Negatively skewed distributions are characterized by a majority of the data clustering towards the higher end of the scale, with a long tail stretching towards the lower end. Scores on a very easy test are likely to be negatively skewed because most participants would score high, with fewer participants scoring lower, creating a distribution that skews to the left.
