Which of the following is a tentative idea or question that does not yet have evidence to support or refute it?
Terms in this set (10) What is the difference between a hypothesis and a prediction? A hypothesis is a tentative idea or question that is waiting for evidence to support or refute it, while a prediction is a guess at the outcome of a hypothesis.
What is the difference between a hypothesis and a prediction quizlet?
The difference between a hypothesis and a prediction is that a hypothesis is a proposed explanation for a set of observations; it leads to predictions that can be tested by additional observations or by experiments. A prediction is a guess of what might happen based on your observation/hypothesis.
Which of the following is characteristic of good theory or explanation?
One lesson is that the reason a “good” theory should be testable, be coherent, be economical, be generalizable, and explain known findings is that all of these characteristics serve the primary function of a theory–to be generative of new ideas and new discoveries.
What makes a theory strong?
A theory not only explains known facts; it also allows scientists to make predictions of what they should observe if a theory is true. The longer the central elements of a theory hold—the more observations it predicts, the more tests it passes, the more facts it explains—the stronger the theory.
What is the meaning of there is nothing so practical as a good theory?
The statement, “there is nothing so practical as a good theory” was of Kurt Lewin and it means that good theory is practical precisely because it advances knowledge in a scientific discipline, guides research toward crucial questions, and enlightens the professional management (Van de Ven, 1989).
Is a hypothesis A tentative explanation?
A hypothesis is a tentative explanation for an observation. A scientific theory is a well-tested and consistently verified explanation for a set of observations or phenomena.
What is Krashen’s hypothesis?
The Input hypothesis is Krashen’s attempt to explain how the learner acquires a second. language. In other words, this hypothesis is Krashen’s explanation of how second. language acquisition takes place.
What are the tentative explanation to the problem?
A hypothesis is a tentative explanation (i.e. an educated guess) for an observation, phenomenon, or scientific problem that can be tested by further investigation.
What are the two important qualities of hypothesis?
The two primary features of a scientific hypothesis are falsifiability and testability, which are reflected in an “If…then” statement summarizing the idea and in the ability to be supported or refuted through observation and experimentation.
Why is it important for a hypothesis to be falsifiable?
Falsifiability is the capacity for some proposition, statement, theory or hypothesis to be proven wrong. That capacity is an essential component of the scientific method and hypothesis testing. The requirement of falsifiability means that conclusions cannot be drawn from simple observation of a particular phenomenon.
