Question

Quizplus · Accepted Answer

The rejection region for Fobs (observed F-value in an F-test) is always in the right tail of the sampling distribution of F. This is because F-tests are used to compare variances and the F-distribution is always positively skewed, meaning larger F-values (which fall in the right tail) indicate a more significant difference between the variances being compared.
