Counterbalancing Exercise: You want to test the effect of a new drug for treating children with attention deficit disorder and you want every group to take a placebo and also 5 mg, 10 mg, 15 mg and 20 mg of the drug on different days. You know that using the procedure may result in carry over or order effects, so you want to counterbalance the order of presentation of the five dosages.
