What should the scientist do to best gain scientific understanding of this topic? Analyze the results, and change the experimental methods to retest the hypotheses in a different way.
Discard the faulty results that do not support the original hypothesis, and repeat the experiment using the same methods.
Analyze the procedural errors that took place in the experiment, and summarize these in a conclusion statement.
