JUDGEMENT SAMPLE

Statistics Directorate    
French Equivalent: Échantillon au jugé

Definition:
In the terminology of Deming (1947) a judgement sample is, in general, any sample which is not a probability sample.

Context:
The dichotomy is not, perhaps, perfect; for example, the visible stars of the sky are not a “probability sample” of the matter in the universe, nor does it appear proper to describe them as a “judgement sample”. It seems best to confine this term to the case where some element of human judgement enters directly into the selection of the sample.
