Final answer:
Open-ended questions facilitate detailed and personal responses, providing qualitative data and insight into the interviewee's experiences, thoughts, and feelings.
Step-by-step explanation:
The type of questions that encourage the person being interviewed to speak out are open-ended questions. These questions are designed to elicit more detailed and personal responses, allowing for a wide range of answers that reflect the interviewee's thoughts, beliefs, and objectives. Unlike closed-ended, multiple-choice, or true/false questions that limit the answer to specific options, open-ended questions enable respondents to express themselves in a more expansive and descriptive way, providing qualitative data that can offer deeper insights into the subject being explored.
When designing an interview or questionnaire, open-ended questions are valuable tools for gathering qualitative information that is subjective and often based on what is seen in a natural setting. These questions do not aim for a simplistic 'yes' or 'no' or single-word response; instead, they prompt the interviewee to provide narrative-style answers that reveal more about their personal experiences and viewpoints.
Overall, open-ended questions serve not only to collect factual information but also give depth to an interview by allowing the capture of opinions, ideas, and feelings, which might otherwise be overlooked with more restrictive forms of questioning.
