Analysis of variance (ANOVA)
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 variation.
In other
words,
Analysis of variance (ANOVA) is the process of partitioning and decomposing total variation contained in the data into
various independent components, each of which is attributed to an identifiable
cause or sources of variation and a further component due to chance factor.
