Say if I have a sample space 2,3, and 5. I want to find by what percent points deviate from the mean. So I would take the standard deviation as follows.(adsbygoogle = window.adsbygoogle || []).push({});

2+3+5 / 3 = 3.33

(2-3.33)^2 + (3-3.33)^2 + (5-3.33)^2 / 3 = 1.55

(1.55)^(1/2) = 0.775

So we get a standard deviation of 0.775. So how do I turn the standard deviation into a plus or minus percentage?
