Details

Hays (1994; section 13.21, table 13.21.2, p. 570) describes a experiment wherein 12 participants complete four puzzles each. Puzzles could be either square or round, and either monochromatic or in color. Each participant completed every combination of the two factors.

Examples

data(puzzles)

## classical ANOVA
## Both color and shape are significant, interaction is not
classical <- aov(RT ~ shape*color + Error(ID/(shape*color)), data=puzzles)
summary(classical)

## Bayes Factor
## Best model is main effects model, no interaction
anovaBF(RT ~ shape*color + ID, data = puzzles, whichRandom = "ID", progress=FALSE)
