What is Bell Curve ?
‘Bell Curve’ is the term given for the graphical representation of a Gaussian distribution. It is named so since it is a curve that looks like a bell.
It is significant in the field of HR since the theory that, if you map the performance of the employees on a graph, most of it will fall into a specific range similar to the Bell Curve.
The Bell Curve represents a standard distribution in mathematics, wherein, an average rating or score, increases in number towards the top of the ‘bell’ with the lesser scores and the higher scores evenly distributed towards the lower end of the ‘bell’.
This helps in multiple fields like statistics, social sciences and even HR by helping in the development of performance tests.
