# Normal Curve

From Elsmar Cove Quality Assurance and Business Standards Wiki

The familiar Normal Distribution "bell curve". The mathematical expression for the normal curve is y = (2π)-_e-x2/2. The normal curve is symmetric around the point x=0, and positive for every value of x. The area under the normal curve is unity, and the sd of the normal curve, suitably defined, is also unity.
