Qualitative research focuses on in-depth inquiry within a specific context through participants' perspectives rather than generalization. Samples tend to be small and purposive rather than representative as many potential participants do not want to participate. Different sampling techniques are used including intensity sampling to study different levels of a topic, homogeneous sampling of similar participants, criterion sampling of those meeting a characteristic, snowball sampling through participant referrals, and random purposive sampling of a subset of a larger purposive sample.

3. qualitative research is characterized
by in-depth inquiry, immersion in
a setting, emphasis on context,
concern with participants’
perspectives, and description of a
single setting, not generalization
to many settings

4. because samples need to be small
and many potential participants
are unwilling to undergo the
demands of participation, most
qualitative research samples are
purposive

5. representativeness is secondary to
the quality of the participants’
ability to provide the desired
information about self and setting

6. Intensity sampling:
selecting participants who permit
study of different levels of the
research topic

7. Homogeneous sampling:
selecting participants who are
very similar in experience,
perspective, or outlook

8. Criterion sampling:
selecting all cases that meet some
pre-defined characteristic

9. Snowball sampling:
selecting a few individuals who
can identify other individuals
who can identify still other
individuals who might be good
participants for a study

10. Random purposive sampling:
with a small sample, selecting by
random means participants who
were purposively selected and are
too numerous to include all in the
study
