Sampling in qualitative research
What is involved in “purposive sampling” for grounded theory?
Using a random numbers table to select a representative sample of people
Strategically selecting respondents who are likely to provide relevant data
Deciding on a sampling strategy early on and pursuing it relentlessly
Sampling units of time rather than individual persons
Strategically selecting respondents who are likely to provide relevant data
Qualitative researchers often use purposive samples rather than random, probability samples, in order to develop a grounded theory. This typically involves selecting additional participants on the basis of the ideas and concepts that emerge as the project progresses, and it ensures that the researcher gathers data that is relevant to their research questions. Consequently, it is better to start out by choosing members of a sample “purposely”, deliberately, in other words, rather than randomly.
