Empirical evidence is information that verifies the truth or falsity of a claim. In the empiricist view, one can claim to have knowledge only when based on empirical evidence. Empirical evidence is evidence that can be observed through the senses: it can be seen, touched, heard, smelled, tasted and, to some extent, measured. Empirical evidence, distinct from empirical research, refers to objective evidence that appears the same regardless of the observer. Empirical research yields empirical evidence. Empirical evidence is the only form of evidence acceptable to positivism which describes social science as the study of a social world deemed to be external to the observer and proceeding with the researcher being a neutral observer of that external world.
Empirical evidence is required for a hypothesis to gain acceptance in the scientific community. Empirical evidence is scientifically-based research from fields such as psychology, sociology, economics, and neuroscience, and especially from research in educational settings. Empirical evidence data on performance is used to compare, evaluate, and monitor progress. Empirical evidence method is generally meant as the collection of data on which to base a theory or derive a conclusion in science. It is part of the scientific method, but is often mistakenly assumed to be synonymous with the experimental method. The term Empirical Evidence comes from the Greek word for experience.
The philosophical belief that sensory input 'Empirical evidence' (seeing, touching, and hearing) is the sole source and test of knowledge.
Empiricism is a theory of knowledge which emphasizes those aspects of scientific knowledge that are closely related to experience, especially as formed through deliberate experimental arrangements.
It is a fundamental requirement of scientific method that all hypotheses and theories empirical evidence tested against observations of the natural world, rather than resting solely on a priori reasoning, intuition, or revelation. Hence, science is considered to be methodologically empirical in nature.
