Dear ElMaestro,

If the sample on which the mean and standard deviations are calculated is smaller than infinity :-) than the mean and standard deviations are also random variables and follow a specfic distribution (i.e. sampling distribution).

To be precise: The sampling distribution of a statistic is the distribution of that statistic, considered as a random variable, when derived from a random sample of size n.

best regards & hope this helps

Martin
