> I don't know what you mean by the "distribution of the standard deviation."  Wouldn't your population have just ONE standard deviation, which you can get with the std() function?  How are you having more than one standard deviation?  Do you not have the original individual observations and instead have just the stats from some number of *sets* of observations?

Certainly, the population has one standard deviation, but as it is unknown, we can speak of its distribution based on the known info.
