SSy is the total variation in Y, SSx is the variation in Y explained by the regression, and SSerror is the variation in Y not explained by the regression. Therefore, SSy can be decomposed into SSx and SSerror. SSbetween is the variation in Y between the groups, and SSwithin is the variation in Y within the groups. Therefore, SSy can also be decomposed into SSbetween and SSwithin.
