But seriously, three significant figures from 37 people? Shouldn’t be using percentages at all at that level of accuracy.

Discarding the meaningless digits at the end will make it impossible to rank the schools of course, but that should be a clue that you’re ranking things by statistical noise.

That would make him or her the .993 person.
