| Criterion | Picking all cases that meet some criterion, such as all children abused in a treatment facility. Quality assurance. |
| purposeful | A type of non-random sample in which respondents are specifically sought out. Contrasts with random and convenience samples. A special type of purposive sample is the maximum variation sample. |
| maximum variation sampling | Also called a maximum diversity sampling. A type of purposive sampling in which respondents are chosen to be as different as possible from one another. |
| intensity | Information-rich cases that manifest the phenomenon intensely, but not extremely, such as good students/poor students, above average/below average. |
| homogeneous | Focuses, reduces variation, simplifies analysis, facilitates group interviewing. |
| snowball | Identifies cases of interest from people who know people who know people who know what cases are information-rich, that is, good examples for study, good interview subjects. |
| random purposive | (still small sample size) Adds credibility to sample when potential purposeful sample is larger than one can handle. Reduces judgment within a purposeful category. (Not for generalizations or representativeness.) |
| critical case | Permits logical generalization and maximum application of information to other cases because if it's true of this once case it's likely to be true of all other cases. |
| typical case | Illustrates or highlights what is typical, normal, average. |
| Extreme case | Learning from highly unusual manifestations of the phenomenon of interest, such as outstanding success/notable failures, top of the class/dropouts, exotic events, crises. |
| Negative case | (cases which go against your expectation, not necessarily giving negative views on a subject |
| opportunistic | Following new leads during fieldwork, taking advantage of the unexpected, flexibility. |
