Yes, a hypothesis is a proposed explanation that has not been extensively tested or confirmed, while a theory is a well-supported explanation that has been validated through repeated testing and observation. In scientific terms, a theory is considered more established and supported than a hypothesis.

How does a scientific theory compare a scientific hypothesis?
Scientific theories base on facts depending on the observation made while hypothesis is a tentative answer or solution to a given problem. In other words, theory is all about possible facts but they may not always be true and hypothesis, is an intelligent answer to a particular scientific problem.
Is the theory true that the theory of evolution is supported by a wide range of biological evidence?
Yes. If evolution was not widely supported by evidence, then it would be regarded as a hypothesis rather than a theory.
Why do scientists call evolution a theory?
Because it cannot be proven or replicated.AnswerIn science, a hypothesis is a good idea, a possible explanation, which might be right and might be wrong. Hypotheses can be refuted by experimentation. If the expectation from the hypothesis is not met by the outcome of experiment, the hypothesis is refuted. The longer a hypothesis survives unrefuted the more confidence we have in it. Evidence can support a hypothesis. The more evidence one has in support of a hypothesis, the more grows our confidence in it. Within the philosophy of science of Karl Popper, a hypothesis cannot be proven, but one can have a mighty amount of confidence in one, proportional to the amount of evidence in support of it. Unrefuted and with backing evidence, a hypothesis is promoted to a theory! A theory is better than a hypothesis. Evolution has much evidence from comparative genetics, comparative morphology and the fossil record. Evolution was once a hypothesis. Darwin collected a large mass of evidence for On the Origin of Species and now we have evidence from Mendelian genetics and comparative genetics, which Darwin knew nothing of. We now have a greater fossil record than Darwin did. There is far more evidence these days (for what is now called Neodarwinism or the Modern Synthesis- the combination of genetics and Darwin's basic 1859 ideas) than there was in Darwin's time. Evolution now has so much evidence that it is best to call it a theory, rather than a hypothesis. Yes, theories are unproven, but in Popperian philosophy of science they cannot be proven. Theories survive refutation and have much evidence and explain a lot. Biology regards evolution as its baseline, its most important idea ever. It might only be a theory of which we can only be 99% confident, but it explains everything so well that most biologists should better call it a fact rather than a theory. Evolution is such a good theory that its pedantic differentiation from 'fact' is entirely unnecessary.
How is H1 hypothesis rejected?
H1 hypothesis is rejected when the p-value associated with the test statistic is less than the significance level (usually 0.05) chosen for the hypothesis test. This indicates that the data provides enough evidence to reject the alternative hypothesis in favor of the null hypothesis.
A scientist on television states that a hypothesis cannot be proven Access why this statement is correct?
This statement is correct because a hypothesis is a proposed explanation that has not been validated through experimentation and evidence. Scientific inquiry aims to test and gather evidence to support or reject a hypothesis, rather than proving it true. It is always possible for new evidence or data to emerge that could challenge or refine a hypothesis.
Is it true that the theory of evolution is supported by a wide range of biological evidence?
Yes. If evolution was not widely supported by evidence, then it would be regarded as a hypothesis rather than a theory.
Does a theory take longer to develop than a hypothesis Why?
Yes, a theory takes longer to develop than a hypothesis because a theory is a well-supported explanation that has been extensively tested and validated, whereas a hypothesis is an initial idea or prediction that has yet to be tested. The process of developing a theory involves conducting numerous experiments, observations, and analyses to accumulate evidence and support the proposed explanation.
Is a hypothesis is more certain than a theory in science?
No. A theory is more certain: it is a hypothesis which has had some supporting evidence.
How are hypothesis theory and law related?
In science, a hypothesis is a proposed explanation for a phenomenon based on observations and background knowledge. If a hypothesis is tested repeatedly and consistently supported by evidence, it may be elevated to the status of a theory. A scientific law, on the other hand, is a concise statement that describes a fundamental relationship between variables in nature, often derived from repeated observations and experimental data. Laws are typically more general and less explanatory than theories.
How do the terms 'hypothesis' and 'theory' differ from the public and from a biologist's approach?
A hypothesis is a good acurate guess based on the facts and evidence, while a theory is just a wild guess. But a hypothesis and theory's are both made by scientists with more knowledge than a regular, ordinary person.
What primary difference between a scientific theory and a hypothesis is that a theory is?
A scientific theory is more elaborated than a simple hypothesis and generally is validated by experiments.
Why is the solar nebula theory a theory rather than a hypothesis?
The solar nebula theory is considered a theory rather than a hypothesis because it is a well-substantiated explanation supported by a substantial body of evidence from various fields, including astronomy, geology, and physics. It provides a comprehensive framework for understanding the formation and evolution of the solar system, incorporating observations of protoplanetary disks and the distribution of elements in the solar system. Unlike a hypothesis, which is a testable prediction or assumption, a theory is a robust explanation that has withstood extensive testing and scrutiny over time.
How does a scientific theory compare a scientific hypothesis?
Scientific theories base on facts depending on the observation made while hypothesis is a tentative answer or solution to a given problem. In other words, theory is all about possible facts but they may not always be true and hypothesis, is an intelligent answer to a particular scientific problem.
Is the theory true that the theory of evolution is supported by a wide range of biological evidence?
Yes. If evolution was not widely supported by evidence, then it would be regarded as a hypothesis rather than a theory.
How does the strength of a scientific theory compare to the strength of a hypothesis?
A scientific theory is a well-substantiated explanation of some aspect of the natural world that is supported by a large body of evidence. It is stronger than a hypothesis, which is a proposed explanation for a phenomenon that can be tested through experimentation and observation but has not yet been extensively validated. The strength of a theory lies in its predictive power and ability to explain diverse observations.
What is the relation between a hypothesis and theory?
A hypothesis is a tentative theory which is unverified, but if true could explain selected facts or observations. A hypothesis expresses an opinion which isn't necessarily based on provable evidence. A theory is a little more solid than a hypothesis, so a hypothesis when tested and proved to have some basis might become a theory. A theory might also refer to a belief with little or no fact behind it at all: he has a theory that the month in which people are born affects their personalities.
Why is a theory more accepted than hypothesis?
A theory is more accepted than a hypothesis because it is a well-substantiated explanation of a phenomenon based on scientific evidence, testing, and broader consensus among experts. Theories undergo rigorous testing and scrutiny, whereas a hypothesis is a proposed explanation that has yet to be fully tested or proven.
