F Distribution Table

The F distribution are commonly used for the analysis of variance. It is a right skewed distribution function. While referring to the F distribution table, the numerator degrees of freedom are always given first, as switching the order of degrees of freedom changes the distribution. The below Degrees of Freedom table lists with values of F distribution for alpha 0.5. For example, to determine the 0.5 critical value for an F distribution with 5 and 10 degrees of freedom, look in the 5 column (numerator) and 10 row (denominator) of the F distribution Table for alpha 0.5. F(0.5, 5, 10) = 3.33.
