Average number of students at a school who were in our study and taking a BSc was 16.4 (SD 17.6; median 9; interquartile range 6-24; range 1-70), and number not taking a BSc was 35.6 (SD 21.2; median 36; interquartile range 18-49; range 1-79).

Size of points is proportional to number of students at school
