Quick Summary

The term "bell curve" refers to a symmetrical, bell-shaped graph that represents a normal distribution. This curve is also known as a normal curve. In a bell curve, most data points, or values, are clustered around the middle, which represents the average value and the most common value. The shape is described as "bell-shaped" because it resembles a bell.123

A normal distribution is a probability density function that approximates the distribution of many random variables. It is defined by its mean ((\mu)) and standard deviation ((\sigma)). The standard deviation is a statistical measure of how spread out numerical values are from their mean.45

The graph is the familiar bell-shaped Gaussian “normal” curve that typically arises when the random variable is the sum of many independent, statistically identical random variables, in this case the many little pushes that add up to the total motion. The equation for this relationship is
