Statistical characteristics of frequency distributions:

• Moments are mathematical constants that define and characterize the shape, center, dispersion, skewness, and kurtosis of a probability distribution.
• The first raw moment about the origin represents the Mean; the second central moment represents the Variance; the third and fourth central moments measure Skewness and Kurtosis respectively.
• Hence, moments encapsulate all essential characteristics of a distribution.
