In the case of purposive sampling, the people are chosen from a particular background. There is cautious time and efforts taken to understand the participant. The purposive sampling methodology is a form of sampling technique where the researcher decides to rely on their judgement to choosing participants from a population for the purpose of understanding their objective sin the story. This is a form of non-probability sampling method. This is found to be a cost effective method of assessing the people for research. This technique is esp. useful in the anthropological studies of human behaviour and patterns. They help understanding the issues form the perceptive of the participants. The purpose of using this technique is not to judge or gauge the views of the participant. Rather it is a method of analyzing the reason that the people of a particular sector choose to believe a certain ideology or framework. These are many advantages and disadvantages in this process. They are probed in detail in the following. The advantages of this research design are that the issues and the related subjects that are not considered in this initial analysis can be evaluated in detail. The interviews are not a survey questions some of these are open ended questions. These are created for the situation that is not limited to particular questions. There can be the framework and detailed in interpretations of the research can be done.
The nuances of human emotions are compelling and the nuances can be understood from a comprehensive perspective. The data is gathered from few individuals to gain perspective in detail. The limitation of this research is dependent on the knowledge of the researcher. There is a tendency for the participants to emulate the needs of the researcher and answer questions that they feel would satiate the research. There should be careful analysis of the people and the personal quirky behaviour to understand. Innate beliefs of the researcher should be hidden and a neutrality stand should be taken by the people. There should be no rigid approach that the researcher must take while analyzing the nuances. The quantity of data makes interpretation difficult; hence, the researcher must utilize other forms of research data to bolster the findings. It would become difficult to take a stand when a research is conducted. The researcher should take efforts to prove the credibility of the resources used and its relevance. It becomes difficult for the researcher to prove the veracity of the data. The ways in which the researcher had taken a stand to reduce ambiguity should be explained and elucidated in detail. The process can be time consuming to prove the credibility of the resources. The data that is found might not be accepted in the scientific community given these limitations. The researcher should ensure that there is proper and nuanced detail in analyzing the data to prove the claims that is derived in the research.
