  Black Student Density Category
0-20 20-40 40-60 60-100
Average Standard error Average Standard error Average Standard error Average Standard error
(Black-White gap accounting for SES) - (Black-White gap)8*1.67*1.95*2.352.5

(Black-White gap accounting for student, teacher, and school characteristics) - (Black-White gap)
11*3.210*3.37*3.66 3.7
*Statistically different from zero (p<=.05).
NOTE: "Black student density" is the percentage of students in a school who were Black (e.g., schools in the 0-20 percent category had a percentage of students who were Black between 0 and 20 percent). Socioeconomic status was measured by a composite score on parental education and occupations, and family income.
