A key element in developing ideas associated with statistical inference involves developing concepts of sampling. The characteristics of studentsâ€™ constructions of the concept of sample were studied through interviews of 62 students in Grades 3, 6, and 9. Six categories of understanding were identified; these categories should prove useful to teachers who want to help students develop appropriate understandings of how a sample must represent a population.
