Detailed explanation-1: -Which of the following distributions is used to compare two variances? Explanation: F – Distribution is used when we require for comparing two variances. It uses a f-Test to compare two values of variances.
Detailed explanation-2: -The F-distribution is a particular parametrization of the beta prime distribution, which is also called the beta distribution of the second kind. where U(a, b, z) is the confluent hypergeometric function of the second kind.
Detailed explanation-3: -Uses. The main use of F-distribution is to test whether two independent samples have been drawn for the normal populations with the same variance, or if two independent estimates of the population variance are homogeneous or not, since it is often desirable to compare two variances rather than two averages.
