WebApr 4, 2024 · One method to do multiple comparisons is Fisher's Least Significant Difference (LSD). Fisher's LSD computes the "least" or minimum value of difference required between two group means. If the difference between two group means is larger than this computed value, then the two groups are declared "significantly different". WebFisher’s Least Significant Difference (LSD) A tool to identify which pairs of means are statistically different. Essentially the same as Duncan’s MRT, but with t-values instead of Q values.
