[edit] Use for standard error of the mean

In biology, or at least cell biology, it's common to use plus-minus to give the standard error of the mean for a variable. In a paper, you typically declare what you're doing in the methods section, so there's no ambiguity; it is different to practice in other fields, though.

And yes, this does mean we're effectively using 67% confidence limits. Sigh.

[edit] Purple box added

For transparency, consensus-building purposes, I wish to make editors aware that I have added the purple box, with "±" depicted, to the article (diff). If there are any qualms or enquiries regarding my change, please feel free to discuss with me on my talk page, or below (NB, you might wish to drop me a note of any discussion ongoing here, at my talk page).

I changed the font of plus-minus in purple box to separate the signs from each other. User: unregistered
