Question

Quizplus · Accepted Answer

The test for equality of two population variances is based on the ratio of the two sample variances, which is known as the F-test. This test compares the variance of two samples to determine if they are from populations with the same variance. The F-test is used to test hypotheses concerning the equality of two variances and is based on the F-statistic, which is the ratio of the variances of the two samples.
