Analysis of variance/General steps

==General steps for ANOVAs==


 * 1) Establish the design and type of ANOVA. Clearly identify:
 * 2) IV(s) (categorical)
 * 3) DV(s) (at least interval), and
 * 4) CV(s) (dichotomous or at least interval) - for ANCOVA
 * 5) Develop a hypothesis and/or research question for each main and interaction effect
 * 6) Examine assumptions
 * 7) Examine descriptive statistics and histograms for each cell and marginal totals for the descriptive statistics
 * 8) Create bar, error-bar, or line graph
 * 9) Interpret significance test (F) results and direction of main and interaction effects
 * 10) Conduct follow-up tests if warranted
 * 11) Report and interpret effect sizes
 * 12) * eta-square (omnibus) and partial eta-square
 * 13) * standardised mean effect size (difference b/w two means, e.g., Cohen's d)
