Subject: 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?
