Conduct an analysis of variance (ANOVA) to check for mean differences between three independent groups on any variable of your choice (i.e., Is there a difference in coffee consumption per week between those under age 18, those between 18-25, and those above age 25?). Each sample should have a minimum of n = 6 participants.

What to turn in:

1. State your research question (use the example from above as a model).
2. State the null and alternative hypotheses for your ANOVA.
3. Using = .05 for your test, indicate the critical F-value, conduct the necessary calculations (show your work whenever possible) and state your conclusions regarding the original hypotheses (Reject H₀ or Fail to Reject H₀).
4. Calculate and interpret ² as a measure of effect size.
5. Using Tukey's post-hoc test, check for specific significant differences between groups Note: Please do this even if your conclusion above is "Fail to Reject H₀"
6. Write a conclusion statement, as would appear in a published report.

1. Present your findings using an "ANOVA summary table" as discussed on p. 361 of the textbook. This page here also describes this table.
