Definitions:

F-test

A statistical test that compares the variances of two populations to ascertain if they come from distributions with equal variances.

Mean Square Error (MSE)

MSE is a measure of the quality of an estimator—it is always non-negative, and values closer to zero are better. It is the average of the squares of the errors or deviations—that is, the difference between the estimator and what is estimated.

Mean Square Treatments (MST)

A measure used in analysis of variance (ANOVA) to evaluate the variance within treatment groups, helping to identify whether differences between groups are statistically significant.

Test Statistic

A statistic calculated from sample data, used to decide whether to reject the null hypothesis in hypothesis testing.
