MATHEMATICAL ASPECTS. If in an analysis of variance the F-ratio leads to rejection of the null hypothesis H 0, we can perform the LSD test in order to detect which means have led H 0 to be rejected.

WebExample of Fisher's LSD method. For example, you are measuring the response times for memory chips. You take a sample of 25 chips from five different manufacturers. The ANOVA resulted in a p-value of 0.01, leading you to conclude that at least one of the … Thus, we can proceed to perform Fisher’s least significant difference test to determine which group means are different. Using values from the output of the ANOVA, we can calculate Fisher’s test statistic as: LSD = t.025, DFw * √ MS W (1/n 1 + 1/n 1) LSD = t.025, 27 * √ 36.948*(1/10 + 1/10) LSD = 2.052 * √ 7.3896; LSD = 5.578
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.
