The type of Inferential Tests depend on data Repeated measures ? UnMatched groups (groupes “indépendants”: different subsets of the population in each condition Matched groups (groupe “appareillés”): the same individuals in each condition Type of data Metric  mean, SD, …. Ranks: 1,2,3,4,5,6,7,8,9,10 Categories: 49% “yes”, 33 “no”, 18% “no opinion”
