What type of sampling is often used in qualitative research?

Purposive sampling is often employed in qualitative research because it allows researchers to select participants based on specific characteristics or criteria that are relevant to the study's objectives. This method ensures that the sample consists of individuals who possess particular insights or experiences that will enrich the data and contribute to a deeper understanding of the phenomenon being investigated.

Unlike random sampling, which aims to produce a representative sample of the larger population, purposive sampling focuses on obtaining information-rich cases that can provide in-depth perspectives. This is essential in qualitative research, where the goal is often to explore complex social processes or individual narratives rather than to generalize findings to a broader population.

Convenience sampling, while sometimes used in qualitative contexts, tends to rely on participants who are readily accessible, which may limit the diversity of insights gathered. Stratified sampling, on the other hand, is more common in quantitative research, where it ensures representation across predefined subgroups within the population, making it less suitable for the exploratory nature of qualitative studies. In summary, purposive sampling directly aligns with the aims of qualitative research, emphasizing targeted selection to deepen understanding rather than representativeness.
