The F distribution is a right-skewed distribution used mostcommonly inAnalysis of Variance. When referencing the F distribution, the numerator degrees of freedom are always givenfirst,as switching the order of degrees of freedom changes the distribution(e.g.,F(10,12) does not equal F(12,10) ). For the fourFtables below, the rows represent denominator degrees of freedom and thecolumnsrepresent numerator degrees of freedom. The right tail area is given inthe name of the table. For example, to determine the .05 critical valuefor an F distribution with 10 and 12 degrees of freedom, look in the 10column(numerator) and 12 row (denominator) of the F Table for alpha=.05. F(.05,10, 12) = 2.7534. You can use the interactiveF-Distribution Applet to obtain more accurate measures.
