PROC FACTOR is run with ROTATE=VARIMAX. What is the purpose of Varimax rotation?
Select an answer to reveal the explanation.
Short Explanation and Infographic
Here's the deal — b is correct because Varimax is an orthogonal rotation that pushes each loading toward either 0 or 1, making it clearer which variables load on which factors (simple structure). A describes what unrotated PCA does.

Full Explanation
B is correct because Varimax is an orthogonal rotation that pushes each loading toward either 0 or 1, making it clearer which variables load on which factors (simple structure). A describes what unrotated PCA does. C describes oblique rotations like PROMAX. D describes factor count selection, not rotation.
