Non-observational

Describing a research methodology, study, or approach that does not directly involve the active monitoring, witnessing, or measurement of subjects or phenomena in their natural environment. It relies on data that has already been collected or generated, such as existing records, surveys, experiments conducted under controlled conditions, simulations, or theoretical models. It is often used when direct observation is impractical, unethical, or impossible, or when analyzing past events. The focus is on analyzing pre-existing data, or deducing information without directly watching the object of study.

Non-observational meaning with examples

This method helps them uncover broader trends and strengthen conclusions based on multiple independent data points.
