Which sampling method uses quotas to reflect the characteristics of a population?

• A. Quota Sample
• B. Random Sample
• C. Stratified Sample
• D. Convenience Sample

Answer: (A)

The concept being tested is using fixed quotas to reflect the population’s characteristics. In quota sampling, researchers first identify key traits (like age, gender, or region) and set quotas so the sample matches the population proportions for those traits. They then recruit participants specifically to fill those quotas, so the final sample mirrors the population on the chosen characteristics, even though the selection within each quota isn’t random. This differs from a random sample, which aims for equal chance of selection for every member without predefined quotas. It also differs from a stratified sample, which divides the population into strata and samples from each (often randomly within strata) to ensure representation across groups. A convenience sample selects readily available individuals with little regard for representativeness. Therefore, using quotas to reflect population characteristics is quota sampling.
