F Distribution Tables. The shaded area in the diagram represents the level of signiﬂcance ﬁ shown in the table. Lower one-sided critical values may be found from these tables by reversing the degrees of freedom and using the reciprocal of the tabled value at the same significance level (100 minus the percent for the percentile). 0000004456 00000 n 0000013087 00000 n F Distribution Table C-5 Percentiles of the F Distribution .
