A bell curve, also known as a normal distribution, is a statistical graph that represents data distribution where most values cluster around the mean, creating a symmetric, bell-shaped curve. It is commonly used in performance appraisal, grading systems, and probability analysis. The highest point represents the average, while the curve slopes downward on both sides, indicating fewer occurrences of extreme values. Many natural and social phenomena, such as intelligence scores and employee performance, follow this pattern. In HR, bell curves help in performance evaluations by categorizing employees into high, average, and low performers, aiding in decision-making and resource allocation.
