Which term is used for research that uses observed data rather than theoretical work?

• A. Empirical Research
• B. Research Question
• C. Hypothesis
• D. Gold Standard

Answer: (A)

Empirical research relies on observed data and experience rather than theory alone. It involves collecting measurements, observations, experiments, or surveys and then analyzing the data to draw conclusions. This makes it the best fit for the description because it directly uses what can be seen or measured in the real world.

The other terms refer to different ideas: a research question is what you aim to investigate; a hypothesis is a testable guess about the relationship between variables; and the gold standard is the most trusted method or benchmark used for comparison. So, the described term is empirical research.
