Finding F critical for Variances

Use the F-distribution to find the degrees of freedon for the numerator (d.f.N.), the degrees of freedom for the Denominator (d.f.D.) and the critical F-value

Use the closest value when looking up the d.f.N. and d.f.D. in the tables.

Test	alpha α	Sample 1	Sample 2	d.f.N.	d.f.D.	F critical
Right	0.01	s₁²₌₃₇ n1=14	s₂²₌₈₉ n2=25
Two-tailed	0.10	s₁²₌₁₆₄ n1=21	s₂²₌₅₃ n2=17
Right	0.05	s₁²_=92.8 n1=11	s₂²_=43.6 n2=11
