It is a measure of symmetry, or more accurately, the lack of symmetry. A distribution, or data set, is symmetric if it looks the same on the left and right of the center point. skewness of a normal distribution is zero, and symmetric data should have a skewness
near zero. Negative values of skewness indicate data that are skewed left and positive values for the skewness indicate data that are skewed right
