Step-by-step explanation:
In formative research, intercept interviews refer to a common qualitative method used to develop hypotheses, explore broad topics, and generate ideas. Intercept interviews consist of a small group of 8 to 10 people who are interviewed to gather their perspectives and insights. These questions allow participants to share their thoughts extensively, providing qualitative data that are rich in detail and insight. The nature of these interviews is more spontaneous, similar to unstructured interviews, which aim to have interviewees relate information in an open and neutral environment, offering subjective and varied responses.
