Advantages and disadvantages of purposive vs convenience sampling?

Purposive sampling and convenience sampling are two widely used sampling techniques. Purposive sampling involves selecting participants based on a specific criterion, while convenience sampling involves selecting participants based on their accessibility and willingness to participate. The advantage of purposive sampling is that it ensures a representative sample for a particular purpose, but the drawback is that it can be biased towards a specific group. On the other hand, convenience sampling is a quick and easy way to collect data, but it may not accurately represent the population of interest, leading to biased results. Overall, the choice between purposive and convenience sampling depends on the research question and the resources available to obtain a representative sample.
