F-Distribution Variance Calculator

F‑Distribution Variance Calculator

Calculate the variance of an F‑distribution with numerator degrees of freedom $d_1$ and denominator degrees of freedom $d_2$:
$$ \text{Var}(F)=\frac{2\,d_2^2\,(d_1+d_2-2)}{d_1\,(d_2-2)^2\,(d_2-4)}. $$

* Note: $d_2$ must be greater than 4.

Step 1: Enter Parameters

Numerator Degrees of Freedom, $ d_1 $:

e.g., 5

Denominator Degrees of Freedom, $ d_2 $:

e.g., 10 (must be > 4)
