Fisher's least significant difference method
WebNov 12, 2024 · One of such methods is the Fisher’s Least Significance Difference method where we calculate the LSD value. The LSD utilizes a t-statistic to perform pairwise comparisons via a form of confidence interval. It can be applied to groups of same sample size as well as different sample sizes. Once we calculate the LSD value, we then … WebThe Scheffé method covers all possible contrasts, and as a result, is the most conservative of all the methods.
