Quota Sampling
A market research method where researchers select participants to fill specific quotas based on age, gender, income, etc.
Quota sampling is faster and cheaper than random sampling but can introduce bias if quotas are poorly set. It is widely used in marketing research when time or budget is limited.
It's like making sure your focus group has exactly the right mix of people so the results actually represent your customers.
Real world: A streaming service wants feedback on a new show. It sets quotas: 40% aged 18-24, 30% 25-34, etc. Researchers then find people who fit those quotas rather than picking randomly.
💡 Quota sampling makes research faster and more targeted — but it only works if your quotas are smart.
