It is important to be able to test the hypothesis because testing your hypothesis is how you prove or disprove your theories. If it is disproved then you can change your hypothesis.
Not technically, you can disprove it. And you can narrow the probability of the null hypothesis but proof by experimentation alone is not possible.
Scientists first create an hypothesis. They develop methods to prove their hypothesis. In order for other scientists to replicate the findings and prove or disprove another scientist's outcome, the original scientist MUST describe the methods used and the findings.
When scientists perform experiments they don't just do it for reason, they do it to collect evidence to disprove or prove a hypothesis, which is basically a scientific statement that can be proved/disproved. If a hypothesis is proved, generally further tests are conducted around it to build up evidence that can eventually turn it into a theory.
"A hypothesis is a proposed answer to a question. To answer the question raised by your observations, the hypothesis must be testable." it means that you need to be able to prove that your hypothesis is true or not by creating an experiment and collect/analyze the data
be testable
To prove the hypothesis. To disprove the hypothesis.
An experiment can prove or disprove a hypothesis.
conducting experiment
Your hypothesis is supported by the data. You cannot prove a hypothesis because somebody may do some other experiments and disprove it eventually. You can only disprove a hypothesis or indicate that it is supported by the data.
That depends on the result of the experiment. The experiment is a way to test a hypothesis, and it's completely fine if the experiment disproves the hypothesis. Ideally, though, the experiment will support the hypothesis.
not only to prove a hypothesis, but disprove it as well
as many as needed to prove or disprove it
