Question

Why do modern scientists use repeated experiments to develop and test hypotheses?

Answer 1

The correct answer is that it makes the experiment error-free and more reliable.

Explanation:

Scientists now days perform the experiments several times to test hypotheses and develop it. The repeated experiments help in making experiments error-free and more reliable.

Repeated experiments also help in supporting the hypothesis or rejecting the hypothesis with accurate data acquired by several experiments.

Thus, the correct answer is it makes the experiment error-free and more reliable.

Answer 2

To make sure our answer is correct and accurate, we all need to solve multiple times. This process makes the accuracy of our answer more.

Scientists want a more accurate answer, so if they get the same result after multiple attempts, they have a very accurate answer. That makes it more believable.

That right there is the reason why they use multiple ways to test hypotheses.
