Definition

1. Adjective:
   • Relying on observation or experiment: Describes something that is derived from, supported by, or established through systematic data collection, such as observation, measurement, or experimentation, rather than theory or opinion alone.

Usage

The adjective "data-based" is used to qualify nouns, indicating that the thing described is grounded in empirical evidence. It is typically placed before the noun it modifies (attributive position).
