[Edited on 24-3-2011 by Panache] | What you say is not true. One result also has a meaning, but repeating and
averaging numerical outcomes establishes the meaning more firmly.
So, yes, it is good to repeat an experiment and take average results, but saying that the outcome of a single experiment has no meaning is too bald.
