differential sampling

Definition:
The practice of setting QUOTAS for certain subgroups within a POPULATION out of proportion to their representation within that population e.g. a RANDOM SAMPLE would contain say, 12 per cent over 65 years old but the needs of this segment might be important to the researcher who would set a higher quota for persons in this age group.

Cross-References:
[random sample] [quotas] [sampling]
