What is Purposive sampling in Qualitative Research?

When using a variety of non-probability procedures, purposive sampling in qualitative research is carried out for the group of subjects the researcher chooses for the study.

Kinds of Purposive Sampling You Need to Be Aware of

There are many different kinds of purposive sampling in qualitative research. To have proper knowledge to incorporate in the research, you must be aware of all its varieties.

Maximum Variation Sampling

This technique is employed to gather diverse individuals with varying perspectives to investigate a specific subject. The subjects are unusual and include various topics, from common to uncommon knowledge. Largely community-like behaviours, features, experiences, events, incidents, and qualities are displayed in the research of this category. One of the main goals of maximum variation sampling is to obtain all points of view and a better, more comprehensive understanding of a subject.

Homogeneous sample

In this kind of sample, every potential client you have chosen has the same or comparable characteristics, such as the same age, gender, and place of employment. It differs from maximum variation sampling, though. Thus, choose a limited set of units to look over and evaluate when conducting your study.

Deviant or Extreme Case Sampling

This technique is used when investigating a unique and uncommon case. As many have said, it should be extraordinarily unique and out of the ordinary. Cases of this kind provide important details about a certain topic.

Critical Case Sampling

This purposive sampling technique requires gathering small samples that provide precise data. You are not required to conduct an in-depth study. They must sample any significant examples when the reader needs to know a crucial piece of information.

Typical Case Sampling

This method allows you to examine a trend while considering either high- or average-level members of the impacted community. For example, if the education curriculum impacted the average student, you would concentrate on the typical student population.

Whole Population Sampling

As the name suggests, this method provides the researcher with surveys for the population under study. 

Before writing the assignment on purposive sampling, you should be aware of these types of qualitative research.
