Understand randomized posttest only control group, randomized pretest-posttest control group, and Solomon’s four group designs.
Understand randomized posttest only control group, randomized pretest-posttest control group, and Solomon’s four group designs. When can use of a pretest be problematic? How does the Solomon’s four group design address this problem?
What is a pretest-posttest natural control group design? How is it an improvement over the prior three nonexperimental designs?

Understand ex post facto, single group posttest only and single group pretest-posttest designs. What are their weaknesses (i.e., what potential confounds are not controlled)?
