What does The main purpose of science is to disprove your hypothesis mean?
Science and statistics are based on a confidence interval. The "Null Hypothesis" is the opposite of the hypothesis. It is often easier to consider disproving the null hypothesis than proving the hypothesis (to a certain confidence interval). Science experiments often have a very narrow scope. But, if one wishes to apply the conclusions to a wider scope, then one should look for new and unique ways to test or challenge the hypothesis. Perhaps that is where the "Global Warming" hypothesis has gone astray. Whether or not we are at a "local high" for the Holocene epoch, one doesn't have to look far into Earth's 4.5 billion year history to find both higher and lower temperatures on the planet. And, we have little direct data to show how a potential average temperature increase of a half a degree or so would affect the rain and water distribution around the planet. Again, historical and fossil records are often being ignored in favor of simplified computer algorithms.
Is it sufficient to do a single experiment to test a hypothesis Why or why not?
Whether or not you write down an hypothesis, if you conduct an experiment, you naturally have a hypothesis since you are trying to find the answer to something and have some sort of expectations.
Read the description of a science experiment below. Which part of the experiment is the second step of the scientific method (forming a hypothesis)?
she hopes to prove that heavier objects fall faster than lighter ones
What is the hyphotesis purpose?
An hypothesis, is of lower 'quality' than a thesis (aka a theory). 'Hypo' means before or earlier or above. An hypothesis is the gist of a query that may be untenable, or it may prove out a good field for study. I may hypothesize that it rains more frequently on a Monday. When I have collected the data, from reliable sources, I may then examine the validity of the hypothesis, and compare Monday rain frequency (or intensity) against 'other day' rain frequency. The hypothesis helps us formulate the method of the examination, the controls, and so on.
How do you write an interesting hypothesis?
A hypothesis is interesting when it is plausible. If you are well informed about the situation for which some hypothesis is needed, then you have a chance of coming up with a believable hypothesis. A very implausible hypothesis might be funny, but it would not really be an interesting hypothesis, insofar as it would be immediately dismissed other than as a subject of comedy.
What must happen for your hypothosis to be valid?
It depends upon the nature of your study. In systematic logic, there is no "truth" only valid, invalid, sound and unsound. Both are measures of the quality of a statement or argument (ala, your hypothesis) In scientific study, you would have to have a very narrow hypothesis that is testable to all applicable degrees. Once this hypothesis is tested against, you will know that it is true or false, if it is true, it becomes a theory (i might be skipping a few steps here for brevity's sake, but bear with me). In science, there are no facts, because your "theory" could be dis-proven in the future by the hypothesis of another. For instance, my hypothesis is that coins are affected by gravity to fall faster than feathers because they are heavier. I prove that they are heavier, and prove that unerringly, they fall faster than feathers. I cannot think of more tests, so I declare my hypothesis true. Another scientist hypothesizes that it has nothing to do with weight, and disproves my theory by finding a coin that is lighter than a feather, and showing that, in fact, it still drops at a faster rate than the feather. So his hypothesis is true. That causes me to think about my original hypothesis more, and then come up with the hypothesis of density being the causal factor. I prove yet again through testing. But my hypothesis is disproved by another scientist who puts both the feather and the coin in a vacuum, and showing that they drop at the same rate. To make my hypothesis completely moot, he finds a coin less dense than a feather, and shows that it still drops faster. Because of his experiment, he hypothesizes that it is friction that allows a feather to fall slowly, and proves it. That theory stands today. It is waiting for someone to disprove it and create a new hypothesis that outlasts it. however, you dont need a new hypothesis to disprove an old one, you just need a test that shows the old hypothesis to be untrue. For instance, using a vacuum doesnt necessarily prove anything until that scientist has his own hypothesis. what it does do, though, is disprove my older hypothesis that density is the causal factor.
What is the hypothesis for a magic balloon project?
The hypothesis of a magic balloon project, as with any project depends on what you are trying to prove from your experiment. If you were trying to prove that a certain kind of balloon stretches farther than another type, your hypothesis would state that.
How can you prove a conjecture false?
The word "conjecture" can be taken a number of ways. If the "conjecture" involves an inference based on false or defective information, you need only show convincing or conclusive evidence that the information is false or faulty. If the "conjecture" is the result of surmise or guessing, then it is nothing more than a guess itself, and, therefore, has no basis in fact or logic. If the "conjecture" is an unproven mathematical hypothesis, you will need to disprove its validity from its basis. Start with the basic crux of the problem and work step by step until you disprove (or prove) the hypothesis to be untrue (or true). Make sure you have good arguments and sound mathematics.
Is the Qur'an false?
Personally, I tend to believe all religious texts are false and deceiving. However, I cannot disprove them any more than their followers can prove them.
Why is a hypothesis important to a scientist?
Once a hypothesis have been confirmed through numerous experimental tests, it can then become a theory. Theories are much more powerful and expansive in scope than hypotheses. Once a theory has been established, it is the role of scientist to try and disprove a theory rather than to try to reinforce its proof.
Can the dead see from heaven good things on earth?
Personally, I believe it's a myth, but I can no more disprove the notion than the believers can prove it, so the answer, I suppose, would be maybe.
If a PhD candidate's research results in failure can he still get his PhD or must his research result in success?
The dissertation (research) must be defended successfully. The results of the research and experimentation do not have to be successful. The hypothesis must be determined and an experiment done to prove, or disprove, the hypothesis. If the results are inconclusive, the defense will involve showing what variables might have led to it being inconclusive. It must be definitive enough that a future researcher can build on the results, rather than having to start from scratch.
How do you use disprove and disapprove in a sentence?
I disapprove of your behaviour.(I do not approve)I can disprove that theory.(I can show that something is incorrect)
How do most often scientist gain new knowledge?
There are at least 2 ways: 1.Accidents. Often scientists will stumble upon new phenomena as they are attempting to prove or disprove something else. The new and unexplained phenomena ends up being more scientifically relevant than what they are initially trying to prove. An example of this would be Marie Curie accidentally discovering radium, or Percy LeBaron accidentally discovering that microwaves can be used to heat materials. 2.The Scientific Method (hypothesis testing). In hypothesis testing, a scientist will establish a hypothesis, then test his theory to determine if the hypothesis is true or false. He often uses a control group to compare his experiment to, to determine if the results of the experiment were substantial enough to prove the hypothesis. Hypothesis testing relies on accurate and detailed observation, measuring, and recording of data. New information comes about when a scientist has proven or disproven a hypothesis. An example of a famous hypothesis test would be Galileo's experiments with gravity on the leaning tower of Pisa. Galileo hypothesized that a heavier object would fall faster than a lighter object. He conducted an experiment in which he dropped two objects of different weights simultaneously to see which hit the ground first. He recorded the data, and repeated the experiment several times until he was sure of the results. The new knowledge that he gained was that any two objects would hit the ground simultaneously, regardless of weight.

How long will it be before you can send telescopes in space far enough to look backwards in time on the earth to disprove or prove creation or evolution?
We would need to be able to travle faster than the speed of light so..... No
What is a good hypothesis for does color affect memory?
I might hypothesize that very colorful objects are easier to remember than blandly colored or black and white objects. Possibly a flash card type test could be used to investigate the hypothesis.
