Purposive Sampling generalizable or the existence of a particular kind of case will undermine all that you 'know' to be true about a phenomenon, then look for that kind of case." These do not exhaust the possibilities but illustrate some of the strategic lenses through which purposive sampling can be considered. The general principle,

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.
Knowing the advantages and disadvantages of purposive sampling can help you decide if this approach fits your research design.
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.

The focus of this chapter is purposive (or theoretical) sampling to produce credible and trustworthy explanations of a phenomenon (a specific aspect of society). A specific research question (RQ) guides the methodology (the study design or approach). It defines the participants, location, and actions to be used to answer the question.

Jan 30, 2024 · Purposive sampling, also known as judgmental or expert sampling, involves intentional selection of participants based on the researcher’s expertise. Participants are chosen deliberately, not randomly, to align with specific study objectives.
