The given experimental design is a pretest-posttest control group design, as it involves random assignment of subjects to either a control or experimental group, testing both groups before and after the treatment for comparison, and having a control group tested at the same two times without the treatment to establish a baseline for comparison. A posttest-only control group design involves only testing the control and experimental groups after the treatment, while a one-group pretest-posttest design lacks a control group for comparison. Compromise design is not a recognized experimental design term.
