Re: [office] Proposal: Error bar category standard-error

Correct.  

I know we've been having some debate
on the formula list on whether the preferred term is "normal"
or "Gaussian".   This seems to a difference between how
statisticians and physicists refer to it.  But I think we agreed that
"normal" was the preferred term.

David Wheeler, is this right?

Just to make sure I did understand that correctly:

What you propose is that we use the following description:

* Standard error (standard deviation of the mean) of a data series

  assuming a normal distribution

Is that correct?
