For example, it is possible to study the effects of political campaign expenditures on voting outcomes. The main goal for an applied econometrician is to turn qualitative data into something quantitative. Economic generalisations describe the laws or statements of tendencies in various branches of economics such as production, consumption, exchange and distribution of income. At this stage, econometricians would define variables found in the economic model and the relationship between different variables. It gives a gentle Examples: State the H 0 and H 1 for each case.
