Définition Extrapolation
When extrapolating conclusions are drawn on the development of data based on previously collected data. The conclusions drawn though are not fully hedged.
An example is the extrapolation of election results, shortly after the polls have closed. Here, based on a partial result (votes counted so far), the result of the election is projected. When extrapolating, one usually resorts to extensive experience of the past.
In elections, for example, it is taken into consideration that voters of radical parties rarely openly concede their voting behavior, at least not as often as voters of established parties. Accordingly, these votes are given more weight in an extrapolation.
Excessive extrapolation is not recommended, the results are prone to be unreliable.
