Conduct an a n a l y s I s 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.

1. State y. O u r 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 (RejectH0 or Fail to RejectH0).
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 d o t h i s even if your conclusion above is "Fail to Reject H0"
6. W r I t e a conclusion statement, as would appear in a published report.
