Definitions:

ANOVA Table

A structured display that sums up the sources of variability in a dataset, used primarily in analysis of variance to discern significant differences between means.

Sum of Squares

The total of the squared differences between data points and their mean, reflecting the total variation within a data set.

Error Sum of Squares

A measure of the discrepancy between the data and an estimation model, quantifying the amount of variation in the data that is not explained by the model.

F-Test Statistic

A statistical measure used primarily in ANOVA and regression analysis to evaluate the significance of groups of variables, determining whether variances between sample means are greater than the variance within the samples.
