ANOVA Analysis

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

For this situation or problem:

1. Clearly identify the independent and dependent variables you would study, including the number of levels of the independent variable.

2. Generate the statistical null and alternative hypotheses.

3. Describe what information the effect size would tell you that the probability value would not tell you.

4. Explain what additional information confidence intervals around means (or around mean differences) would give your reader.

5. Explain when would you need to report a post hoc test and why.

6. Using realistic numbers for values of degrees of freedom, sample size, F-ratio, and confidence interval(s) (if appropriate), and post hoc results (if appropriate), report hypothetical results in a few sentences using correct APA format.

## One Way ANOVA: Real world situation

Think about a real-world situation that can be addressed using a one-way ANOVA. For this situation, clearly state the independent and dependent variables you would study; generate the null and alternative hypothesis; explain why you would need a post hoc analysis; and using realistic numbers for values of df, n, f-ratio, confidence intervals and post hoc results, report hypothetical results in a few sentences.

This "real world" can be just about anything..can be simple.
