ANOVA stands for an alysis va riance, a method by which the source of variability is identified. This method is widely used in industry to help identify the source of potential problems in the production process, and identify whether variation in measured output values is due to variability between various manufacturing processes, or within them. By varying the factors in a predetermined pattern and analyzing the output, one can use statistical techniques to make an accurate assessment as to the cause of variation in a manufacturing process.

Analysis Of Variance is based on comparison of estimates of variances. In general this looks at the ratio of the amount of variation accounted for by the fitted model or specific part of the model (e.g. regression model, treatments) to that accounted for by random error, allowing for the fitted model. The ratio is then compared with an F distribution.

Analysis of Variance. Researchers use this statistical procedure to test differences between means of two or more groups.

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

a guide for determining whether or not an event was most likely due to the random chance of natural variation

A method of statistical analysis broadly applicable to a number of research designs, used to determine differences among the means of two or more groups on a variable. The independent variables are usually nominal, and the dependent variable is usual an interval.

ANalysis Of VAriance is a family of methods used to perform statistical analysis on experimental results.

analysis of variance; a statistical technique that analyzes the contribution to an experimental result made by independent variables.

Analysis of Variance A statistical method to compare the mean question of interest between several groups.

Analysis of variance. A parametric method used for hypothesis testing (i.e. to determine if statistically significant differences in a response occur among two or more groups).

Analysis of the variance; a group of statistical procedures

Univariate analysis of variance (ANOVA) is a statistical technique to determine, on the basis of one dependent measure, where samples come from populations with equal means. ANOVA is robust to violations of this assumption, however (Lindman, 1974). Univariate analysis of variance employs one dependent measure, whereas multivariate analysis of variance compares samples based on two or more dependent variables (Hair et al., 1995).

Analysis of Variance. Technique used to measure the statistical difference of two or more variables.
