Open-ended (indeterminate) refers to situations or questions that do not have a fixed or definitive answer. These types of inquiries allow for a range of responses, encouraging creativity and exploration. For example, asking someone, "What do you think about art?" invites personal interpretation rather than a single correct answer. In research or assessments, open-ended questions can provide deeper insights into opinions and experiences. Unlike closed questions, which limit responses to "yes" or "no," open-ended questions promote discussion and can reveal complex thoughts. This approach is often used in fields like psychology and education to gather qualitative data.
