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 statistically different when using Tukey’s … WebYour LSD equation looks fine. If you want to get back to variance and you have a summary statistic that says something about variability or significance of an effect then you can almost always get back to variance—-you just need to know the formula. For example, in your equation for LSD you want to solve for MSE, MSE = (LSD/t_)^2 / 2 * b

The Fisher LSD test stands for the Least Significant Difference test (rather than what you might have guessed). The LSD test is simply the rationale that if an omnibus test is conducted and is significant, the null hypothesis is incorrect.
