Testability, a property applying to an empirical The word empirical denotes information gained by means of observation, experience, or experiment. A central concept in science and the scientific method is that all evidence must be empirical, or empirically based, that is, dependent on evidence or consequences that are observable by the senses. It is usually differentiated from the philosophic hypothesis A hypothesis consists either of a suggested explanation for an observable phenomenon or of a reasoned proposal predicting a possible causal correlation among multiple phenomena. The term derives from the Greek, hypotithenai meaning "to put under" or "to suppose." The scientific method requires that one can test a scientific, involves two components: (1) the logical property that is variously described as contingency In philosophy and logic, contingency is the status of propositions that are not necessarily true or necessarily false. Here are four classes of propositions, some of which overlap:, defeasibility, or falsifiability Falsifiability is the logical possibility that an assertion can be shown false by an observation or a physical experiment. That something is "falsifiable" does not mean it is false; rather, that if it is false, then this can be shown by observation or experiment. Falsifiability is an important concept in science and the philosophy of, which means that counterexamples In logic, and especially in its applications to mathematics and philosophy, a counterexample is an exception to a proposed general rule. For example, consider the proposition "all students are lazy". Because this statement makes the claim that a certain property holds for all students, even a single example of a diligent student will to the hypothesis are logically possible, and (2) the practical Pragmatism is the philosophy of considering practical consequences and real effects to be vital components of meaning and truth. Pragmatism is generally considered to have originated in the late nineteenth century with Charles Sanders Peirce, who first stated the pragmatic maxim. It came to fruition in the early twentieth-century philosophies of feasibility of observing a reproducible Reproducibility is one of the main principles of the scientific method, and refers to the ability of a test or experiment to be accurately reproduced, or replicated, by someone else working independently series of such counterexamples if they do exist. In short, a hypothesis is testable if there is some real hope of deciding whether it is true or false of real experience. Upon this property of its constituent hypotheses rests the ability to decide whether a theory The term theory has two broad sets of meanings, one used in the empirical sciences and the other used in philosophy, mathematics, logic, and across other fields in the humanities. There is considerable difference and even dispute across academic disciplines as to the proper usages of the term. What follows is an attempt to describe how the term is can be confirmed or falsified by the data of actual experience. It means it can be tested, but it also can be proven wrong later.
In engineering this refers to the capability of an equipment or system to be tested
