VADeaths
Details

The death rates are measured per 1000 population per year. 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.

This provides a rather nice 3-way analysis of variance example.

Format

A matrix with 5 rows and 4 columns.
