Weight loss after four months with/without a financial incentive
A dataset with 36 observations on the following 2 variables.
WeightLoss | weight loss (in pounds) after 4 months |
Group | Treatment group: Control or Incentive |
Researchers investigated whether financial incentives would help people lose weight more successfully. Some participants in the study were randomly assigned to a treatment group that was offered financial incentives for achieving weight loss goals, while others were assigned to a control group that did not use financial incentives. All participants were monitored over a four month period and the net weight change (Before - After in pounds) at the end of this period was recorded for each individual. Then the individuals were left alone for three months with a followup weight check at the seven-month mark to see whether weight losses persisted after the original four months of treatment. This dataset has only the non-missing 4-month data. The 7-month data are in WeightLossIncentive7 and both measurements (including missing values) are in WeightLossIncentive.
