A bell curve is a human-made graphical visualization that depicts the normal (Gaussian) probability distribution as a symmetric, bell-shaped curve. Parameters: the mean (central tendency), the standard deviation (spread), and the domain over which the curve is rendered. The name derives from the curve's visual resemblance to a bell. Built to persist through scientific illustration, textbooks, statistical software, and data visualization tools. [formal: campana | substrate: mind | horizon: hours | explicit: yes | epoch: 0.01]

Definition
Why it is in scope
A bell curve is a human-made graphical representation created by statisticians and educators to visualize the normal distribution. Named for its characteristic bell shape, it maps the probability density function of a Gaussian distribution as a symmetric curve, used to communicate statistical concepts and data patterns to audiences.

A bell curve is a specific kind of plot that visualizes a normal distribution as a symmetric bell-shaped curve. A competent speaker would call a bell curve 'a plot'. Files against the nearest general kind (plot).

A bell curve is the visualization of the normal distribution — remove normal distribution and the bell curve concept loses its referent entirely. The bell curve HAS NO CONTENT without the distribution it depicts. This is a constitutive dependency, not just historical association.
