Note: Private school is an indicator variable that denotes if a student attended a private or religious high school. Duke admissions office rank variables take values between 1 and 5. The variable SAT also includes ACT scores that were converted to the SAT scale. If the missing SAT values were imputed, the regression results (presented in the following sections of this paper) would not change. The total number of observations is conditional on having information on Duke Admissions Office Rank.
