The "Bell Curve" is a graphical representation of a normal distribution, which is a common way to show how data points are spread out. In this curve, most values cluster around the average, creating a shape that resembles a bell. The highest point of the curve represents the mean, median, and mode of the data set, while the tails on either side show the less frequent extreme values. This concept is widely used in statistics and can apply to various fields, including psychology, education, and economics. For example, standardized test scores often follow a bell curve, where most students score near the average, and fewer students achieve very high or very low scores.
