Fisher's lsd test

WebAccording to the LSD Post-Hoc Test Output, the LSD value of our example is equal to 14.882 and is smaller than abslolute differences between the means of the samples 1 and 3, which is 26.20. Therefore there is a significant difference between these samples. Analogical is the situation between the samples 2 and 3. Test Results WebFisher’s LSD versus Tukey’s LSD. With Tukey’s procedure it is more difficult to find a difference than with Fisher’s protected LSD. For example treatments 2, 5, and 4 are not …
