A data set has a MEDIAN of 64 and a MEAN of 60. Because the mean is pulled below the median, the distribution is:
Show answer and explanation
Correct answer: B. Negatively (left) skewed
- A. In a symmetric distribution the mean ≈ median.
- B. Correct. Mean < median indicates a left (negative) skew (a tail of low values pulls the mean down).

- D. Skew direction, not modality, is indicated by the mean–median relationship.
Note: The recall simply gave the values; this item tests interpreting the mean–median relationship.
