F Test Statistic Table. The variance ratio f is computed as. 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.
Examples of how to use the f distribution table. This f table to find the critical value of f is also available in pdf format too users may download this table in pdf format to refer it later offline. 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.
The degrees of freedom are computed.
If the f statistic is greater than the critical value found in the table then you can reject the null hypothesis of the f test and conclude that the results of the test are statistically significant. F s 1 2 s 2 2 w h e r e s 1 2 s 2 2. 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 are computed.
