Key Concepts

Mean

The mean, or expected value, of a random variable is a measure of central tendency that represents the long-run average outcome of a probability distribution. It summarizes where the center of the distribution lies but does not provide information on how much the outcomes spread out around that center.

Variance

Variance is a statistical measure that quantifies the degree of spread or dispersion in the outcomes of a probability distribution. Unlike the mean, which measures central tendency, the variance indicates how much the values deviate from the mean, thereby describing the variability of the distribution.
