The data stem from the large-scale assessment study PISA 2009
 (Organisation for Economic Co-Operation and Development, 2010) where
 competencies of 15-year-old students in reading, mathematics, and science
 are assessed using nationally representative samples in 3-year cycles. In
 this example, data from the student background questionnaire from the
 Australian sample of PISA 2009 were used. Only data of students with complete
 responses (N = 1,069) were considered.
