Skewness And Kurtosis Difference. Skewness and kurtosis in statistics. The characteristic of a frequency distribution that ascertains its symmetry about the mean is called skewness.
Kurtosis on the other hand measures the bulge peak of a distribution curve. The characteristic of a frequency distribution that ascertains its symmetry about the mean is called skewness. Skewness quantifies a distribution s lack of symmetry with respect to the mean.
Kurtosis is descriptive or summary statistics and describes peakedness and frequency of extreme values in a distribution.
Another less common measures are the skewness third moment and the kurtosis fourth moment. If skewness is between and the distribution is approximately symmetric. The distribution has a lower and wider peak and thinner tails. We use skewness as a measure of symmetry.
