What else can I help you with?
Why is hypothesis could be rejected?
To reject null hypothesis, because there is a very low probability (below the significance level) that the observed values would have been observed if the hypothesis were true.
What is hypothesis that is not supported by the data that has been collected and analyzed?
It is inaccurate.
What hypothesis have the Grants been testing?
The Grants have been able to provide clear evidence for natural selection and supported Darwin's theory. The hypothesis was that natural selection can occur many times in a lifetime.
If the null hypothesis is true and the researchers do not reject it then a correct decision has been made?
True because the point of the hypothesis test is to figure out the probability of the null hypothesis being true or false. If it is tested and it is true, then you do not reject but you reject it, when it is false.
When analyzing what has been observed such as data collected in an experiment leads to?
hypothesis .
A hypothesis that has been verified by many scientists?
scientific theory
What is a hypothesis that has been repeatedly and rigorously tested and supported?
The hypothesis which has been tested and verified repeatedly by tests is called theory.
When a rule is proposed to describe the behavior of something in nature it is called what?
A rule that is proposed is called a hypothesis. Once it has been tested and verified it becomes a theory.
What is A broad idea that has been repeatedly verified so as to give scientists great confidence that it represents reality is called?
theory
When a scientific idea is proposed is it a hypothesis or theory?
It begins as a hypothesis, only after it has been thoroughly tested over time can it be called a theory. (Note that what non-scientists call a theory is actually just a hypothesis.)
What is a principle that has been scientifically verified?
One principle that has long been scientifically verified is that of gravity. Scientists agree that the law of gravity operates on earth.
How does a scientific from a hypothesis?
once a hypothesis has been supported in repeated experiments, scientists can begin to develop a theory.
What is a verified answer?
A verified answer is one that has been checked several times to confirm that the answer is correct and factual. If it has not been checked or is incorrect then it cannot be called a verified answer.
How does a scientific theory from a hypothesis?
once a hypothesis has been supported in repeated experiments, scientists can begin to develop a theory.
Differentiate theory from law?
In science the things called "laws" are invariably just rules-of-thumb that hold true only under ideal conditions. For instance : the gas laws - they only hold for low pressure and high temps ... and if you don;t believe that, then what are vapor tables for? A "theory" is any hypothesis that's been verified so often that "everybody" believes it. Note that non-scientists can not distinguish between theory, hypothesis, and crack-pot notion.
Why is a hypothesis that is unsupported by observation rejected by scientists?
Simply put, because there is not enough evidence to support it. "Rejected by scientists" should not be taken to always mean "scientist believe it is impossible" - rather, consistent evidence that support the hypothesis has not been produced.
Can a hypothesis that has been rejected be of any value to scientists?
Yes. But usually a hypothesis (if, then, because statement) is changed overtime to establish a conclusion on the investigation. The point of the collection of the data is to show whether or not the hypothesis was supported, and if not needs to be corrected/modified. Certain parts may still be helpful/kept but in most cases it is changed
