"No, the SAT is not Required." More Colleges Join Test-Optional Train

Is it really saying on page 17 and in Appendix A 42 that the #1 correlation with 4 year graduation rates is “Sex: female” (above grades a lot of other factors) I guess I am not surprised but it is painful to see.

Note that the coefficient variables in the table have not been rescaled to a consistent SD. Instead GPA is range 0-8, SAT is range 20-160, and Gender is range 0-1. This makes it difficult to compare them. A more meaningful measure is the percent of variation explained in 6-year graduation by the criteria</p>

<p>GPA only – 13.5% of variance explained
GPA+SAT – 16.8% of variance explained
GPA+SAT+Gender – 17.1% of variance explained</p>

<p>Gender adds little to the accuracy of the prediction, and the little is does add likely relates to correlations between gender and major selection.</p>
