Laura · Answer 1

Answer:pretest/posttest

Explanation:

A pretest-posttest refers to a experiment in which individuals in a study participate before and after the experiment. This is done so that a researcher may examine if manipulation of the experiment changes the result obtained from the participants. In this design there is only one large group used for the experiment.

This is done to examine and establish if changing something can influence the participants. The manipulation is constant throughout all the participants since the participants are studied before and then after the manipulation of the experiment.
