The F distribution is symmetric.

Question

Quizplus · Accepted Answer

The F distribution is not symmetric. It is a right-skewed distribution, meaning that the tail of the distribution is longer on the right side. The F distribution is not always symmetric, as it is influenced by the degrees of freedom of the numerator and denominator. When these degrees of freedom are equal (i.e. F distribution is based on the ratio of two independent chi-square distributions), then the F distribution is symmetric. However, when the degrees of freedom are unequal, the distribution becomes skewed.
