- Purposive sampling is a non-randomized sampling technique that selects sampling units based on certain criteria. Purposive research sampling is a type of non-probability approach in which the researcher chooses a sample (person, cases, or events) based on their assessment that it would fit the study’s objectives.

Purposive sampling is best used when you want to focus in depth on relatively small samples. Perhaps you would like to access a particular subset of the population that shares certain characteristics, or you are researching issues likely to have unique cases. The main goal of purposive sampling is to identify the cases, individuals, or communities ...
Depending on your research objectives, there are several purposive sampling methods you can use: 1. Maximum variation (or heterogeneous) sampling 2. Homogeneous sampling 3. Typical case sampling 4. Extreme (or deviant) case sampling 5. Critical case sampling 6. Expert sampling
Maximum variation sampling, also known as heterogeneous sampling, is used to capture the widest range of perspectives possible. To ensure maximum variation, researchers include both cases, organizations, or events that are considered typical or average and those that are more extreme in nature. This helps researchers to examine a subject from diffe...
Homogeneous sampling,unlike maximum variation sampling, aims to reduce variation, simplifying the analysis and describing a particular subgroup in depth. Units in a homogeneous sample share similar traits or specific characteristics—e.g., life experiences, jobs, or cultures. The idea is to focus on this precise similarity, analyzing how it relates ...
Typical case samplingis used when you want to highlight what is considered a normal or average instance of a phenomenon to those who are unfamiliar with it. Participants are generally chosen based on their likelihood of behaving like everyone else sharing the same characteristics or experiences. Keep in mind that the goal of typical case sampling i...
The idea behind extreme case samplingis to illuminate unusual cases or outliers. This can involve notable successes or failures, “top of the class vs. bottom of the class” scenarios, or any unusual manifestation of a phenomenon of interest. This form of sampling, also called deviant case sampling, is often used when researchers are developing best ...
Critical case samplingis used when a single or very small number of cases can be used to explain other similar cases. Researchers determine whether a case is critical by using this maxim: “if it happens here, it will happen anywhere.” In other words, a case is critical if what is true for one case is likely to be true for all other cases. Although ...
Expert samplingis used when your research requires individuals with a high level of knowledge about a particular subject. Your experts are thus selected based on a demonstrable skill set, or level of experience possessed. This type of sampling is useful when there is a lack of observational evidence, when you are investigating new areas of research...
Purposive sampling is widely used in qualitative research, when you want to focus in depth on a certain phenomenon. There are five key steps involved in drawing a purposive sample.

Jun 18, 2020 · Purposive sampling is ‘used to select respondents that are most likely to yield appropriate and useful information’ (Kelly, 2010: 317) and is a way of identifying and selecting cases that will use limited research resources effectively (Palinkas et al., 2015).

Purposive sampling is a sampling design that is not intended to offer a representative sample but rather to hone in on particular phenomena and/or processes. In their overview of qualitative interviewing, Rubin and Rubin (1995) suggest guidelines for selecting informants purposively.
