What a bell curve is.
A bell curve is a symmetric distribution with most values near a central average and fewer values farther from it. It is commonly used as a visual model of a normal distribution for continuous measurements such as scores, times or manufactured dimensions.
A bell-shaped curve is an approximation, not a default for every dataset. Check the observed data for skew, several peaks, bounds or outliers before using one to summarize a real population.

Common questions
What is a bell curve?
A bell curve is a symmetric, peak-shaped graph used to represent a normal distribution, with most values near the center.
When should I use a bell curve?
Use one for a continuous measurement when the observed values are reasonably unimodal and symmetric, or to teach the normal distribution.
What do the ends of a bell curve show?
They show less common values farther from the center of the distribution.
Is every dataset normally distributed?
No. Many datasets are skewed, multi-peaked or bounded and should be plotted in a form that reflects their actual shape.
