What research technique involves structured conversations to explore a topic in-depth?

The research technique that involves structured conversations to explore a topic in-depth is in-depth interviews. This method allows for a one-on-one discussion between the researcher and the participant, providing the opportunity to delve deeply into the participant's perspectives, feelings, and insights regarding a specific topic.

In-depth interviews are characterized by their flexibility, allowing the interviewer to probe deeper based on the participant's responses. This approach can uncover nuanced opinions and detailed information that may not be accessible through more quantitative methods.

While focus groups also explore topics in-depth, they do so in a group setting, which can lead to a dynamic exchange of ideas but may not allow for the same level of individual exploration as in-depth interviews. Surveys and online polls typically rely on structured questions and are more suited for gathering quantitative data from a larger audience, rather than focusing deeply on individual perspectives.
