WebThe Fisher's LSD test begins like the Bonferroni multiple comparison test. It takes the square root of the Residual Mean Square from the ANOVA and considers that to be the pooled SD. Taking into account the sample sizes of the two groups being compared, it computes a standard error of the difference between those two means. WebMEANS TRT / LSD; (can use T instead of LSD for same results) ﬁStoryﬂ is: the overall AOV test protects the EER for the mean comparisons. Ł story based on simulations from early ’70s Ł it is not really true for many means Ł still recommended statistical practice, when EER is not taken too seriously
