Answer: One-group pretest-posttest design.

Explanation: A one group pretest-posttest design, is used by researchers to determine the effect of treatment on a particular group. This is done by pretesting a group, modifying or treating the same group and posttesting the group again.

If the results of the pretest and the posttest is significantly different then the difference can be attributed to the modification after the pretest.
