DA0-001 · Question #129

Joseph is interpreting a left skewed distribution of test scores. Joe scored at the mean, Alfonso scored at the median, and gaby scored and the end of the tail. Who had the highest score?

The correct answer is C. Alfonso. In a left-skewed (negatively skewed) distribution, the tail extends to the left toward lower values.

Explanation

In a left-skewed (negatively skewed) distribution, the tail extends to the left toward lower values. This pulls the mean below the median, so the typical relationship is: Mean < Median < Mode. Joe scored at the mean (lowest of the three), Alfonso scored at the median (higher than the mean), and Gaby scored at the end of the left tail - the lowest scores in the distribution. Therefore, Alfonso (median) has the highest score among the three.
