What method consists of a collective interview guided by a moderator to generate rich data from participants?

The method that consists of a collective interview guided by a moderator to generate rich data from participants is indeed the focus group. In a focus group, a small group of participants engages in an open discussion about a specific topic, facilitated by a moderator who encourages dialogue and helps steer the conversation to ensure diverse perspectives are heard. This format allows for dynamic interaction among participants, fostering a depth of understanding and insight into their thoughts, feelings, and experiences related to the topic at hand.

Focus groups are particularly valuable in research as they can uncover themes, ideas, and social dynamics that might not emerge in individual interviews. This method leverages the group setting to stimulate discussion and reveal rich qualitative data, making it useful in various fields, including psychology, marketing, and social research, where understanding people's perceptions and motivations is key.

The other methods listed do not fit this description. Conversation analysis is primarily concerned with the structure and organization of spoken interaction; narrative analysis focuses on the stories people tell and how they shape meaning; and field notes involve observational documentation rather than guided interviews. Each of these methods serves different research purposes and yields different types of data, but for the purpose of collective, moderated interviews that produce rich, interactive discussions, the focus group is the most appropriate choice.
