Hello,

I am sure this is a very elementary question, but simply I do not know
the answer and hope someone else knows the answer.
My question is : 

      Why is "standard deviation" called "rms deviation" ?

I think they are exactly same.  However, only "rms deviation" seems
to be used in the molecular structure comparison literature.

Thank you very much for your time !
