F Distribution Tables
The F distribution is a right-skewed distribution used most commonly
in Analysis of Variance The F distribution is a ratio of two Chi-square
distributions, and a specific F distribution is denoted by the degrees
of freedom for the numerator Chi-square and the degrees of freedom for
the denominator Chi-square. When referencing the F distribution, the numerator
degrees of freedom are always given first, as switching the order of degrees
of freedom changes the distribution (e.g., F(10,12) does not
equal F(12,10)). For the four F tables below, the rows represent
denominator degrees of freedom and the columns represent numerator degrees
of freedom. The right tail area is given in the name of the table. For
example, to determine the .05 critical value for an F distribution with
10 and 12 degrees of freedom, look in the 10 column (numerator) and 12
row (denominator) of the F Table for alpha=.05. F(.05, 10, 12)
= 2.7534.
