1analysis of variance — n analysis of variation in an experimental outcome and esp. of a statistical variance in order to determine the contributions of given factors or variables to the variance * * * (ANOVA) a statistical method for analyzing the effects of each of… …
2Analysis 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… …
3analysis of variance — ANOVA; variance analysis 1) A commonly used method for examining the statistically significant differences between the means of two or more populations In its simplest form (one way analysis of variance), it involves only one dependent variable… …
4analysis of variance — noun a statistical method for making simultaneous comparisons between two or more means; a statistical method that yields values that can be tested to determine whether a significant relation exists between variables • Syn: ↑ANOVA • Topics:… …
5Multivariate analysis of variance — (MANOVA) is a generalized form of univariate analysis of variance (ANOVA). It is used when there are two or more dependent variables. It helps to answer : 1. do changes in the independent variable(s) have significant effects on the dependent …
6Kruskal-Wallis one-way analysis of variance — In statistics, the Kruskal Wallis one way analysis of variance by ranks (named after William Kruskal and W. Allen Wallis) is a non parametric method for testing equality of population medians among groups. Intuitively, it is identical to a one… …
7Analysis — (from Greek ἀνάλυσις , a breaking up ) is the process of breaking a complex topic or substance into smaller parts to gain a better understanding of it. The technique has been applied in the study of mathematics and logic since before Aristotle,… …
8Method of moments (statistics) — See method of moments (probability theory) for an account of a technique for proving convergence in distribution. In statistics, the method of moments is a method of estimation of population parameters such as mean, variance, median, etc. (which… …
9analysis — /euh nal euh sis/, n., pl. analyses / seez /. 1. the separating of any material or abstract entity into its constituent elements (opposed to synthesis). 2. this process as a method of studying the nature of something or of determining its… …
10Variance — 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… …
