Econometrics literally means 'economic measurement'. It is a combination of mathematical economics, statistics, economic statistics and economic theory.
The two main purposes of econometrics are to give empirical content to economic theory and also to empirically verify economic theory. For example, econometrics could empirically verify if, indeed, a given demand curve slopes downward as economic theory would suggest. Empirical content is also applied, in that a numerical value would be given to this slope, while economic theory alone is usually mute on actual specific values.
Arguably the most important tool of econometrics is regression analysis (for an overview of a linear implementation of this framework, see linear regression).
