“The participants certainly differ⟳ in how their practice is distributed (1, 2, or 3 days), but they also differ⟳ in how much total practice they get⟳ (3, 6, or 9 hours). This is a perfect example of a confound—it is impossible to tell⟳ if the results are due to one factor (distribution of practice) or the other (total practice hours); the two factors covary perfectly.”
