Question

Purposive sampling involves selecting participants based on specific criteria that are relevant to the research question. Quota sampling involves setting quotas for certain demographic categories and selecting participants until the quotas are filled. Convenience sampling involves selecting participants who are easily accessible and available to participate. These types of nonprobability sampling may be appropriate when the population of interest is difficult to define or access, or when resources are limited. However, they also introduce potential biases into the sample and may limit the generalizability of the findings.
