Answer explanation
This survey exhibits undercoverage bias because it relies on voluntary participation and targets students who are active in fitness-related social media groups. As a result, students who are less interested in fitness or do not actively engage with these platforms are less likely to respond, leading to an overrepresentation of students who are already interested in exercise and potentially skewing the results to reflect higher levels of activity than the general student population.

Scenario & Question
What percent of Americans wash their hands after using the bathroom? It depends on how you collect the data. In a telephone survey of 1006 U.S. adults, 96% said they always wash their hands after using a public restroom. An observational study of 6028 adults in public restrooms told a different story: Only 85% of those observed washed their hands after using the restroom.
Explain why the results of the two studies are so different.

Scenario & Question
Three hundred people participated in a free 12-week weight-loss course at a community health clinic. After one year, administrators emailed each of the 300 participants to see how much weight they had lost since the end of the course. Only 56 participants responded to the survey. The mean weight loss for this sample was 13.6 pounds.
Describe how nonresponse might lead to bias in this study. Is the mean amount of weight loss in the sample likely to be greater than or less than the mean for all 300 participants in the course?
