Fisher lsd minitab

WebFisher's least significant difference (LSD) procedure is a two-step testing procedure for pairwise comparisons of several treatment groups. In the first step of the procedure, a global test is performed for the null hypothesis that the expected means of all treatment groups under study are equal. WebThe flrst pairwise comparison technique was developed by Fisher in 1935 and is called the least signiflcant difierence (lsd) test. This technique can be used only if the anova F omnibus is signiflcant. The main idea of the lsd is to compute the smallest signiflcant difierence (i.e., the lsd) between two means as if these
