Rejection Region

Rejection region is the range of values in hypothesis testing that leads to the rejection of the null hypothesis if the test statistic falls within this range.

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.
