The results of a scientific investigation either support or do not support a claim; they do not offer conclusive reports.
<h3>What is an experiment?</h3>
An experiment is a test under controlled conditions to either demonstrate a known truth, examine the validity of a hypothesis, or determine the efficacy of something previously untried.
Prior to experimentation, a hypothesis must be constructed, which is a testable prediction on the outcome of the experiment.
However, a hypothesis cannot be proven conclusively to be true but can only be accepted or not accepted.
Therefore, the results of a scientific investigation either support or do not support a claim; they do not offer conclusive reports.
