Michael Mendelson designed an experiment to test the theory that students with higher levels of cultural capital will have more academic success in high school.Worried that he might compromise internal validity by unconsciously signaling his expectations to participants,Michael hires research assistants who are trained to administer the experiment,but who are unfamiliar with Michael's research questions and hypotheses.What kind of experimental research are Michael and his research assistants conducting?

Researcher Zoe Zednick wanted to test the effectiveness of a new anger management treatment session at the Prairie County social work agency.She assembled 24 clients who had been referred for anger management and divided them randomly into two groups of 12.One group was assigned to the new anger management session while the other group went to a traditional anger management session.Each group was given an intake assessment that measured anger management skills.After clients finished the sessions,Zednick measured the level of anger management skills for all subjects in both groups.What experimental design did she use?
