In mathematics, the moments of a function are certain quantitative measures related to the shape of the function's graph. If the function represents mass density, then the zeroth moment is the total mass, the first moment (normalized by total mass) is the center of mass, and the second moment is the moment of inertia. If the function is a probability distribution, then the first moment is the expected value, the second central moment is the variance, the third standardized moment is the s… jr びゅう 日帰りWeb5 jan. 2024 · – The four commonly used moments in statistics are- the mean, variance, skewness, and kurtosis.
