As a secondary mathematics teacher, Hernandez conducted a study that explored whether giving children recess prior to testing helped their test performance. For one of the semesters, he sends half of his classes out for 10 minutes of recess prior to testing for the other half, he provides 10 minutes of free time after the test. Which of the following best represents the design of Hernandez's study?
A) Posttest-only design with nonequivalent groups

D) One-group pretest-posttest design

Hernandez's study involves comparing the test performance of two different groups (those who had recess before the test and those who had free time after the test) without a pretest or multiple testing phases for the same group. This setup does not control for initial group differences, making it a posttest-only design with nonequivalent groups.
