This table shows the F critical value based on the degrees of freedom in the numerator and denominator in the F ratio and the level of alpha you choose.
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.
How to use this table: There are two tables here. The first one gives critical values of F at the p = 0.05 level of significance. The second table gives critical values of F at the p = 0.01 level of significance. Obtain your F-ratio. This has (x,y) degrees of freedom associated with it.
What is the F-Distribution Table? The F-distribution table is a table that shows the critical values of the F distribution. To use the F distribution table, you only need three values: The numerator degrees of freedom; The denominator degrees of freedom
Use the F-table to find the critical value for your F-test. You’ll need to know the significance level, the numerator degrees of freedom, and the denominator DF. In the F-table, its components represent the following:
Tables for the F-distribution are organized somewhat differently from the tables for other distributions. To use these tables you will need to select the level of the test (α) and compute df1 and df2. This document contains tables in two different formats.
qf(c(alpha), df1=dfn, df2=dfd, lower.tail=FALSE) Where dfn refers to numerator degrees of freedom and dfd refers to denominator degrees of freedom.

The F-distribution table provides critical values for different levels of significance (alpha) and degrees of freedom. Find the value you need here.
Table entries are critical values for F* with probably p in right tail of the distribution. Figure of F distribution (like in Moore, 2004, p. 656) here. Critical values computed with Excel 9.0.

CRITICAL VALUES OF THE F DISTRIBUTION (1/6) The obtained F is significant at a given level if it is equal to or greater than the value shown in the table. The α=0.05 points on the F distribution are shown in the top row, and the α=0.01 points are shown in the bottom row.
