Summary

One way anova: k = number of groups i = group number; j = number of samples in ith group (group size) Distribution of yij has common variance and equal variance. 5 steps: ho = all (cid:373)u"s equal; ha = (cid:374)ot all (cid:373)u"s equal, state alpha, f test (f~fi-1,n-i under the null, conclusion (e. g. that is, there is strong evidence to suggest group a > group b) Interpret (e. g. given fobs > f*, we reject the ho) Pairwise test: comparing two groups within an anova. If using ci, reject ho if ci does not cover 0. Calculate variance, standard deviation using all groups (group pooled sd or variance) (continue until all groups are covered, not just the compared groups, and subtract by # of group) H0: gamma = 0 vs ha: gamma =/= 0.
