This section provides an overview of sampling methods used in qualitative and sometimes quantitative research.
Samples, including sizes, which, in qualitative research, may or may not be fixed prior to data collection, depend on the resources and time available, as well as the study’s objectives. Sampling decisions made need to be carefully made and justified, and explained in the methodology.
Sampling is the key to good qualitative inquiry....Just as the fisherman cats their lines into likely fishing holes, rather than randomly select places to fish, so qualitative researchers deliberately select participants for their studies (Richards and Morse, 2007).
In qualitative research, a good participant is someone who ‘has the knowledge and experience the researcher requires, has the ability to reflect, is articulate, has the time to be interviewed, and is willing to participate (Morse, 1994, p 228).
