a quantity that expresses the average or expected value of the first, second, third, or fourth power of the deviation of each component of a frequency distribution from some given value, typically mean or zero. The first moment is the mean, the second moment the variance, the third moment the skew, and the fourth moment the kurtosis.
The first, second, third, and fourth moments of a data set respectively provide information about the mean, variance, skewness, and kurtosis of the distribution.
