Bell Curve (The Bell Curve)

"The Bell Curve" refers to a graph shape called a normal distribution, which shows how most data points cluster around an average value, with fewer points as you move further away. In context, it’s often used to describe the distribution of IQ scores, where most people score around the average, and fewer score very low or very high. This shape resembles a bell, hence the name. It helps visualize how traits like intelligence vary within a population, highlighting that extremes are less common than middle-range scores.
