    Does repeating an experiment make the mean more accurate?
    Repeating experiments has four major uses:
    1) Repetition reduces the likelihood of errors or anomalous results (verification)
    2) Scientists repeat others' experiments to verify the accuracy of the findings (peer review)
    3) Repeating an experiment allows a person to refine the results or simplify the methodology
    4) Scientists will often repeat experiments in order to study why it is that experiments bring about the results they do

    While the results might be more accurate by taking an average or discounting anomalous data. the key thing that repetitions increase is the reliability.
