Which of the following is an example of using the scientific method with a natural experiment? a. measuring how long it takes a marble to fall from a ten story building b. comparing plant growth with and without a soil additive c. tracking the price of oil when a war in the Middle East interrupts the flow of crude oil d. observing the reaction when two chemicals are mixed together 10. The goal of an economist who formulates new theories is to a. provide an interesting framework of analysis, whether or not the framework turns out to be of much use in understanding how the world works. b. provoke stimulating debate in scientific journals. c. contribute to an understanding of how the world works. d. demonstrate that economists, like other scientists, can formulate testable theories. 11. Suppose an economist develops a theory that higher food prices arise from higher gas prices. According to the scientific method, which of the following is the economist’s next step? a. Collect and analyze data. b. Go to a laboratory and generate data to test the theory. c. Publish the theory without testing it. d. Consult with other economists to see they agree with the theory. 12. Which of the following statements applies to economics, as well as to other sciences such as physics? a. Experiments are considered valid only when they are conducted in a laboratory. b. Good theories do not need to be tested. c. Real-world observations often lead to theories. d. Economics, as well as other sciences, is concerned primarily with abstract concepts. 13. With respect to how economists study the economy, which of the following statements is most accurate? a. Economists study the past, but they do not try to predict the future. b. Economists use “rules of thumb” to predict the future. c. Economists devise theories, collect data, and analyze the data to test the theories. d.
