- Define the variables.
Is hypothesis correct if yes why if no why?
Upon analysis of the results, a hypothesis can be rejected or modified, but it can never be proven to be correct 100 percent of the time.

If there is no experimental test to disprove the hypothesis, then it lies outside the realm of science.
How is a theory different from a hypothesis?
In scientific reasoning, a hypothesis is an assumption made before any research has been completed for the sake of testing. A theory on the other hand is a principle set to explain phenomena already supported by data.
