Question

A researcher wants to study regional differences in dental care. He takes a multistage sample by dividing the United States into four regions, taking a simple random sample of ten schools in each region, randomly sampling three classrooms in each school, and interviewing all students in those classrooms about whether they’ve been to a dentist in the previous year. Identify each stage of this sampling design, indicating whether it involves stratification or clustering.
