Scientists repeat experiments for reliability.  Experiments have to be repeated, since performing an experiment only once, does not prove a scientists theory on the experiment, which they develop by performing the experiment.  And then performing the experiment again or even many times to prove or disapprove their theories.  Btw, before an experiment begins, the scientist will make a hypothesis of what they believe will happen.  If proven correctly, they would then use those results they record throughout the experiment, from beginning to end to prove whether or not their hypothesis are correct or incorrect.  Click to let others know, how helpful is it

BASICALLY, I THINK THE ANSWER IS 1 OR 2 OR

Answer;

2.The scientific method only applies to repeated experiments.

Explanation;

  • For a scientific method or scientific experiment to be viable it should be repeatable and falsifiable. This means the scientific experiment should be such that it can be performed by other scientists and similar results are obtained.
  • It is therefore important for scientists to repeat the investigations of other scientists so as to see if the results are similar and also can ask questions about an experiment and be in a position to point out problems if the exist.
  • However, some variations in results are acceptable, but the results from different scientists should be similar and consistent, and if not then the experiment must be done again.
