Which method is used to gather information through structured questioning?

1. Observation

2. Questionnaires

3. Field surveys

4. Client interviews

The correct answer is: Questionnaires

Using questionnaires to gather information through structured questioning is a highly effective method within design and research contexts. Questionnaires are designed with specific questions that are standardized, allowing for consistent data collection from multiple respondents. This method ensures that each participant has the same opportunity to provide their feedback, which can subsequently be quantified and analyzed. The structured nature of questionnaires—often consisting of closed-ended questions, scales for rating, or yes/no queries—facilitates easy comparison and statistical analysis of the gathered data. This is particularly valuable when seeking specific information or quantitative data related to design preferences, needs, or demographics. In contrast, other methods, such as observation, field surveys, and client interviews, may not adhere to a standardized questioning format. Observation involves noting behaviors or nuances without predetermined questions, while field surveys might have a broader scope and less structure. Client interviews, though informative, rely on open conversations that may not yield data that is as easily quantifiable. Therefore, the structured approach of questionnaires makes them a preferred choice for gathering targeted information effectively.
