Categorical IV

Continuous DV

Error V reduced because can control for individual differences.

Error variance-individual differences= RESIDUAL ERROR

Error V: original score-column mean (true score)

Residual Error V: error score-row mean (of error scores!)

• Between groups mean square: true V.
• Residual mean square: residual E. V.
• Within groups mean square: error V.
