This means we have sufficient evidence to say that the two population variances are not equal. The degrees of freedom basically counts how many free components you have in. Once again the F test statistic is 4.3871 and the corresponding p-value is 0.03825. This means we have sufficient evidence to say that the two population variances are not equal. The F test statistic is 4.3871 and the corresponding p-value is 0.03825. #perform an F-test to determine in the variances are equalį = 4.3871, num df = 9, denom df = 9, p-value = 0.03825Īlternative hypothesis: true ratio of variances is not equal to 1

The following code shows how to perform an F-test using the first method: #define the two groups This tutorial explains how to perform an F-test in R using both methods. The default is “two.sided” but you can specify it to be “left” or “right” instead. Note that alternative indicates the alternative hypothesis to use.
