Document Summary
Can we conclude that the intervenion program caused the diference in outcomes: yes, criicism of rauh et al. This is experimental research and we know that this experiment works but we aren"t sure how it works. In class exercise: which of these diferences could be tested experimentally: diference in reported weekly alcohol intake among college students vs. non-college atending adults. Alcohol is the dependent variable, and the iv could be the college adults (but can"t manipulate college students). So no: diferences in men"s and women"s creaive ability. Dependent variable is creaive ability, and iv is gender. So no: diferences in cogniive ability among african american men who perform 1 hour vs. 4 hours of aerobic exercise. Dv is cogniive ability, and the iv would be 1 hour vs. 4 hour of exercise. This can be tested: diferences in nonverbal behavior among people on 15mg vs. 80 mg. of cafeine.
