Normalization, also known as the Bell Curve, is a statistical method used to represent the distribution of data. It is a common practice in HR to assess employee performance and determine ratings based on a bell curve distribution. This method helps HR professionals compare employees' performance relative to their peers and set performance standards within an organization. The bell curve assumes that performance levels among employees follow a normal distribution, with most employees falling in the middle range and fewer employees falling in the high and low ends of the curve.
