  Critical Values of the Fisher F-Distribution at a Probability Level of 0.01

The table below contains critical values of the Fisher F-distribution at a probability level (p-value) of 0.01.

To view a table of critical values for the Fisher F-distribution at a probability level (p-value) of 0.05, click here.
  1. df1 refers to the numerator degrees of freedom.
  2. df2 refers to the denominator degrees of freedom.
  3. When the result of an F-test with df1 and df2 degrees of freedom is larger than the associated value in the table, then the F-test is significant at the 0.01 level or below (i.e., p < 0.01).
