Fisher's least significant difference method (LSD)substitutes the pooled variance estimator from the equal variances t-test with the MSE from ANOVA.
Fisher's LSD
A statistical method used to compare means while controlling for familywise error rate in the context of an ANOVA.
Pooled Variance Estimator
An estimate of variance that combines the variances from two or more samples, assuming that they come from populations with the same variance.
MSE from ANOVA
Mean Square Error derived from Analysis of Variance, indicating the average of the squares of the deviations of observations from their group means.
