This video introduces the variance
This video introduces the variance ratio F test and describes how it works. A step-by-step description of how to perform the F-test is described.
This is the test that is commonly used to determine if two population variances are equal or not.
The way in which this two-tailed test can be mistaken for a one-tailed test is discussed.
The video also discusses the weakness of the F-test in terms of its assumption of normality of data distributions.
This is the video that answers the questions: how do I do an F-test?
