The pretest-posttest control-group design is a strong research design in which a group of research participants is randomly assigned to an experimental and control group. Both groups of participants are pre tried on the dependent variable and t hen post tried after the experimental treat! ment condition has been administered to the experimental group. ? This is an resplendent research design because it includes a control or coincidence group and has random assignment. ? This design controls for all of the standard threats to internal validity.
