What term describes knowledge that is derived from observations and experiences?

The term that describes knowledge derived from observations and experiences is empirical knowledge. This type of knowledge is based on evidence that is obtained through direct experience, experimentation, or observation rather than through theory or speculation. Empirical knowledge is often contrasted with theoretical knowledge, which is derived from logical reasoning and the formulation of models or principles that explain phenomena.

Empirical knowledge is essential in fields such as the sciences and nutrition, where practical data and real-world experiences help to form a comprehensive understanding of concepts and principles. By relying on observations, individuals can draw conclusions that are grounded in reality, leading to a more informed approach to practical applications.

The other terms, though related to the acquisition of knowledge, do not specifically refer to this experiential and observational basis. Theoretical knowledge emphasizes abstract concepts and ideas, speculative knowledge involves conjectures and hypotheses without conclusive evidence, and notional knowledge pertains to notions or beliefs that may not be substantiated by direct experience.
