statistical distribution
subject			fact

statistical distribution	has definition The range of variation of some quantity in a population, obtained by sampling many members of the population. For example, the statistical distribution of the height of American males could be obtained by sampling 10,000 randomly chosen males and counting the number of them within each range of heights. In cosmology, the distance between pairs of galaxies, averaged over a large number of galaxies, would constitute a statistical distribution.
	is a kind of statistical concept

Kinds of statistical distribution :

• frequency distribution (2 facts) - A statistical arrangement of numerical data according to size or magnitude (see also distribution function).
• Gaussian distribution (3 facts) - A statistical distribution defined by the equation p = c exp(-k²x²), in which x is the statistical variable. It yields the familiar bell-shaped curve. Accidental errors of measurement and similar phenomena follow this law., A random distribution of initial conditions is often referred to as a Gaussian distribution. Also, a certain kind of bell-shaped curve is called a Gaussian.
• Maxwell distribution (3 facts) - An expression for the statistical distribution of velocities among the molecules of a gas at a given temperature., The distribution function that any species of particle will have if it is in thermodynamic equilibrium. This distribution function describes both the equilibrium in velocity space or kinetic energy, and the equilibrium in potential energy.
• Poisson distribution (2 facts) - An approximation to the binomial distribution used when the probability of success in a single trial is very small and the number of trials is very large.
