... ( hypothesis testing ) A hypothesis is an untested statement about the relationship (usually of association or causation) between concepts within a given theory . Hypothesis testing involves the testing of a hypothesis in a scientific manner, and hence requires a precise statement of the supposed relationship between the concepts under investigation, and the data which would need to be collected for the testing to take place. Hypothesis testing is perhaps best seen as involving falsificationism . See also deduction...

... An idea or concept that provides a basis for arguments or explanations which can be tested by experimentation. In inductive or inferential statistics, the hypothesis is usually stated as the converse of the expected results, i.e. as a null hypothesis ( H 0 ). This helps workers to avoid reaching a wrong conclusion, since the original hypothesis H 1 will be accepted only if the experimental data depart significantly from the values predicted by the null hypothesis. Working in this negative way carries the risk of rejecting a valid research hypothesis...

It may be a theory or law that has the status of not being incontrovertible or universally true.

... A provisional explanation of a phenomenon, formally framed as a proposition . It may be debated by rational argument and/or tested empirically. Hypothesis testing requires a precise and testable statement of such a claim or prediction, and the collection of appropriate data against which it can be tested. More loosely, Gregory sees perception as a process of hypothesis-testing. ...

In inductive or inferential statistics the hypothesis is usually stated as the converse of the expected results, i.e. as a null hypothesis ( H 0 ). For example, if a specified feature were being compared in 2 samples, the null hypothesis would be that no difference existed in the populations from which the samples were taken. This helps workers to avoid reaching a wrong conclusion, since the original hypothesis H 1 will be accepted only if the experimental data depart significantly from the...

... . A hypothesis is a guess, hunch, or supposition taken as a basis for reasoning. The method of hypothesis, one of the major scientific methods, has had a career coincident with, and tangled up in, that of modern science. Rene Descartes brought the method of hypothesis to the fore in his Principles of Philosophy ( 1644 ). He argued that the world presents itself as the face of a clock whose internal workings are hidden. To talk about the workings, we must resort to hypothesis or conjecture. Similarly, while we can observe the reflection and...

... . A hunch, speculation, or conjecture proposed as a possible solution to a problem, and requiring further investigation of its acceptability by argument or observation and experiment . Hypotheses are indispensable to human thinking, and used by everyone from detectives (Sherlock Holmes) to metaphysicians. They formthe basis of an influential account of scientific method ( hypothetico-deductive method ), which is closely related to the claim, associated with Popper , that scientific theories are empirical hypotheses and remain so, however successful...

... A statement about the behaviour of social or biophysical phenomena whose validity can be tested by systematic observation of these phenomena. The term is widely used in the life, earth, and computational sciences, less so in the contemporary social sciences. To qualify as a hypothesis a statement’s validity must be uncertain and able to be tested empirically, although theoretical and mathematic tests may suffice as heuristics en route to real world testing. A hypothesis is thus a conjecture made by scientific researchers on the basis of one or more...
