Mar 12, 2026 · Purposive sampling is used only in quantitative research, while random sampling is used in qualitative research. Quota sampling specifies participant numbers with certain characteristics, while purposive sampling selects individuals based on their relevance to the research. It emphasizes the importance of selecting appropriate methodologies and sampling techniques to ensure the rigor and relevance of qualitative studies, highlighting various approaches such as ethnography, phenomenology, and decolonizing methodologies. Researchers must clearly define the criteria for selection to ensure relevance. Non-probability sampling methods, such as convenience sampling, purposive sampling, and snowball sampling, are often employed in qualitative research when the goal is to obtain in-depth, contextual understanding. For instance, a study on the impact of technology in classrooms may focus on teachers from urban schools with access to digital tools, ensuring that the sample accurately represents the demographic of interest.
