F
Distribution
Tables
The F distribution is a right-skewed distribution used most
commonly in
Analysis of Variance. 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. You can use the interactive
F-Distribution Applet to obtain more accurate measures.
