Quizplus · Accepted Answer

An experimental design would be the best choice because it allows for manipulation of the independent variable (caffeine) and measurement of its effects on task performance in both introverts and extraverts. This would provide more control over potential confounding variables and allow Jacques to make causal inferences about the relationship between caffeine consumption and task performance.
