Final answer:
The advantages of conducting interviews include obtaining answers for unasked questions, learning from nonverbal responses, presenting questions objectively, discovering new entities, and gathering rich and complex information.
Step-by-step explanation:
An interview is a one-on-one conversation between the researcher and the subject, and it is a way of conducting surveys on a topic. However, participants are free to respond as they wish, without being limited by predetermined choices. In the back-and-forth conversation of an interview, a researcher can ask for clarification, spend more time on a subtopic, or ask additional questions. In an interview, a subject will ideally feel free to open up and answer questions that are often complex. There are no right or wrong answers. The subject might not even know how to answer the questions honestly.
Interviews can also provide a more dynamic source of information about the participant than standard testing measures. Nonverbal responses, such as body language, can reveal important insights. Additionally, questions in an interview are presented more objectively compared to closed-ended questions used in survey techniques, allowing for a more in-depth understanding of the participant's perspective.
In conclusion, the advantages of conducting interviews include: 1) the ability to obtain answers for unasked questions, 2) the opportunity to learn from nonverbal responses, 3) the presentation of questions in a more objective manner compared to surveys, 4) the potential to discover new entities, and 5) the ability to gather rich and complex information.
