There is considerable intra-individual variability in the students' physical activity, which accounts for 67-83% of the overall variability, depending on the study group. Unadjusted, single-day distributions are much wider and have more weight in the tails than model-adjusted distributions, due to this large intra-individual variability in the data.

Efficiency Meets Impact.
That's Progress Together.
