In one-way ANOVA, the amount of total variation that is unexplained is measured by:

A) the sum of squares for treatments
B) the sum of squares for error
C) the total sum of squares
D) the degrees of freedom
E) none of these

Total Variation

The overall measure of the spread or dispersion within a set of data points or observations.

Sum of Squares

The total squared deviation of each observation from the mean, a measure of total variation within a dataset.

Unexplained

Refers to the portion of variance in a set of data that cannot be accounted for by the predictive variables in a statistical model.
