Answer:
A good procedure is so detailed and complete that it lets someone else duplicate your experiment exactly! Repeating a science experiment is an important step to verify that your results are consistent and not just an accident. For a typical experiment, you should plan to repeat it at least three times (more is better).

Answer:
We should do experiments at least two to three times because of the following reasons-
- Repeating an experiment several times helps identify whether the results was a fluke or the norm.
- It aids in avoiding rash decisions based on insufficient evidence.
- The number of repetitions is determined by a variety of factors, including the distribution of the data and the availability of resources.
- Three repetitions is typically a decent starting point for examining data distribution.
- Experimenting over and again is normal scientific practice in most domains.
- The exceptions are mainly when the magnitude and cost of the tests make it impracticable.
- For instance, medicine trials for a rare medical ailment, large-scale sociological experiments, and observations of unusual events in astronomy.
- Repeated trials are when you repeat a measurement at least three times, usually five, but the more the merrier.
- When you measure anything only once, the chances of getting an accurate result are substantially reduced.
- However, if you measure it numerous times, you may average the results and get a value that is considerably closer to the truth.
