Answer: Each trial was repeated several times during the experiment.
A scientific design refers to a scientific plan or methodology, which needs to be followed to perform a experiment so as to obtain accurate and appropriate result matching with the situation of the hypothesis. Each trial was repeated several times during the experiment best describes an experiment that had a good scientific design because trials in an experiment brings either concordant or consistent results or inconsistent results.
