Empirical research is based on observed and measured phenomena and derives knowledge from actual experience rather than from theory or belief.

Key characteristic that define an Empirical Study:

• Specific research questions to be answered

• Definition of the population, behavior, or phenomena being studied

• Description of the process used to study this population or phenomena, including selection criteria, controls, and testing instruments (such as surveys)

In addition to the aforementioned points, an Empirical Study usually follows a specific layout called the "IMRaD" format - Introduction, Methodology, Results and Discussion.
