Question

Quizplus · Accepted Answer

Matched sampling is a technique used in group-design experiments to reduce differences among participants. Researchers match participants based on certain characteristics such as age, gender, or IQ, and assign them to different groups to reduce variability and increase the internal validity of the study. Clones and DNA matching are not used in psychological research, and while statistics are important for analyzing data, they do not directly reduce differences among participants.
