What Is a Bell Curve in Math and Science? - ThoughtCo
Aug 12, 2024 · A bell-shaped curve refers to the shape created when a line is plotted using the data points for an item that meets the criteria of normal distribution. The center of a bell curve contains the greatest number of a value and therefore is the highest point on the arc of the line.
