Fisher F Test with signifi cantly low values in small samples
Testing for differences between groups is usually done with the Fisher-F test. In practice, it has been known to return unusually small, but significant values. This situation is seldom covered by theory, usually being considered a fault of the model or of the analysis. This paper looks at a real li...

Summary: | Testing for differences between groups is usually done with the Fisher-F test. In practice, it has been known to return unusually small, but significant values.
