Skewness, in statistics, is the degree of distortion from the symmetrical bell curve, or normal distribution, in a set of data. Skewness can be negative, positive, zero or undefined.

Skewness: Skewness is defined as the degree of asymmetry about the central value of distribution. Skewness can be positive as well as negative. If the mean is greater than mode or the median, the skewness will be positive. If it is less Skewness will be negative.
