Among Hispanics, there is little change in popularity from a grade point average of 1 through 2.5. After 2.5, the gradient turns sharply negative. A Hispanic student with a 4.0 grade point average is the least popular of all Hispanic students, and has 3 fewer friends than a typical white student with a 4.0 grade point average.
