This exercise poses two related questions that might form the basis of a statistical study. Tell how the two questions differ and how these differences would affect the goal of a study and the design of the study.
First question: How often do high school students attempt suicide?
Second question: How often are suicide attempts made by high school students?
◦ The first question involves a study of people who attempt suicide. The second question involves a study of high school students in general. The first question would be addressed by surveying all those who attempt suicide, a group that would be difficult to survey. The second question might be addressed by surveying high school students.
◦ The first question involves a study of high school students in general. The second question involves a study of those who attempt suicide. The first question might be addressed by surveying high school students. The second question would be addressed by surveying people who attempt suicide, a group that would be much more difficult to survey.
