A distribution that is asymmetrical.
n. the dispersion of a set of observations (e.g. of heights, weights, or blood pressures) about their arithmetic *mean. A normal or Gaussian distribution is a continuous distribution that is symmetrical around the mean value and in which a large majority of the observations fall within one *standard deviation of the mean in either direction: such a distribution forms the familiar symmetrical bell curve when plotted on a graph. In a skewed or asymmetrical distribution, the measurements are clustered on one side of the mean and spread out over a wider range on the other.
