Normal distributions are important in statistics and are often used in the natural and social sciences to represent real-valued random variables whose distributions are not known.[1][2] The normal distribution is useful because of the central limit theorem. In its most general form, under some conditions (which include finite variance), it states that averages of random variables independently drawn from independent distributions converge in distribution to the normal, that is, become normally distributed when the number of random variables is sufficiently large. Physical quantities that are expected to be the sum of many independent processes (such as measurement errors) often have distributions that are nearly normal.[3] Moreover, many results and methods (such as propagation of unce

The Gaussian (normal) distribution was historically called the law http://introcs.cs.princeton.edu/java/11gaussian/ of errors. It was used by Gauss to model errors in astronomical observations, which is why it is usually referred to as the Gaussian distribution. The probability density function for the standard Gaussian distribution (mean 0 and standard deviation 1) and the Gaussian distribution with mean μ and standard deviation σ is given by the following formulas. The cumulative distribution function for the standard Gaussian distribution and the Gaussian distribution with mean μ and standard deviation σ is given by the following formulas. As the figure above illustrates, 68% of the values lie within 1 standard deviation of the mean; 95% lie within 2 standard deviations; and 99.7% lie within 3 standard deviations. Central limit theorem. Under generous technical conditions, the distribution of the sum of a large number of independent random variables (approximately) has a normal distribution. In science and engineering, it is often reasonable to treat the error of an observation as the result of many small, independent, errors. This enables us to apply the central l
