Theory VS Hypothesis

A theory is a principle formed to explain the things already shown in data. 

A hypothesis is an assumption made before any research has been done. 

• A theory is a principle formed to explain the things already shown in data. Because of the rigors of experiment and control, it is much more likely that a theory will be true than a hypothesis.

• In scientific reasoning, a theory is supported by evidence: it's a principle formed as an attempt to explain things that have already been substantiated by data. 

• A theory, in contrast, is a principle that has been formed as an attempt to explain things that have already been substantiated by data. It is used in the names of a number of principles accepted in the scientific community, such as the Big Bang Theory. Because of the rigors of experimentation and control, its likelihood as truth is much higher than that of a hypothesis. 

•  Hypothesis is formed so that it can be tested to see if it might be true. 

• In scientific reasoning, a hypothesis is constructed before any applicable research has been done.

• In the scientific method, the hypothesis is constructed before any applicable research has been done, apart from a basic background review. You ask a question, read up on what has been studied before, and then form a hypothesis. 

• A hypothesis is usually tentative, an assumption or suggestion made strictly for the objective of being tested.
