WebFisher’s Least Signiflcant Difierence (LSD) Test Lynne J. Williams ¢ Herv¶e Abdi 1 Overview When an analysis of variance (anova) gives a signiflcant result, this indicates that at least one group difiers from the other groups. Yet, the omnibus test does not indicate which group difiers. In order to analyze the pattern of difierence ...
