Why do we use a one-tailed test F-test in analysis of variance (ANOVA)? Can you give the reason for using a one tailed test in the analysis of variance test? Why do we use a one-tail test - the F-test - in ANOVA?

#statstab #447 Why do we use a one-tailed test F-test in analysis of variance (ANOVA)?
