Easy -2.5 This is a trivial recall question worth 1 mark requiring only knowledge that correlation coefficients must lie in [-1, 1]. Since -6/5 = -1.2 is outside this range, no calculation or problem-solving is needed—just basic definitional knowledge.
Which of the following is not a possible value for a product moment correlation coefficient?
Circle your answer.
