Purposive sampling is a non-probability sample. It is selected based on population characteristics and study objectives. It may be referred to as subjective or selective sampling. It is also known as judgmental sampling. Here are the purposive sampling pros and cons to think about and discuss. List of the Pros of Purposive Sampling. 1.
What Are the Advantages of Purposive Sampling? The main advantage of purposive sampling is that a researcher can reach a targeted sample quickly. It is easy to get a sample of subjects with specific characteristics. Additionally, researchers are able to draw on a wide range of qualitative research
The main disadvantage of purposive sampling is that the vast array of inferential statistical procedures are then invalid. Inferential statistics lets you generalize from a particular sample to a larger population and make statements about how sure you are that you are right, or about how accurate you are.
Advantages of Purposive Sampling Each subtype of purposive sampling has their own advantages and disadvantages. In general, one major advantage of this type of sampling is that it’s easier to make generalizations about your sample compared to, say, a random sample where not all participants have the characteristic you are studying.
Purposive sampling (also known as judgment, selective or subjective sampling) is a sampling technique in which researcher relies on his or her own judgment when choosing members of population to participate in the study.
What Are the Advantages and Disadvantages of Purposive Samples? Purposive samples target a very specific population, which can help gain detailed insight on their characteristics, but a disadvantage is the difficulty in reaching a large sample size. Defining the target for purposive samples can be
There are a number of different types of purposive sampling, each with different goals. This article explains (a) what purposive sampling is, (b) the eight of the different types of purposive sampling, (c) how to create a purposive sample, and (d) the broad advantages and disadvantages of purposive sampling.

Disadvantages of Purposive Sampling. The selection criteria the researcher uses can be very arbitrary and are almost always subjective. The narrowness of the questions used will reflect the researcher’s particular stance on a subject far more than a random sample.
Disadvantages of Purposive Sampling. Researcher bias. The main disadvantage of purposive sampling is the high probability of researcher bias, as each sample is based entirely on the judgment of the researcher in question, who generally is trying to prove a specific point.
What Is Sampling?
Purposive Sampling: where the researcher chooses a sample based on their knowledge about the population and the study itself. The study participants are chosen based on the study’s purpose. There are several types of purposive sampling. For a full list, advantages and disadvantages of the method, see the article: Purposive Sampling.
The Disadvantages of Quota Sampling Sample selection is not random There is a potential for selection bias, which can result in a sample that is unrepresentative of the population
