purposive sampling
type: Concept
definition: Purposive sampling in qualitative inquiry is the deliberate seeking out of participants with particular characteristics, according to the needs of the developing analysis and emerging theory. Because, at the beginning of the study, the researcher does not know enough about a particular phenomenon, the nature of the sample is not always predetermined.
