Types of purposive sampling techniques with their examples and application in qualitative research studies.
Abstract
The aim of the article was to review the purposive sampling types as discussed
by Patton (1990) and exemplify them in line with the current trends in the studies being
conducted today. The sixteen purposive sampling techniques discussed include extreme case
sampling, deviant case sampling, Intensity sampling, maximum variation sampling,
homogeneous sampling, typical case sampling, stratified purposeful sampling, critical case
sampling, snowball or chain sampling, criterion sampling, theory-based sampling,
opportunistic sampling, random purposeful sampling, sampling politically important cases,
convenience sampling and mixed purposeful sampling. The article has further guided on
how these are used in different topics to enable upcoming researchers be able to apply them
responsibly and effectively in their studies.
