The difference between a two-way and a three-way ANOVA is the amount of independent variables that are in the tests. A two-way ANOVA has two independent variables while a three-way ANOVA has three independent variables (Jackson, 2012).
The main effect is the amount of practice a participant gets over a certain amount of time. All other variables were insignificant.
The effect size is about 83.3% which is the same as the variance. This variance is attributable to how much practice participants had.
When determining which one is better it would depend on the kind of experiment that a researcher is trying to conduct. Multiple independent variables allows a researcher to control multiple variables and deciding which one has the effect that the
