What term describes a study to evaluate something in detail using a set of questions aimed at a specific group of people?

The term that best describes a study designed to evaluate something in detail using a set of questions aimed at a specific group of people is "survey." A survey is a systematic method for collecting data and opinions from a targeted segment of the population. It often involves a structured set of questions that can be administered through various formats, such as online, via phone, or in person, allowing researchers to gather quantitative and qualitative information effectively.

While a poll typically focuses on gauging public opinion on a specific issue or question and is often less detailed than a survey, an interview denotes a more personalized, in-depth conversation usually conducted one-on-one, which does not necessarily follow a standardized question format. Analysis refers to the examination of data or information, but it does not inherently involve the process of collecting that data through questions. Thus, "survey" is the most accurate term for this context, as it encapsulates the essence of systematically obtaining insights through a predefined set of questions.
