WebJan 16, 2011 · Fisher's LSD (Least Significant Difference) The LSD test is a procedure for testing the difference between the simplest and most used treatment means. This method was introduced by Fisher (1935), so it is also known as the Fisher's LSD [Least Significant Difference] Method. WebThe Fishers LSD test is basically a set of individual t tests. The only difference is that rather than compute the pooled SD from only the two groups being compared, it computes the pooled SD from all the groups. If all groups are sampled from populations with the same SD, using all the data to compute the pooled SD gives a more accurate value ...
