Variance — In probability theory and statistics, the variance of a random variable, probability distribution, or sample is one measure of statistical dispersion, averaging the squared distance of its possible values from the expected value (mean). Whereas… … Wikipedia
Standardized coefficient — In statistics, standardized coefficient or beta coefficient is the estimate of an analysis performed on variables that have been standardized so that they have variances of 1. This is usually done to answer the question which of the independent… … Wikipedia
Standardized moment — In probability theory and statistics, the k thstandardized moment of a probability distribution is frac{mu k}{sigma^k}! where mu k is the k th moment about the mean and sigma; is the standard deviation.It is the normalization of the k th moment… … Wikipedia
Analysis of variance — In statistics, analysis of variance (ANOVA) is a collection of statistical models, and their associated procedures, in which the observed variance in a particular variable is partitioned into components attributable to different sources of… … Wikipedia
