If scores on an examination are negatively skewed, it means that there are a few extremely low scores that are pulling the mean score down, resulting in a long left tail. As a result, the median score will be greater than the mean score since the median splits the distribution in half, and the left side (which is skewed) has lower scores. The modal score may or may not be the same as the median, and the peak of the frequency distribution may or may not correspond to the mean score.
