Standard deviation
Standard deviation: The square root of variance, expressing dispersion in the same unit as the observed variable. It is outlier-sensitive because it derives from squared deviations. In a Gaussian it describes scale, but not every distribution follows Gaussian rules. This perspective connects the definition with practical behaviour in artificial intelligence systems.
