When performing a two-tailed test,the lower-tailed critical value of the F distribution with n₁ - 1 degrees of freedom in the numerator and n₂ - 1 degrees of freedom in the denominator is exactly equivalent to the reciprocal of the upper-tailed critical value of the F distribution with n₂ - 1 degrees of freedom in the numerator and n₁ - 1 degrees of freedom in the denominator.

Question

Quizplus · Accepted Answer

This statement is true due to the fact that the F distribution is symmetric and the critical values for the upper and lower tails are reciprocal to each other.
