Do Financial Incentives Improve Weight Loss?
Description
An experiment to see if financial incentives improve weight loss
Format
A dataset with 38 observations on the following 3 variables.
WeightLoss | Weight loss (in pounds) after four months |
Group | Treatment group: Control or Incentive |
Month7Loss | Weight loss (in pounds) after seven months |
Details
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.
The 4-month data alone (with missing values omitted) is stored in WeightLossIncentive4.
The 7-month data alone (with missing values omitted) is stored in WeightLossIncentive7.
