C

Answer to Question 2

The scientific method is the name for the ongoing process that economists and other scientists use to develop models of the world, test those models with data and evaluate how well they predict or describe behavior. While this process may not reveal the true' model of the world, it does help in identifying models that are useful in understanding the world.
In order to decide whether models make accurate predictions or not, economists test them against real-world data. Data are facts, measurements, or statistics that describe the world. This process of testing models against data is called empiricism.
