On this Picostat.com statistics page, you will find information about the WeightLossIncentive7 data set which pertains to WeightLossIncentive7. The WeightLossIncentive7 data set is found in the Stat2Data R package. Try to load the WeightLossIncentive7 data set in R by issuing the following command at the console data("WeightLossIncentive7"). This may load the data into a variable called WeightLossIncentive7. If R says the WeightLossIncentive7 data set is not found, you can try installing the package by issuing this command install.packages("Stat2Data") and then attempt to reload the data with library("Stat2Data") followed by data("WeightLossIncentive7"). Perhaps strangley, if R gives you no output after entering a command, it means the command succeeded. If it succeeded you can see the data by typing WeightLossIncentive7 at the command-line which should display the entire dataset.
If you need to download R, you can go to the R project website. You can download a CSV (comma separated values) version of the WeightLossIncentive7 R data set. The size of this file is about 507 bytes.
Weight loss after seven months with/without a financial incentive
A dataset with 33 observations on the following 2 variables.
| Treatment group:
| Weight loss (in pounds) after seven months
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.
