Default Re: What exactly is standard deviation?
Yes that is what I was referring to. I only got as high as Pre-Cal Honors in HS, so I can't do that math, but I'm assuming

CI's are constant for any event?
And that the event itself defines what it's standard deviation is? For instance, since 68% of people's IQ score falls between 85-115, then 15 is determined as the standard deviation, right?

Thanks for the help.
