Fisher's lsd method
WebThe least significant difference (LSD) test is used in the context of the analysis of variance, when the F -ratio suggests rejection of the null hypothesis H 0, that is, when the difference between the population means is significant. This test helps to identify the populations whose means are statistically different.
