A hypothesis is a tentative explanation that can be tested by further investigation. A theory is a well-supported explanation of observations. A scientific law is a statement that summarizes the relationship between variables. An experiment is a controlled method of testing a hypothesis.
Is a hypothesis true or correct?
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. For example, relativity has been tested many times, so it is generally accepted as true, but there could be an instance, which has not been encountered, where it is not true.

A theory is an explanation of the natural world and the universe. It explains facts that have already been proven true and is supported by data. A theory can be repeatedly tested and verified, and if proven true, makes the theory even stronger. … This is why theories are much more reliable than hypotheses.

What are the 3 required parts of a hypothesis?

What do you mean by working hypothesis?
A working hypothesis is a hypothesis that is provisionally accepted as a basis for further research in the hope that a tenable theory will be produced, even if the hypothesis ultimately fails.
What is the example of prediction?
