What is the definition of EMPIRICAL EVIDENCE?

• A testable idea or explanation that leads to scientific investigation.

• The observations, measurements, and other types of data that people gather and test to support and evaluate scientific explanations.

• A systemic study of natural events and conditions.

• A descriptive statement or equation that reliably predicts events under certain conditions.
