What form of research describes observation of natural phenomena without interference, focusing on relationships instead of causality?

• A. Correlational research
• B. Experimental research
• C. Case study
• D. Longitudinal study

Answer: (A)

Correlational research aims to describe how variables relate to one another as they occur in the real world. It involves observing phenomena in natural settings without attempting to influence or control them, and it focuses on whether and how variables covary. Because there’s no manipulation, you can identify relationships and estimate their strength and direction, but you can’t determine causation—there may be other variables at play or reverse directions of influence. This matches the idea of observing natural phenomena and looking at relationships rather than proving that one thing causes another. In contrast, experimental research involves changing something to test causality, a case study is an in-depth look at a single case, and a longitudinal study tracks the same subjects over time to observe changes, which are not the best fit for describing natural relationships without interference.
