Recent research (Page & Feifs, 1985; Powell & Steelman, 1984; Steelman & Powell, 1985) attempts to draw inferences about the relative standing of the states on the basis of mean SAT scores. These papers point out that this cannot be done without statistically adjusting for various differences among the states. In this paper I identify five serious errors that, when made, call into question the validity of such inferences. In addition, I describe some plausible ways to avoid the errors.
