F Distribution Mean

F Distribution Mean - Solve mathematical problems with step-by-step solutions.

F-Distribution Mean

The mean of the F distribution with degrees of freedom d₁ and d₂ is d₂/(d₂−2) for d₂ > 2.

Formula

E[F] = d₂/(d₂ − 2), valid for d₂ > 2.

Example

With d₁=5, d₂=10 → mean = 10/(10 − 2) = 1.25.

FAQs

When undefined?
Mean is undefined if d₂ ≤ 2.

Variance?
Exists only for d₂ > 4.
