Quota Sampling

The sample is drawn according to predefined control characteristics (e.g. gender, age, income), so that it reflects the structure of the population proportionally. The objects are usually selected at random — but they must fulfill the quota plan.

Gender — male	48	48	480
female	52	52	520

Age — 18–30	27	27	270
