Quizplus · Accepted Answer

The size of a correlation coefficient and its interpretation (small, medium, or large) can depend on the context or the reason for calculating the coefficient. Different fields or types of research might have different conventions or expectations for what constitutes a strong or weak correlation. Cohen's and Hemphill's guidelines provide general benchmarks, but the specific reason for calculating the correlation coefficient (e.g., exploring relationships in data, testing a hypothesis) can influence how it should be interpreted.
