Mean; 90% CI Inferencea
Age (years) 22.1 ± 2.5 22.9 ± 3.5 .8; ± 2.7 trivial
Height (m) 1.79 ± .06 1.82 ± .06 3.0; ± 5.4 small ↑
Weight (kg) 70.0 ± 6.6 78.0 ± 8.6 8.1; ± 6.8 moderate ↑**
Body fat (%) 8.7 ± 2.5 8.2 ± 3.4 -.6; ± 2.6 small ↓
EA (h/week) 13.9 ± 4.0 9.9 ± 1.9 -4.0; ± 2.9 large ↓***
EA – self-reported intentional exercise activity per week.
aMagnitude thresholds (for difference in means divided by average SD): <0.20, trivial; 0.20-0.59, small; 0.60-1.19, moderate; 1.20-2.00, large. Asterisks indicate effects clear at the 90% level and likelihood that the true effect is substantial, as follows: *possible, **likely, ***very likely, ****most likely. No asterisks mean that 90% CL overlapped the thresholds for substantiveness (unclear difference).
