A thing is evidence for a proposition if it epistemically supports this proposition or indicates that the supported proposition is true. Evidence is empirical if it is constituted by or accessible to sensory experience. There are various competing theories about the exact definition of the terms evidence and empirical. Different fields, like ...
Such evidence is expected to be empirical evidence and interpretable in accordance with the scientific method. Standards for scientific evidence vary according to the field of inquiry, but the strength of scientific evidence is generally based on the results of statistical analysis and the strength of scientific controls.

Empirical research is research using empirical evidence. It is also a way of gaining knowledge by means of direct and indirect observation or experience. Empiricism values some research more than other kinds. Empirical evidence (the record of one's direct observations or experiences) can be analyzed quantitatively or qualitatively.
Empiricism, often used by natural scientists, believes that "knowledge is based on experience" and that "knowledge is tentative and probabilistic, subject to continued revision and falsification". [6] Empirical research, including experiments and validated measurement tools, guides the scientific method.
According to the positive-instance approach, an observation sentence is evidence for a universal hypothesis if the sentence describes a positive instance of this hypothesis. [ 41 ] [ 48 ] [ 49 ] For example, the observation that "this swan is white" is an instance of the universal hypothesis that "all swans are white".
These projects are a type of case study and use multiple methods of evidence collection. [34] The working hypotheses are used as a device to direct evidence collection. As a result, working hypotheses are generally organized using sub-hypotheses, which specify in more detail the kinds of data or evidence needed to support the hypothesis. [3]
These same workers also tend to be opposed to overhauling the system. As the study pointed out, they remain loyal to “intervention techniques that employ confrontation and coercion — techniques that contradict evidence-based practice.” Those with “a strong 12-step orientation” tended to hold research-supported approaches in low regard.
In the legal sphere, anecdotal evidence, if it passes certain legal requirements and is admitted as testimony, is a common form of evidence used in a court of law. Often this form of anecdotal evidence is the only evidence presented at trial. [30] Scientific evidence in a court of law is called physical evidence, but this is much rarer ...
