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. WebAn older approach, no longer offered in many statistical computing packages, is Fisher’s Protected Least Significant Difference (LSD). 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:
