This course introduces data analysis and econometrics. Econometrics is a collection of methods that use data and statistical techniques to extract information from data, to answer real-world applied questions, and to test predictions of economic theory. Econometrics is used by governments and businesses to study the effects of government policies and to use historical data to forecast future values of variables such as gross domestic product, interest rates, unemployment rates, stock market prices, and sales growth. This course is the first in a sequence on applied economic statistics, econometrics, and data analysis. The focus is on applications and interpreting the findings of applied econometric studies.
