Quota sampling is a type of non-probability sampling where researchers will form a sample of individuals who are representative of a larger population. The application of quota sampling can be cost-effective. Quota sampling is a non-probability sampling technique that targets a population of interest. It is this second step which makes the technique one of non-probability sampling. Two-stage Proportionate to size (PPS) Cluster Sample with Quota Sampling in the Second Stage: The population is divided into multiple clusters. In this case, as a sample is formed on basis of specific attributes, the created sample will have the same attributes that are found in the total population.

In this step, we analyze our data and choose the traits or characteristics to be chosen for the classification of the data. SamplingSampling refers to the statistical process of selecting and studying the characteristics of a relatively small number of items from a relatively large population of such items,, to draw statistically valid inferences about the characteristics about the entire population. Researchers use quota sampling when random sampling isn't feasible, and they want more control over who they select compared to other non-probability methods, such as convenience sampling. If there is a rule, but not based on probability, the method is purposive. 2. For example interviewers might be tempted to interview those who look most helpful.
