In a frequency distribution that is positively skewed, the correct relationship among measures of central tendency is:
- A Mean = Median = Mode
- B Mode > Median > Mean
- C Mean > Median > Mode ✓
- D Median > Mean > Mode
Correct answer: C. Mean > Median > Mode
Explanation
In a positively (right) skewed distribution, the long tail pulls the mean toward higher values, so Mean > Median > Mode. The mode is the lowest (peak of the left-shifted distribution), the median lies between, and the mean is highest due to influence of extreme values. In negatively skewed distributions, the order is reversed: Mean < Median < Mode.
