BIASED SAMPLE

Statistics Directorate    
French Equivalent: Échantillon avec erreur systématique

Definition:
A sample obtained by a biased sampling process, that is to say, a process which incorporates a systematic component of error, as distinct from random error which balances out on the average. Non-random sampling is often, though not inevitably, subject to bias, particularly when entrusted to subjective judgement on the part of human being.
