Graduation rates between low income and high income students, controlling for SAT scores. New York Times Magazine

For example: students from families in the top income quartile earn a four-year degree by the age of 24 at higher rates than students from families in the lower income quartile. This is illustrated by looking at the line graph and seeing the gap between the two lines. Notice now that is true at each of the four levels of SAT scores.
