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.
