NON-RANDOM SAMPLE

Statistics Directorate    
French Equivalent: Échantillon non aléatoire

Definition:
A sample selected by a non-random method. For example, a scheme whereby units are selected purposively would yield a non-random sample. Again, a sample obtained by taking members at fixed intervals on a list is a non-random sample unless the list was arranged in a random order.
