Question: Bring to mind a real-world situation or problem that could be addressed using a one-way analysis of variance (ANOVA).

Post the real-world situation or problem you selected to address, the independent and dependent variables you would study and the number of levels of the independent variable, the statistical null and alternative hypotheses, a description of what information the effect size would tell you that the probability value would not tell you, explain what additional information confidence intervals around means (or around mean differences) would give your reader; explain when would you need to report a post hoc test and why; and using realistic numbers for values of degrees of freedom, sample size, F-ratio, confidence interval (s) (if appropriate), and post hoc results (if appropriate), report hypothetical results in a few sentences using correct APA format.
