Which scientific approach focuses on collecting data through observation and description rather than testing a hypothesis?

Observational/descriptive science emphasizes collecting data through careful observation and description rather than testing a specific prediction. In this approach, scientists document phenomena as they occur, measuring and recording what's observable, often without manipulating variables. This yields rich, descriptive data and helps reveal patterns or relationships that can inspire formal hypotheses later. A classic example is natural-history fieldwork that catalogs species, tracks distributions, and notes behaviors and environmental context simply through observation and description. By contrast, hypothesis-driven science starts with a testable prediction and uses experiments or controlled observations to determine whether the results support or refute that prediction, typically manipulating variables to isolate cause and effect. The broader scientific method encompasses both approaches, while a theory represents a well-supported explanation, not a data-collection approach.
