What is what does empirical mean?

Empirical means based on observation or experience rather than theory or pure logic. It refers to information obtained through the use of one or more of the five senses (sight, hearing, touch, taste, smell), or through the use of instruments, machines, or other tools, to gather data that can be used to develop and test hypotheses or theories. Empirical research is often used in the sciences, social sciences, and other fields to study phenomena and make predictions about how they might behave in different situations. Empirical data is considered objective and reliable since it is derived directly from observations, measurements, and experiments, and can be verified or replicated by other researchers.
