Which term refers to a systematic investigation to establish facts or principles?

• A. Research methodology
• B. Questionnaire
• C. A (research) study
• D. Dataset

Answer: (C)

A systematic investigation designed to establish facts or principles is called a research study. It refers to the structured process of asking a question, choosing a design, collecting and analyzing data, and drawing conclusions that establish facts or principles. The other terms point to parts or outputs of research rather than the entire inquiry: methodology is the plan or approach used, a questionnaire is just one data-collection tool, and a dataset is the collected data itself. So the term that best names the complete, methodical inquiry is a research study.
