[See null hypothesis

a question about the natural world that can be verified or disproved by observation and/or experimentation.

That is, any hunch about the types of people, relationships among the different actors and actresses, or the way things are done in the target community. Such hypotheses then serve as guidelines for the design of information-gathering. Hypotheses may be deduced from theoretical systems, or they may arise inductively from specific empirical observations. They may also arise, seemingly spontaneously, from your thought processes.

hypothesis is a scientist's best estimation, based on scientific knowledge and assumptions, of the results of an experiment. It usually describes the anticipated relationship among variables in an experiment. The anticipated relationship between the dependent and independent variables is the result you expect when one variable reacts with another. A hypothesis typically leads to the crucial questions that must be addressed in the lab: did you find what you expected to find? Why or why not? The point of an experiment is to test the hypothesis.

A hypothesis is a tentative explanation of existing data that is based on previous knowledge and that guides further inquiry through observing or experimenting. Hypotheses are derived from inferences drawn from observations and based on theory. They are offered as possible explanations and are generally stated in such a way that they lead to testable predictions.

A hypothesis is a tentative supposition with regard to an unknown state of affairs, the truth of which is thereupon subject to investigation by any available method, either by logical deduction of consequences which may be checked against what is known, or by direct experimental investigation or discovery of facts not hitherto known and suggested by the hypothesis (McGraw-Hill, Concise Encyclopedia of Science and Technology).

A tentative assumption made in order to draw out and test its logical or empirical consequences.

a tentative explanation for a question that can be tested by experimentation

a hypothesis is a provisional theory about some aspect of the world, or more narrowly the relationship between variables, which can be subject to test. In formulating a hypothesis it is important to specify limits the limits of its applicability. It is often possible to reformulate a research question as a hypothesis to be tested.

This is the supposition made as the basis for testing, used as the starting point for further investigation into finding defects. Normally a hypothesis for developing tests would include assumptions such as the following: "the documentation from which the tests are to be developed is almost entirely correct."

An answer to a question about a problem that can be true or false, and may or may not be supported by evidence 20, 50

A precise statement that makes a prediction about the results of a study. The purpose of the study is to test this prediction. A hypothesis is an element of a theory. A theory should consist of at least one testable prediciton. An experiment usually consists of an experimental hypothesis and a null-hypothesis.

(hð poth‚ƒ sis, hi-) n., pl. -ses (-sŽz) a provisional theory or assumption set forth to explain some class of phenomena. return

An educated guess. A speculative model for explaining something, which is based on what has been established to date. This is the first stage in scientific work. Hypotheses must then be scrutinized and tested against evidence in order to be considered "verified" to any degree. Non scientists commonly use the word "theory" for what is actually a mere hypothesis. This leads to a great deal of misunderstand and an under-appreciated level of certainty when the public hear scientists use the word "theory". For the actual definition of "theory", see that entry.

A hypothesis (from Greek ) consists either of a suggested explanation for a phenomenon or of a reasoned proposal suggesting a possible correlation between multiple phenomena. The term derives from the ancient Greek, hypotithenai meaning "to put under" or "to suppose". The scientific method requires that one can test a scientific hypothesis.
