Barbara,

Good job with your discussion response. Pretest posttest designs may be quasi-experimental, which means that participants are not assigned randomly. A pretest posttest design is an experiment where measurements are taken both before and after a treatment. The design means that you are able to see the effects of some type of treatment on a group. What are the three of the most common types of quasi-experimental designs?
