Which of the following is true?
A) We can rule out the possible effects of mediating variables in correlational research.

D) Correlational research cannot demonstrate a causal relationship between two variables.

Question

Quizplus · Accepted Answer

Correlational research is designed to identify whether there is a relationship between two variables, but it does not establish causation. This is because it cannot account for all possible confounding variables that might influence the relationship. Options A, B, and C are incorrect because correlational research cannot rule out mediating variables, a higher correlation coefficient does not confirm causation, and variables with different scales can indeed be correlated using appropriate statistical methods.
