Normal Law is just a "common sense" law
Normal Law known popularly as the "Bell Curve" or mathematically as the "Gaussian" Law is just a "common sense" law:
It describes mathematically the idea that extremes are rare and elements around averages more and more numerous. So Normal Law could obviously not be a half-circle nor a square but a bell curve.
To characterize the Bell Curve, we only need two parameters: a mean around which most of the population will be found and a standard deviation which impacts the distance between the average and the queues of the extremes.
Normal Law is represented mathematically by a Bell Curve

"Common sense" was in quote. The way Normal Law is generally explained at school through "Central Limit Theorem (CLT)" (see here http://statistical-process-control.blogspot.com/20 which is also one of my blogs ) so maybe my explanation above is not as clear as you would like but I was trying to making it more intuitive than the mathematical one.
>And lastly, you did not define what a rare event is.
Because this hub was not intended to be a full course on Probability as I'm not sure it really interests many people but maybe I will complete it one day upon your suggestion above :)
that guy just burned ur blog damn!!!!!!!!!!!!!!!!!!!
all i gota say is damn
This is one of the first things you will learn when you get to higher education
It just explains the general nature of the distribution of a normal data set.
Sometimes there is a tail in the normal distrbution, this represents a skew from the normal distribution
