I have been asked find the average fluctuation in a certain value. But I don't know what that means. Say x fluctuates about a mean.

[tex](\overline{(\Delta V)^{2}})^{1/2}?[/tex]

But that's the root mean square fluctuation, which isn't the same. Then how about

[tex]\overline{\Delta V}[/tex]

now that's the average fluctuation right?

But if I only know the average value, and the root mean square fluctuations, then how can I find the plain old average fluctuation from that?
