They are cross-classified by age group (rows) and population group (columns). The age groups are: 50–54, 55–59, 60–64, 65–69, 70–74 and the population groups are Rural/Male, Rural/Female, Urban/Male and Urban/Female. </p> <p>This provides a rather nice 3-way analysis of variance example. </p> <h3>Source</h3> <p>Molyneaux, L., Gilliam, S.
