In this method, the researcher gets direct information from the respondent through dialogues and conversations.
Detailed Explanation
The interview method enables researchers to gather qualitative data directly from individuals. It involves a face-to-face conversation where the interviewer asks questions, and the respondent provides answers. This method allows for a deeper understanding of the subject since the interviewer can ask follow-up questions and clarify doubts immediately. The conversational nature helps in creating a comfortable environment, which may lead to more honest and detailed responses.
Examples & Analogies
Imagine you're a detective trying to solve a mystery. You would want to talk to witnesses directly, asking them questions about what they saw. This method allows you to gather specific details and emotions behind their experiences, which helps you piece together the complete picture.

However, the interviewer must take the following precautions while conducting an interview with people of the area:
(i) A precise list of items about which information is to be gathered from the persons interviewed be prepared.
(ii) The person(s) involved in conducting the interview should be clear about the objective of the survey.
(iii) The respondents should be taken into confidence before asking any sensitive question and he/she be assured that the secrecy will be maintained.
(iv) A congenial atmosphere should be created so that the respondent may explain the facts without any hesitation.
(v) The language of the questions should be simple and polite so that the respondents feel motivated and readily agree to give the information asked for.
(vi) Avoid asking any such question that may hurt the self-respect or the religious feelings of the respondent.
(vii) At the end of the interview, ask the respondent what additional information he/she may provide, other than what has already been provided by him/her.
(viii) Pay your thanks and gratefulness for sparing his/her valuable time for you.
Detailed Explanation
Conducting an interview requires careful planning and sensitivity. First, the interviewer must prepare a list of topics or questions to ensure all necessary information is gathered. It's essential to clarify the survey's purpose to the interviewee to build trust. Creating a comfortable environment is critical to make respondents feel at ease, allowing them to share freely. The language used should be respectful and straightforward, avoiding any questions that could offend or hurt feelings. After the interview, it is good practice to thank the respondent, showing appreciation for their time and insights.
Examples & Analogies
Think of interviewing like hosting a dinner party. You want to prepare a meal (your questions) that your guests (respondents) will enjoy. You also need to create a warm atmosphere so they feel comfortable sharing their thoughts while being careful not to touch on topics that could make them uncomfortable. Just as youโd thank your guests for coming, you should thank your respondents for their time, ensuring they leave with a positive impression.

The language of the questions should be simple and polite so that the respondents feel motivated and readily agree to give the information asked for.
Detailed Explanation
In interviews, the way questions are crafted significantly impacts the quality of responses. Questions should be formulated in simple language that respondents can easily understand. Using polite and courteous language encourages cooperation from the respondents and often yields more detailed and thoughtful answers. It's important to consider the cultural and social context of the respondents, as different groups may respond differently to various types of questioning.
Examples & Analogies
Imagine you're a teacher asking your students about their favorite subject. If you ask, 'What is your most preferred academic field and why does it resonate with your inclinations?' some may feel overwhelmed or confused. But if you say, 'What is your favorite subject in school, and why do you like it?' it's more approachable, and kids are likely to share their thoughts openly.
