The Fisher LSD test uses the pooled standard deviation. This pooled SD comes from all the groups, which gives it more degrees of freedom and more power.

WebOne way to do this is by using Fisher's Least Significant Difference (LSD) test. How the Fisher's LSD test works The 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. WebIn statistics, Fisher's method, [1] [2] also known as Fisher's combined probability test, is a technique for data fusion or "meta-analysis" (analysis of analyses). It was developed by and named for Ronald Fisher. In its basic form, it is used to combine the results from several independence tests bearing upon the same overall hypothesis ( H0 ).

This is a method to compare all possible means, two at a time, as t -tests. Unlike an ordinary two-sample t -test, however, the method does rely on the experiment-wide error (the MSE). The LSD is calculated as:
