AVERAGE-MARGINAL RELATION

A mathematical connection between a marginal value and the corresponding average value stating that the change in the average value depends on a comparison between the average and the marginal. This mathematical relation between average and marginal surfaces throughout the study of economics, especially production (average product and marginal product), cost (average total cost and marginal cost), and revenue (average revenue and marginal revenue). A similar relation is that between a total value and the corresponding marginal value.
