Weight loss after seven months with/without a financial incentive


A dataset with 33 observations on the following 2 variables.

Group Treatment group: Control or Incentive
Month7Loss Weight loss (in pounds) after seven months


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 7-month data. The 4-month data are in WeightLossIncentive4 and both measurements (including missing values) are in WeightLossIncentive.
