    Question

    What is the empirical relation between mean median and

    mode in positively skewed frequency distribution?
    A Mean < Median < Mode Correct Answer Incorrect Answer
    B Mean > Median > Mode Correct Answer Incorrect Answer
    C Mean = Median = Mode Correct Answer Incorrect Answer
    D Mean – Mode = 3 (Mean – Median) Correct Answer Incorrect Answer

    Solution

    In a moderately skewed distribution, the difference between mean and mode is equal to three times the difference between the mean and median-Mean – Mode = 3 (Mean – Median). In a symmetrical frequency curve, the empirical relation states that mean = median = mode.  In a positively skewed frequency distribution curve, the relation is mean > median > mode. Negatively skewed frequency distribution shows mean < median < mode.
