Re: I feel like an idiot here but I have a question about this
Standard deviation.. hmm..how to explain. There are 3 steps to SD, each diveded equally. Think of a bell curve. If you were cut it in half then divide it into 3 equal parts then combine it again you should get the idea. 66% of the average + st.dev will fall in the middle 2/3rds of the bell curve. 99% of you avergae +st.dev+st.dev will fall in the majortiy of the bell curvem and the last 1% is the third step.
So, if your AVERAGE W$SD is 50% with a ST.Deviation of 10% we can say that
66% of the time your W$SD is between 40% and 60%
99% of the time your W$SD is between 30% and 70%
100% of the time your W$SD is between 20% and 80%
if you graph it out you should see a nice bell curve
