An ANOVA table is a tabular summary of an analysis of variance. Its rows identify sources of variation, and its columns ordinarily give the corresponding
degrees of freedom, sums
of squares, mean squares, and test statistics.
For a source having sum of squares 
and 
degrees of freedom, the
mean square is

An 
statistic is a test
statistic formed by dividing an appropriate source mean square by an error mean
square. The statistical model specifies the
assumed relationship between the observations and their sources of variation. The
precise rows and degrees of freedom depend on
this model and on the experimental design.
