WebUsing Fisher's LSD method, you specify that each comparison should have an individual error rate of 0.05 (equivalent to a 95% confidence level). Minitab creates these ten 95% confidence intervals and calculates that this set yields a 71.79% simultaneous … WebThe Fisher's LSD test works just like a t testwith one exception. A t test computes a pooled standard deviation from the two groups being compared. 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.
