    Question

    If the correlation coefficient (r) between two variables

    is -0.85, it indicates:
    A A weak negative relationship. Correct Answer Incorrect Answer
    B No relationship. Correct Answer Incorrect Answer
    C A perfect negative relationship. Correct Answer Incorrect Answer
    D A strong negative linear relationship. Correct Answer Incorrect Answer
    E A strong positive linear relationship. Correct Answer Incorrect Answer

    Solution

    The correlation coefficient (r) ranges from -1 to +1. Its absolute value indicates the strength: 0 = no linear relationship, ┬▒1 = perfect linear relationship. Values closer to ┬▒1 indicate strong relationships. Here, |-0.85| = 0.85 suggests a strong negative linear relationship.
