PSYCH 100A Lecture Notes - Lecture 13: Repeated Measures Design, Type I And Type Ii Errors, John Tukey
Document Summary
Anova used to evaluate hypotheses about means of more than two samples test any number of pairwise ( 1= 2) and complex hypotheses. Post-hoc test: post-hoc means after the fact after the anova only completed after anova resulted in the rejection of the null hypothesis it is run after we have already gured out that things are different. Tukey honestly signi cant different (hsd) test takes into account type i error rate looks at all potential pairwise pairs uses q distribution q distribution and the q statistic. We are looking at data from 4 different societies (foraging, farming, natural resources, industrial ) and if there is any signi cant difference between how fair ( eg bigger percentage of money given to other people) the different groups behave. Gm = 39. 385: ms within, ms within = ss within / df within degrees of freedom. 9 is the within groups degrees of freedom df within = 9: ss within variance within.
