I'm a bit of a math dummy and trading dummy, if the truth be known, so I need a little bit of help.

I think I have a fairly good grasp of ATR, but I'm bit lost as to what standard deviation is in general and especially specific to this example:

If I want to take the Average Range of a pair over a 2 month period, say that is 148 pips and then calculate the standard deviation from the 148 pips. What exactly I am I calculating? Or to put another way, what am I looking at? Or What does this data point tell me?

If my math is right 68.2% is a standard deviation, so taking 68.2% of 148 pips = 101 pips. So what should this tell me?

Sorry, I can't think of how to word this better. Thanks in advance.
