You all got it wrong. Standard deviation is...

a) how far off you are from your target in darts.
b) how many drinks you've got left before you pass out.
c) how far the 'fire for effect' barrage is from hitting the obvious target.
d) completely irrevelant to anything we REALLY want to talk about (C'mon: Conversation about math or the next FIFA champs, which hopefully be Germany again)

I hate math. I work with visual geometry mostly.
If I cut this post and let it fall will it miss all the stuff I don't want to break?
That kind of thing.
:O:

Imagine the surprise on faces the day I was not at work.
Some cables were cut that no one bothered to look at closely.
Results were a building that shifted and leaned 2" in a Northernly direction!

The eyeball is a wonderful thing.:up:
