Quizplus · Accepted Answer

Fatima is using matched samples by selecting only children who have received identical amounts of supervision during the day to control for the third variable of lack of teacher supervision. Matched pairs would involve pairing individual children based on similar characteristics, but this is not necessary in this case since Fatima is only interested in controlling for a single variable. Matched supervisors and double-blind observation are not relevant to this scenario.
