In a distribution that is positively skewed, the correct order of measures of central tendency is:
- A Mode > Median > Mean
- B Mean = Median = Mode
- C Mean > Median > Mode ✓
- D Median > Mean > Mode
Correct answer: C. Mean > Median > Mode
Explanation
In a positively skewed distribution (tail on the right), the mean is pulled furthest to the right by the extreme high values, followed by the median, with the mode at the peak of the distribution (lowest). The relationship is: Mean > Median > Mode. In a negatively skewed distribution, the opposite holds: Mode > Median > Mean.
