You have been asked to develop a study of the effects of watching Sesame Street on children's gender-role orientations, intelligence, or sociability (select one). Describe how you would design the study using a preexperimental design (one-shot case study, one-group pretest-posttest design, or static-group comparison—select one). Describe how you would design the study using a true experimental design (pretest-posttest control group design, Solomon four-group design, or posttest-only control group design—select one). For both designs, explain why you selected that design and note how you would measure the dependent variable. Note the major advantage and weakness of each design in this particular study. Include one source of internal invalidity for each design and explain why you selected that one.
