What is the investigation study of sources to establish facts known as?

The term that refers to the investigation study of sources to establish facts is research. Research involves a systematic process of inquiry where information is gathered, evaluated, and analyzed to answer questions or solve problems. It typically encompasses various methodologies to explore topics deeply and ensure the reliability of findings through thorough examination.

In contrast, analysis refers to the examination and interpretation of the data collected during the research; it is a component of the research process rather than the entirety of it. Inspection typically involves a closer examination or physical check of a subject or object, which may be a part of the research process but does not encompass the broader investigative nature that research implies. A survey is a specific method of data collection, often used in research to gather information from a population, but it is not synonymous with the overall process of investigating and establishing facts.
