Reliability & Life Testing Handbook, Volume 2

This table gives the values of F such that
for selected values of m, the number of degrees of freedom of the numerator of F, or the first degrees of freedom; and for selected values of n, the number of degrees of freedom of the denominator of F, or the second degrees of freedom. The table also provides values corresponding to F( F) = 0.10, 0.05, 0.25, 0.025, 0.01, 0.005, 0.0025, 0.001 since F 1-? for m and n degrees of freedom is the reciprocal of F ? for n and m of degrees of freedom. Thus,
