Adequacy problem

from Wikipedia, the free encyclopedia

In statistics, the adequacy problem is the difficulty of selecting that data material for statistical analysis that adequately represents the relevant world section or area of ​​reality.

This restriction to the essentials is a problem in any modeling , since a model, by definition, represents a simplified image of reality that is reduced in detail or data volume.

If there is extensive factual agreement through a statistical measure constructed from the statistical data , then one speaks of the adequacy of this measure for the facts to be described. Against the background of limited survey possibilities , the construction of suitable, adequate measures is one of the main problems in official statistics .
