variance Algorithm

variance has a central character in statistics, where some ideas that use it include descriptive statistics, statistical inference, hypothesis testing, goodness of fit, and Monte Carlo sampling. In probability theory and statistics, variance is the expectation of the squared deviation of a random variable from its mean. The great body of available statistics show us that the deviations of a human measurement from its average follow very closely the normal law of mistake, and, therefore, that the variability may be uniformly quantify by the standard deviation corresponding to the square root of the average square mistake. When there are two independent causes of variability capable of produce in an otherwise uniform population distributions with standard deviations. It is therefore desirable in analyze the causes of variability to deal with the square of the standard deviation as the measure of variability.
