Question

Quizplus · Accepted Answer

The absolute value of the correlation coefficient (|r|) is always between 0 and 1, so option B is true. Option A and C have incorrect inequality signs. Option D has the correct inequality, but it also includes absolute value signs, which is incorrect. Option E is false since the correlation coefficient can be equal to itself.
