Answer:
Testable prediction that gives direction to research.
Explanation:
A hypothesis is an explanation that can be accepted in a provisional way, but has the objective to provide sufficient guidance for further investigation.
It is also considered testable because it can be proven right or wrong, it means it is possible to be verified.
A researcher uses deduction to formulate a hypothesis and then forms a theory. It can be said that a theory is never proven when a theory holds only until some evidence comes forward to disapprove it.
In addition to explaining existing facts, a theory also enables scientists to forecast what observations they should expect to see if the theory is correct.
- Scientific hypotheses can be tested.
- A theory should be consistent with new data.
- If not, the theory is changed or abandoned.
The most comprehensive explanations for how the world functions are currently found in accepted theories. They have undergone extensive testing, are backed by numerous lines of evidence, and have shown promise in developing explanations and revealing new study fields.
But science is always evolving, and even hypotheses can alter.
