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 describes a study aimed at evaluating something in detail through a set of questions directed at a specific group of people is "Survey."

Surveys are structured tools used in research to collect data from respondents. They are designed to gather information about opinions, experiences, or behaviors from a defined audience, which makes them essential for understanding trends and gathering insights on various topics. The data collected can be quantitative or qualitative and helps in making informed decisions or assessments based on the responses received.

The other terms, while related to various aspects of study and analysis, do not accurately describe the process of gathering detailed evaluations through questioning. Goals refer to objectives that an individual or organization aims to achieve. Estimates typically involve approximations or educated guesses regarding quantities or values. A budget is a financial plan that outlines expected income and expenditure over a specified period. None of these terms specifically refer to the methodical collection of insights through questions, which is precisely what a survey entails.
