Question

Quizplus · Accepted Answer

It is not practical or ethical to manipulate people's smoking behavior, making it necessary for Dr. Rosenfeld to use correlational research to observe the relationship between smoking and minor physical illnesses. Correlational research can help identify patterns and relationships between variables without intervening or manipulating the variables themselves. Additionally, option A is incorrect, as correlational research does not allow for strong cause-and-effect conclusions. Option B and D are incorrect as they are not relevant to the reason why Dr. Rosenfeld may choose correlational research.
