There are several types of nonprobability (nonrandom) sampling designs. Each addresses a different research need. The five nonprobability sampling designs described in this textbook are (1) convenience sampling, (2) quota sampling, (3) purposive or purposeful sampling, (4) network or snowball sampling, and (5) theoretical sampling. These sampling methods are applied in both quantitative and qualitative research. However, convenience sampling and quota sampling are applied more often in quantitative, outcomes, and intervention research than in qualitative studies and are discussed in this section.
