The "stems" of 9 and 10 indicate scores which are 90 or higher...

Look at the entries for the stem of 9: 9 | 0 1 5 5 5 6 8
These entries represent scores of 90, 91, 95, 95, 95, 96, 98

There's also a "stem" of 10, which with the "leaf" 0, represents a score of 100


Ok...we have these scores which are 90 or higher: 90, 91, 95, 95, 95, 96, 98, 100
