(2) Describe how you would design the study using a true experimental design (pretest-post test control group design, Solomon four-group design, or post test-only control group design -- select one).

For both of the designs you have to explain why you would select that design AND note how you would measure the dependent variable. Note the major advantage & weakness of each design in this particular study. Include 1 source of internal invalidity for each design & explain why you selected that one.
