Using a unique scoring index from zero to to calculate a student's sleep regularity, students with very irregular sleep patterns were given lower scores close to zero, while more regular sleepers were given higher scores close to The researchers found that for every score increase of 10 on the regularity index, the student had an average increase of 0.
