Popular sampling strategies in qualitative research:
Convenience sampling – participants are readily available, but associates of the sample may not be best respondents.
Purposive sampling – advisedly selects those who are acceptable to accept best to say.
Snowball sampling – allows alternative of acceptable candidates from difficult to ability groups.
Generalizability: The aim of qualitative analysis is not to generalize, it still charcoal a limitation of the approach. We cannot booty a accumulation of people’s angle and administer them to addition context, addition abode or addition accumulation of people. We may apprehend them and anticipate ‘Yes! This sounds accustomed to me!’ or ‘I am afraid at these findings!’ but we cannot, then, extrapolate from them and adjudge that we accept adamantine affirmation that can be activated in alternative contexts

Obviously the ambition in accepting this sample is for it to be as abundant like the absolute citizenry as possible. This is of advance of the absolute accent to the generalizability of the study.
Generalization agency that the after-effects of the analysis performed on the sample can again be affected or activated to the accomplished ambition population. This can be done to with capricious degrees of accurateness and extensiveness. Grove, Gray, & Burns (2015, pp. 250-251) accompaniment that analysis affection and bendability with alternative analysis allegation can adapt the amount of generalizability; acceptation that with aerial affection research, allegation can be ambiguous from the sample to the attainable population, and again to the ambition population.
