Since someone else asked in jabber: The charts are made using Apple's Numbers application.
I had a bit of a pie chart / graph gimmick going for my posts during the war to take branch and some of mine looked similar.
The pie slices are "pulled out" like so.
Edit: Oh and GENTS are the slightly lighter green at ~98B. Ahem.
Cue 90s-style mac/windows flamewar.
Numbers has had standard deviation bars since version 2, released January 2009. He was merely asking how to use them. A first-time excel user would have the same question.
I like Pages but it's not so hot if I have to swap files with MS Office users. Numbers is OK I guess, it quite different from normal spreadsheet programs.
I'd recommend at least trying OpenOffice and LibreOffice. They're free and easy to uninstall so there's nothing to lose.
Don't forget about Google Docs.
That pretty much is 98% of office apps use on the Mac.
On the fringe there's also Zoho, another online office suite. There's a few good word processors out there, like CleanWriter Pro an AbiWord. But they tend to have specialized users but you might check them out.
I understand now. I don't think there is a simple way to do this (like the dragging technique.
You can probably get there using Numbers Functions.
I got part of the way for you. (Check the function in the upper left). Maybe you can figure out the rest. This is probably the "easiest" way to get these numbers. It may not be appropriate depending upon your final purpose.
I'm going to have to disagree (only partially, of course).
Numbers lacks some of the more "heavy duty" actuarial functions of Excel, but, based upon OP's description of "nothing too fancy" I have a feeling Number's extensive function capability will be able to reproduce much of their work in Excel.
I've also found that, at least from Numbers to Excel, these functions export perfectly.
