Empirical Evidence: Empirical evidence refers to the data or observations collected from experiments or studies that support or refute a hypothesis. It is based on actual experience or observation rather than theory.
Scientific Research: Scientific research involves systematic investigation conducted using rigorous methods to gather empirical evidence and test hypotheses in order to expand our knowledge about various phenomena.
Theory: A theory is an explanation or model that attempts to describe and predict how certain phenomena occur. Theories are based on existing evidence but may evolve as new evidence emerges.
