Theories
false
its absolute value is greater than or equal to 1 and less than 10
A "law" contains absolute certainty or scientific truth. A theory is very close to being a law, but without the absoluteness. That is what a theory is. If you have a pretty good idea of how something in science might work you might form a hypothesis (hye-POTH-uh-suss). With enough additional proofs and evidence, a hypothesis may someday turn into a theory.
As for example: 2.75*10^6 means 2,750,000 by moving the decimal point 6 paces to the right
Science investigates difficult questions about unknown fields, and scientists are human, so it is inevitable that scientific findings will not be perfect. However, science works by investigating more and more, which means results get checked and rechecked with further findings. The reason some findings change is because they get corrected. This process of correction helps make science one of the most successful areas of human endeavor. The people who cannot be trusted are those who are always right.As more evidence accumulates, scientific findings become more and more certain. Theories that have withstood several decades of study may undergo more refinement of details, but it is almost inconceivable that they would be overturned completely.

If my memory of third grade serves me, that would be a theory. Theories are based upon observations (e.g.: Observation: That guy's left side looks limp. Theory: He had a stroke) and are not absolute, as until it is tested and proven, there is no way to tell for certain if a theory is true or not.
That is correct. If the result of an experiment cannot be replicated (repeated), the theory is weakened or overturned. In addition, results in general are not absolute as it is always possible something has been overlooked that would significantly alter the theory. For example, Newton's theory of gravity was considered to be very good, and explained the motions of the planets about the sun extremely well. Except for Mercury, whose motion did not fit Newton's model. Eventually Einstein developed a superior theory of gravity (general relativity), which accounted for the motion of Mercury.
All scientific theories are basically just consensuses of postulates to guide scientific research in a search for evidentiary proof. Consequently no theory is absolute fact. In the case of the Big Bang theory we also have the problem that we are trying to figure out what happened billions of years in the past, long before any human beings were around to observe those events directly. We have lots of astronomical observations which are relevant to this theory, but it is possible to imagine more than one way to interpret those observations. That said, you should also know that the evidence for the Big Bang theory is quite strong, and no one working in the field of cosmology has any serious doubt about it. It is very well supported. But it is not absolute fact. Nothing in science is taken as being absolute. For absolute truth, you must turn to religion.
Scientific knowledge is not absolute.
The mean absolute percent prediction error (MAPE), .The summation ignores observations where yt = 0.
a French philosopher: Thomas Hobbes
It is all doubtable, testable and open to disproof. This is the strength of the scientific method; it is a heuristic. It does not lead to absolute truth. There are some basic observations that are probably undeniable for all of time, but the more speculative or theoretical a scientific principle is, the more it is vulnerable to change or re-interpretation.
It means that the observations are all close to their mean value.
