Correlation concept essentials – UGC NET Question

Statement A is correct because correlation quantifies both direction and strength of linear association. Statement C is true as a value near zero indicates weak or no linear correlation. Statement D is also correct because correlation alone cannot establish cause and effect. Statement E accurately states that in negative correlation, higher values of one variable are associated with lower values of the other. Statement B is false since +1 represents perfect positive, not negative, linear relationship. Therefore, A, C, D and E only are correct.

Option A:
Option A is incomplete since it omits D (correlation is not causation).

Option B:
Option B is incomplete because it omits C and does not include the full correct set.

Option C:
Option C is incorrect because it excludes A (definition) and omits D (causation warning).

Option D:
Option D is correct as it joins all four accurate statements and excludes only B, which misstates the meaning of +1.
