How to determine whether the results of an experiment are valid?

Whenever we perform an experiment, we take various points, methods and supplies in consideration. An experiment can be provided by various means but the results are always the same providing there is no error in the instruments used or during the performance of the experiment, there has been no negligence. So, repeating an experiment will give us the same results as before. Hence, repeating the experiment is a good way to identify whether the results are valid as the results will be the same after the repetition.
