SCIENCE: A discipline, or topic of study, that uses the scientific method to investigate and explain the operation of the world by testing and verifying hypothesized relationships. While the term science is often used in reference to the physical sciences, including chemistry, physics, and biology, it's also relevant to social sciences, including economics, sociology, and political science. The reason is that science is not really a subject, but a method of investigation--the scientific method. The scientific method is uses theories to derived hypotheses which are verified against real world data.

MARGINAL COST The change in total cost (or total variable cost) resulting from a change in the quantity of output produced by a firm in the short run. Marginal cost (MC) indicates how much total cost changes for a given change in the quantity of output. Because changes in total cost are matched by changes in total variable cost in the short run (total fixed cost is fixed), marginal cost is the change in either total cost or total variable cost. It is found by dividing the change in total cost (or total variable cost) by the change in output. Marginal cost is one of four cost concepts used in short-run production analysis. The other three are average total cost, average fixed cost, and average variable cost.
