Televisions, Physicians, and Life Expectancy

Televisions, Physicians, and Life Expectancy

This article, created by Allan Rossman of Dickinson College, describes a dataset on life expectancies, densities of people per television set, and densities of people per physician in various countries of the world. The example addresses correlation versus causation and data transformations. The author states that "the example has proven very useful for helping students to discover the fundamental principle that correlation does not imply causation."
