What a bell curve graph is.
A bell curve graph shows how values are distributed around a central average. In a normal distribution, most observations sit near the mean and the frequency falls away symmetrically toward both extremes.
It is useful for explaining a dataset’s centre and spread, whether the values are exam scores, fill weights or response times. Check the raw data before calling a distribution normal: distinct groups, outliers and skew can change the story.

Common questions
What is a bell curve graph?
A bell curve graph represents a normal distribution: values cluster around a mean, then become less common as they move farther from it.
How do I make a bell curve graph?
Describe the measured variable, its centre and spread, or provide grouped values. Include the unit and labels that a reader needs.
What do standard deviations show on a bell curve?
They show distance from the mean in units of the dataset’s spread. They help compare how unusual a value is relative to the rest of the distribution.
Can a bell curve show non-normal data?
It can plot grouped data, but a bell-shaped line should not imply normality if the values are clearly skewed or contain separate clusters.
