1. Defining the Target Population: Identify the population that the study aims to represent. This includes understanding the distribution of key demographic variables. 2. Setting Quotas: Based on the target population, set specific numerical targets for each subgroup. This may involve using national census data or other reliable sources to determine the proportions. 3. Sampling Methods: Implement sampling methods that help achieve the set quotas. This may include stratified sampling, where the population is divided into strata, and samples are drawn proportionally from each stratum.
