WebbBell Curve (Formula, Examples) Normal distributions come up time and time again in statistics. A normal distribution has some interesting properties: it has a bell shape, the mean and" A bell-shaped function or simply 'bell curve' is a mathematical function having a characteristic "bell"-shaped curve. These functions are typically continuous or smooth, asymptotically approach zero for large negative/positive x, and have a single, unimodal maximum at small x. Hence, the integral of a bell-shaped function is typically a sigmoid function. Bell shaped functions are also commo…
