Types of Purposive Sampling Methods

Research students mostly uses a non-probability sampling technique which is used for both qualitative and quantitative research and is also called purposive sampling. It is a very effective tool that helps students while studying a specific cultural domain. Under this technique, researchers are obliged to rely on their own judgment, especially when choosing the population members to participate in their surveys. So, we can say that this sampling technique is selective, judgmental, and subjective. For this, you need to be equipped with-

· Have prior knowledge about the purpose of the study.

· You can either select or approach participants for the survey.

· You can conduct your survey online to select a particular group of people, the ones who match the desired profile.

· Those sampling techniques where the units are investigated based on the judgment of the researcher must be focused well.

Purposive sampling

Purposive sampling occurs when a group of various non-probability sampling techniques that majorly depend on the researcher’s judgment to select the units such as events, cases, people, data, or organization is studied. Here, the amount of sample is a bit smaller in comparison to probability sampling techniques. Purposive sampling does not entertain arbitrary units from a population in order to create a sample report to generalize information like statistical inferences.

The primary goal of purposive sampling is-

· To be able to focus on the particular characteristics of a population.

· With the help of purposive sampling, the researcher gets to examine the best research method and is able to discover the answer to his research question.

· It also helps the researchers to gather a lot of information based on the data they have collected.

· Researchers get to describe how the population is being affected by the findings.

· The purpose of the method might vary depending upon the type of purposive sampling technique used.

Types of purposive sampling

Purposive sampling bestows a wide range of techniques that helps researchers collect information. Some of which are-

Homogenous sampling

This includes a small homogenous group of units or subjects that are further analyzed or examined in the research process. The main aim of the sampling is to achieve a homogenous sample whose units share similar traits or characteristics.

Critical case sampling

This kind of sampling is used in exploratory qualitative research. In order to identify critical issues, one must determine the dimensions that make the case critical for research. You can also use it to test a hypothesis by selecting a case that permits logical deductions.

Total population sampling

The total population sampling technique is used to examine the entire population with some specific traits or characteristics such as the current pandemic situation, exposure to an event, or some particular experience. Under this technique, the entire population is chosen for examination because the size of the population that has a particular set of traits that you are interested in is minimal.

Expert sampling

In order to glean knowledge from individuals or groups that have particular expertise in specific research is called expert sampling. This kind of sampling is used when you need opinions or thoughts on some assessment with people who have a high degree of knowledge about the study.

Maximum variation sampling

Here you need to collect a wide range of participants with different viewpoints so that you are able to study a particular phenomenon. This helps you cover common themes. The central idea of maximum variation sampling is that it helps gather broader and deeper insight into a phenomenon from all possible points of view and perspectives. With the help of this technique, you get to identify the basic and common themes that are evident across the sample.

Deviant case sampling

This makes you focus on rare or unusual cases. You get to highlight the senses that have notable outcomes. Students are able to make an exciting impression before their teachers with the help of this technique as it helps contribute something unique to their disciplines.

So, these were some of the major types of purposive sampling techniques that students can use in their research. Apart from this, if you ever need help regarding your academic papers or assignments, feel free to contact our online assignment writing services for professional help and guidance.
