Econometrics is the application of statistical methods to economic data and is described as the branch of economics that aims to give empirical content to economic relations. More precisely, it is “the quantitative analysis of actual economic phenomena based on the concurrent development of theory and observation, related by appropriate methods of inference”. An introductory economics textbook describes econometrics as allowing economists “to sift through mountains of data to extract simple relationships”. The first known use of the term “econometrics” (in cognate form) was by Polish economist Paweł Ciompa in 1910. Jan Tinbergen is considered by many to be one of the founding fathers of econometrics. Ragnar Frisch is credited with coining the term in the sense in which it is used today.

The basic tool for econometrics is the multiple linear regression model. Econometric theory uses statistical theory and mathematical statistics to evaluate and develop econometric methods. Econometricians try to find estimators that have desirable statistical properties including unbiasedness, efficiency, and consistency. Applied econometrics uses theoretical econometrics and real-world data for assessing economic theories, developing econometric models, analyzing economic history, and forecasting..

- Econometrics – application of mathematics and statistical methods to economic data
- Mathematical economics – application of mathematical methods to represent economic theories and analyze problems posed in economics.
- Economic statistics – topic in applied statistics that concerns the collection, processing, compilation, dissemination, and analysis of economic data.
- Time series – sequence of data points, measured typically at successive time instants spaced at uniform time intervals.
