Qualitative researchers may start with convenience or snowball sampling, but usually rely on purposive sampling to guide them in selecting data sources that maximize information richness. One purposive strategy is maximum variation sampling, which entails purposely selecting cases with a wide range of variation. Another important strategy is sampling confirming and disconfirming cases—i.e., selecting cases that enrich and challenge the researchers' conceptualizations. Other types of purposive sampling include extreme case sampling (selecting the most unusual or extreme cases); typical case sampling (selecting cases that illustrate what is typical); and criterion sampling (studying cases that meet a predetermined criterion of importance).
