Not sure
The scientists often revise the hypothesis.
Very often. Scientists make a lot of mistakes. Cause they don't do some of their experiments with love.
A scientific theory is just a hypothesis that has stood the test of repeated experimentation. A hypothesis is a wild guess, and the more fundamental you want to make your hypothesis, the more wild it becomes. A scientific theory can be invalidated by a single experiment, but can never be proved no matter how many experiments are conducted. It's often pointed out that one of the most important jobs of real scientists is to work to DIS-prove the current theories. The more that competent scientists are unable to disprove a theory, the more trustworthy and plausible the theory becomes.
Scientists are often trying to find out whether certain factors changed or remained the same.
Scientists do that because they are skeptical about other scientists' work. They do not usually believe what other scientists have concluded, so other scientists come up with a hypothesis (or simply state a question) as to contradict, or theorize why another scientists' work and conclusions are wrong. In short: Scientists are skeptical and do not believe what another scientist has come up with as a conclusion.
If I recall the Scientific Method, scientists first develop a theory, then conduct tests to determine the validity of their theory, examine the test results, and often need to readjust elements of their theory, and start over conducting more tests and, if they have proof that their theory is true, then they need to have it duplicated by another independent scientific lab before they can publish their findings. (This is a very brief overview!)
Scientists often repeat scientific investigations to verify that the results for a hypothesis or a group of hypotheses are correct. This can lead to a scientific theory.

All shoes are made differently, and will often be sized differently. But has a general rule of thumb, a girls shoe size will often be 2 sizes smaller in a boys shoe.
