Sir, we use qualitative method to understand the experiences and attitudes of patients, the community or health care worker. These methods aim to answer questions about the ‘what’, ‘how’ or ‘why’ of a phenomenon rather than ‘how many’ or ‘how much’, which are answered by quantitative methods. If the aim is to understand how a community or individuals within it perceive a particular issue.
Md. Saidur - Qualitative research methodology is appropriate to answer questions about understanding, experience, meaning and perspective, most often from the standpoint of the participant. It is used to gain an understanding of underlying reasons, opinions, and motivations and provides insights into the problem or helps to develop ideas or hypotheses for potential quantitative research. Qualitative research is appropriate at gaining a deep understanding of a specific organization or event, rather a than surface description of a large sample of a population. These data are usually not amenable to counting or measuring. Qualitative research techniques include ‘small-group discussions’ for investigating beliefs, attitudes and concepts of normative behavior; ‘semi-structured interviews’, to seek views on a focused topic or, with key informants, for background information or an institutional perspective; ‘in-depth interviews’ to understand a condition, experience, or event from a personal perspective; and ‘analysis of texts and documents’, such as government reports, media articles, websites or diaries, to learn about distributed or private knowledge.

Qualitative research can be especially useful in both exploratory and explanatory contexts. For exploration, it allows you investigate situations where you would not know what hypotheses to examine or how to measure the concepts that interest you. For explanation, it allows you to examine "how and why" something is the way you observe it to be.
