Concept explainers
To describe how undercoverage might lead to bias in this study and explain the likely direction of the bias.
Explanation of Solution
The director of the student life at a small college wants to know what percent of students eat regularly in cafeteria. For this the director selected the students who lives in the dorms. This results in undercoverage as the survey includes only the students who lives in dorms and not the other categories of students. And the students who lives in dorms does not represent the students at the college so the data studied is a bias one. This does not gives the true result of the population at the college. This survey will explain only the eating habits of the dorms students only.
