Document Summary

Caffeine and aging a very unethical study. To assess the effects of caffeine on memory in people of difference age groups, a very unethical researcher gave caffeinated and de-caffeinated coffee to adults and babies. If there is a significant interaction, further explore the effect with simple effects analysis. How does the present pattern of results highlight the advantage of factorial anova. (hint: how would you results look if it were to conduct two separate one-way anovas). Here are the resulting memory scores, a higher score is better: Null hypotheses: (adults) = (babies, (caffeinated) = (de-caf , no significant interaction between age and caffeine. There is no significant main effect of age. There is no significant main effect of caffeine. There is a significant interaction between age and caffeine. Simple effects approach 1 testing the effect of caffeine @ age. Sscaffeine @ babies = 18; df = 1; mscaffeine @ babies = 18; f = 18/1 = 18; reject ho.
