Economic Science
In this lesson you'll see why and how the scientific method is a process of discovery. You'll see that it's a process of building theories to explain the workings of the world (the economy) by proposing then testing hypotheses. The five units making up this lesson will guide you through the basics of the scientific method and how it's used in the study of economics. - The first unit, The Method, introduces the scientific method, especially its' four key components -- theories, principles, hypothesis, and data.
- The second unit, Theory, then takes a closer look at theories, including the central role played by abstraction.
- In the third unit, Verification, we focus on the process of verification -- how and why hypothesized relationships about the workings of the economy are compared with actual data.
- We then turn out attention in the fourth unit, Science and Practice, to a simple example of how the scientific method is used to test a hypothesized relation between course grades and where students are seated in a classroom.
- The fifth and final unit in this lesson, Cause and Effect, examines the role that cause and effect plays in the scientific method and economic science.

AVERAGE REVENUE CURVE, PERFECT COMPETITION A curve that graphically represents the relation between average revenue received by a perfectly competitive firm for selling its output and the quantity of output sold. Because average revenue is essentially the price of a good, the average revenue curve is also the demand curve for a perfectly competitive firm's output.
