Quizplus · Accepted Answer

A repeated-measures design is a type of related-samples design in which participants are observed more than once. Matching is not necessarily involved in this type of design, although it is possible to match participants on certain variables if desired. Therefore, option B) matched-pairs design and option C) matched-samples design are not the best choices. Option D) all of these is not a correct answer because not all related-samples designs involve matching.
