Correlations close to +1.0 or -1.0 indicate a strong relationship between variables, while correlations close to 0 indicate a weak relationship. A correlation does not necessarily imply causation, and both positive and negative correlations can be meaningful depending on the context. Therefore, options A and B are not accurate statements about correlations, and option D is incorrect because correlation does not imply causation.
