To make sure it is true.
If they didn't test an expirement multiple times, there is no way of proving if they made a mistake or not.
redo or retest the experiment
redo
it is important to experiment because you need to see what happens to it and if it happens differently then u will have to redo it.
Scientists will review their procedures and data to identify where the mistake occurred. They will make necessary adjustments, such as refining their methods or controlling variables better, before repeating the experiment to correct the error and obtain accurate results. Additionally, they may consult with colleagues or mentors for advice and guidance.
Depending on the size/importance of the experiment, they can either simply repeat as normal or if needed gather more resources for the experiments. Scientists always perform experiments at least three times, to make sure nothing is abnormal in an experiment.
you must repeat and redo the experiment
Observation and record keeping are important as you will need to redo an experiment many times to prove that it actually works.
No redo the experiment.
Test
Scientists redo each others experiments for accuracy. They want to make sure that they all get the same answer each time.
to make sure its correct
