= Super-Poissonian distribution
{wiki=Super-Poissonian_distribution}
The term "super-Poissonian" refers to a statistical distribution that exhibits greater variability or fluctuations than what is observed in a standard Poisson distribution. In a Poisson distribution, which models the number of events occurring in a fixed interval of time or space with a constant mean rate, the variance is equal to the mean. This means that the relative variability of the distribution (usually measured as the coefficient of variation) is constant.
