Direct Link: Area/Variance = Constant
1)This shows a Direct Link between i - geometry and Normal Probabilities - Using : RV-sigma equation.
2) Variance = 1.16 makes Variance = to Constant : f = Area / Variance
3) This seems like this is redundant but it is not; actually this shows the direct relationship between values of a Square made from the i - geometry value 1.16.
