F Test Table. The degrees of freedom of the larger estimate of the population variance are denoted by v1 and the smaller estimate by v2. The degrees of freedom are computed.
The degrees of freedom of the larger estimate of the population variance are denoted by v1 and the smaller estimate by v2. To perform f test go to the data menu tab and from the data analysis option select f test two sample of variances. Df 1 2 3 4 5 7 10 15 20 30 60 120 500 1000.
F distribution critical values.
The f distribution table is used to find the critical value for an f test. Below are the steps where the f test formula is used to the null hypothesis that the variances of two populations are equal. The variance ratio f is computed as. Firstly frame the null and alternate hypothesis.
