Details

Options:

• 'SS type': type of sum of squared, default: type = 2. See Details in Anova

• 'Effect size': compute and prints effect size (partial eta squares)

• 'Summary statistics for groups': prints summary statistics for groups formed by all combinatuions of factors

• 'Pairwise comparisons of means': performs post-hoc Tukey's HSD test on significant (p < .05) or close to significant (p < 0.1) effects.

On OK, the following operations are carried out:

• Computes ANOVA using Anova

• Computes effect sizes (partial eta squared)

• Prints a summary of marginal statistics (count, min, max, mean, ds)

• runs post-hoc analysis on significant or close to significant effects

• Generates an 'extended' dataset (extension .ext) containing additionak columns '<factorA.factorB:...>' that allows differentiate measures from groups or subjects with same factors levels. This 'extended' dataset is useful for ploting means and post-hoc analysis
