difference between quota and random sampling
Best Answer: Quota sampling is a method for selecting survey participants. In quota sampling, a population is first segmented into mutually exclusive sub-groups, just as in stratified sampling. Then judgment is used to select the subjects or units from each segment based on a specified proportion.
Stratified Sampling. Stratified random sampling is a sampling method in which the population is first divided into strata (A stratum is a homogeneous subset of the population). Then a simple random sample is taken from each stratum.
