Definitions for "Analysis of variance"
a statistical technique by which the results of an observation or experiment are analyzed to determine the relative contributions of the different possible causative factors or variables to the outcome. Abbreviated ANOVA.
(ANOVA) a basic statistical technique for analyzing experimental data. It subdivides the total variation of a data set into meaningful component parts associated with specific sources of variation in order to test a hypothesis on the parameters of the model or to estimate variance components. ANOVA is used to test whether the means of many samples differ but it does so using variation instead of mean. It compares the amount of variation within the samples to the amount of variation between the means of samples. If the 'between variation' is significantly larger than the 'within variation', we conclude that the mean of our response has changed. Click here for more.
A statistical method used to determine whether a relationship exists among two or more variables by formulating concurrent comparisons of the variables.
The partitioning of total sum of squares into the sum of squares explained by the model and the remaining sum of squares unexplained.
