Not always. This is kind of hard to explain but sometimes, one of your variables will make the whole expirement kinda slide and the data might be wrong. Just asking, is this a science fair project :D
Because it has been proven by many experiments by many scientists
Bias in the data is inaccurate data. Any error in data will yield false results for the experiment. Experiments by their nature must be exact. Many trials are not accepted until the results can be duplicated.
Believe is a verb, it indicates that a person has come to some kind of conclusion or has accepted something as being factual or true, as in, I believe that you are a good person. Belief is a noun, it is a specific assertion, conclusion, or datum of whatever sort, that someone has accepted as true. It is my belief that you are a good person. Belief in evil spirits is superstitious. Hence, I do not believe in evil spirits.
A scientific theory is a deductive statement accepted by a recognized element of the scientific community, and that represents the only possible conclusion of a thorough, rigorous, and disciplined series of scientific testings of successive critically reasoned hypotheses. A scientific theory is often a set of statements that collectively describe how one facet of the universe works. Unlike common theories, scientific theories must be:consistent with all existing scientific laws and constants;consistent with, and supported by, all reproducible scientific observations and experimental results; andself consistent - that is, it does not contradict itself in any way.#1 is questionable. Darwin's theory of evolution by natural selection directly contradicted and invalidated Lamarck's theory of evolution by the inheritability of acquired traits.A scientific theory must be:1. Naturalistic. It cannot invoke the intervention of a deity, or of a "superior" being or beings, or of unknown physical laws not in operation today (a common creationist claim). It also must be supported by observable facts and reproducible experiments. "Cold fusion theory" is naturalistic, as it does not invoke divine or supernatural intervention, but it is not supported by reproducible experiments. It is therefore not scientific.2. Falsifiable. It must be open to being disproven when a newer theory, accounting better for all the facts, is formulated. To claim that present life-forms were created by an all-powerful, essentially unknowable Divine Creator, is an unfalsifiable claim, and therefore scientifically invalid.3. Predictive. A scientific theory should be able to predict what will happen under specific conditions. Because creationism cannot predict anything (since everything depends on the will of the Creator), it is not scientific. In the field of evolution, predictability works this way: given certain environmental conditions, scientists can predict that the life-forms developing under those conditions will show adaptations to take the greatest advantage of such conditions. For example, it can be safely predicted that, in the Sahara desert, life-forms, whether animal or plant, will have metabolisms that work to conserve optimally moisture. Evolution does not specifically predict the development of camels, or true xerophyte plants, but any animals or plants that make their permanent home in the Sahara (or other extremely arid areas) will necessarily show water-conserving metabolisms.A scientific theory is a hypothesis based on a scientific topic.
Probably because they're very scientific, rely upon the hypothetico-deductive method, and have stood against disproof for many years.
A hunch is unsubstantiated. Scientific theory is theory in which an idea or even a hunch has been thouroughly tested- thru a hypothesis, testing the hypothesis, and results based on the scientific method. It is supported by other experiments and generally accepted by professionals in the field
It is accepted if the data support it.
If you develop an experiment that truly demonstrates that the hypothesis is wrong*, then the hypothesis will lose its acceptance in the scientific community.* Such an experiment would have to be repeatable by other scientists AND accepted by interested scientists as a proof that the hypothesis is wrong.
All experiments are based on hypothesis that has to be tested for truth. All scientific experiments therefore follow a logical methodology to arrive at a conclusion that must have a universal result that becomes universal accepted truth in Scientific experiments. It is necessary to follow the universal methodology by collection of the data for analysis to determine the elements or functional relationship in the experimental process. It is similar to any mathematical function that proceeds from one step to the next with the application of a universal formula that is written when solved.
For a hypothesis to be put forward as a scientific hypothesis, the scientific method requires that one can test it. A working hypothesis is a provisionally accepted hypothesis proposed for further research.
A conclusion sums up all your observations,inference, and hypothesis in the experiment based on the data collected. This is to prove whether your hypothesis is accepted or rejected.
A conclusion is accepted if its Results can be duplicated in any Lab, anywhere.
The scientific method is a scientific method for systematically acquiring new knowledge. The scientific method is typically applied to experiments, involving taking a hypothesis and using it to get applicable results.
when there s proof to back it up with evidence or an experiment to test the hypothesis

No. Not being able to prove something is NOT the same as it being true.
