Document Summary
Interviewing and sampling in qualitative research (lecture 3) Sample for meaning: not about generalizability, we don"t sample for numbers, we sample for meaning. We approach sampling differently than quantitative research. Theoretical (or purposeful: selection of participants based on needs of study: Based on concepts that have relevance to evolving theory. Ex: concepts repeatedly present (or noticeably absent) In paper, mention how you selected your participants. Convenience sampling: get people to participate because it is convenient, usually used by new researchers, we will probably all be using convenience sampling, problem: it is not a purposeful or strategic approach. Snowball sampling (nominated, network: can ask participants if they know someone who would be interested in talking about. Problem x : good to get to population that is hard to reach, problem: it is the participant nominating someone, so you don"t have as much control. Volunteer sampling: people from general public volunteering to be participants, problem: entire population is based on a volunteer.
