• In physics, a fluctuation is a variation in an extensive or intensive quantity, such as energy, density or voltage, from its spatial or temporal average. The mean-square fluctuation ^2 is equivalent to the variance in statistics. If Xi are i data points X,

the mean-square fluctuation is calculated as: mean(square(Xi)) - square(mean(Xi)).

• In thermodynamics, a fluctuation is a perturbation in an equilibrium or far-from-equilibrium thermodynamic system.
• In economics, fluctuation is a critical combination of events.
