[O] pstdev() syntax?

[Jude DaShiell]

I used a $+TBLFM: $2=pstdev(@<..@>) and am none too sure that's even 
correct syntax to calculate a population standard deviation on column 2. 
What would be the syntax to make this operation also happen on columns 3-5 
as well?  I didn't get into spread notation of b2:b330 since I don't know 
the syntax for calculating a whole column in the spreadsheet format.
