Kurtosis measures how steep or flat the distribution is with respect to a true normal distribution.Kurtosis coefficients above zero indicate a curve that is steep in the center, and the tails are long; values less than zero indicate the curve is flat in the center, and the tails are short.Skewness measures the asymmetry of the data distribution.Values greater than zero indicate the upper tail of the curve is longer than the lower tail, and values less than zero indicate the opposite.Skewness and kurtosis calculations are usually performed with computer software.
