F Test Statistic Table. That is v 1 degrees of freedom for sample having larger variance n 1 1. For locating the f e critical value of f in the table quickly users can supply the values of degrees of freedom df and significance level α directly in the above interface.

The degrees of freedom of the larger estimate of the population variance are denoted by v1 and the smaller estimate by v2. F s 1 2 s 2 2 w h e r e s 1 2 s 2 2. 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.
The variance ratio f is computed as.
The variance ratio f is computed as. The estimated value of f or f statistic f 0 is compared with the critical value of f from f distribution table to check the significance of results. P 0 01 p 0 001 chi square statistics. Examples of how to use the f distribution table.
