Fact ;something that has happened actually and is universal and can not be changed
opinion ;it is not universal ,it varies from person to person
inference ; a conclusion derived from a given situation on the basis of one's own ideas
The term fact refers to something that actually exists or can be verified. However, Inference is the process of deriving a conclusion not only based on facts but also based on human perceptions, logic, statistical methods etc.
Inference:it is something you think.
Fact:it is something that has been proved correct
Inference refers to the act or the process of drawing logical conclusions from premises that are known or that are assumed to be true. It could refer to the act of reasoning based on factual knowledge or evidence. It could also mean something inferred. It is sometimes used to imply a hint or suggestion.
It could refer to the act of moving from statistical sample data to forming generalizations typically with specific calculated degrees of certainty. Inference is a topic that that has been incorporated into a number of different fields such as logic, cognitive psychology, statistics and artificial intelligence. Reasoning is a related field which includes sub areas like abductive reasoning, deductive reasoning, inductive reasoning and retroductive reasoning.
Synonyms for the same include the terms illation, deduction, conclusion and consequence.
The reasoning involved in drawing a conclusion or making a logical judgement on the basis of circumstantial evidence and prior conclusions rather than on the basis of direct observation is called as inference.
The information acquired by the scientists from their observations is in the form of scattered facts. These scattered set of facts cannot provide meaningful scientific knowledge. After considerable thoughts, these facts are carefully arranged and properly classified. Correlating the knowledge thus acquired with the knowledge, we already have; we try to think of tentative solution to explain the observed phenomenon. This tentative solution is called a hypothesis.
The validity of hypothesis is then, tested through the results obtained from experiments and by discussion among the scientists. As a result of this discussion a hypothesis may be accepted or discarded. The accepted hypothesis then takes the form of a theory. An appropriate theory not only predicts new facts, but also interlinks different natural phenomenon. A theory when repeatedly gives the same results after experimentation and offers correct explanation of the scientific facts; it then becomes a law or a principle. It is understood that a law or a principle is never rejected until and unless new or contrary information is s given on the basis of experimentation.
It has been observed that all hypotheses do not take the form of theories and all theories do not become laws. Some of the theories may be based upon strong arguments but they may not be supported by the experimental work due to unsuitable conditions. Whereas, occasionally a hypothesis may become law without any experimentation. A particular example of this is Avogadro's hypothesis, which has been accepted as law without any experimental support.
It means to find the information you know for example my mum never stops telling me what do do I know that the mum never stops telling someone what to do because it says it in the text.
I know I am SMART thanks
