Question

Quizplus · Accepted Answer

A correlational study would be the most effective type of research in this case because it can measure the strength and direction of a relationship between two variables (in this case, cigarette smoking and lung cancer) without manipulating any variables or interfering with natural behavior. This would allow the scientist to determine if there is a statistical relationship between the two variables. A survey would be limited by relying on self-reported data, while laboratory observation and naturalistic observation would not be appropriate as they do not allow for statistical analysis of the relationship between smoking and lung cancer.
