A research team has developed a new medication to treat ADHD. They think that their new medicine will be more effective than the current medication. The team asks local doctors to perform study in which newly diagnosed children with ADHD (n = 20) are matched with other children taking the current medication (n= 20) based on symptoms and physical attributes of the children. The research team will then test all the children after one year to determine the effectiveness of the treatments with a standardized symptom score-sheet (scores can range from 1-50).
