scaled from zero to some large amount
Unipolar

Bipolar
In order for mathematically derived factors to have psychological meaning, the axes on which the scores are plotted are usually _______ into a specific mathematical relationship with each other
turned or rotated
ROTATION/METHOD

Oblique
usually results in only a FEW meaningful traits
