YES
The question resolves to yes if the 'outcome based' group has a greater weight proportion with >5% loss at six months than the 'goal-directed group' and no if the 'goal-directed group' had a greater loss. Outcome-based group: can earn up to $750 by losing weight over 6 months. Goal-directed group: can earn up to $750 by wearing a Fitbit and doing exercise, joining and participating in weight watchers etc over 6 months. If the difference is not statistically significant, resolves to NA. Sample: 668 obese adults, randomised to 3 groups (control group excluded from this question).
