Conduct an analysis of variance (ANOVA) to check for mean differences between three independent groups on any variable of your choice
Question Description
Each sample should have a minimum of n = 6 participants, thus you need a minimum of N=18 participants, total, in the entire study.
What to turn in:
- State your research question (use the example above as a model).
- State the null and alternative hypotheses for your ANOVA.
- Using α = .05 for your test, indicate the critical F-value, conduct the necessary calculations (show your work, as much as possible) and state your conclusions regarding the original hypotheses (Reject H0 or Fail to Reject H0).
- Calculate and interpret η2 as a measure of effect size.
- 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”
