What does a normal distribution graph resemble?

A normal distribution graph resembles a bell-shaped curve because it visually represents how data points are normally distributed around a central mean. In a normal distribution, most values cluster around the mean, and as you move away from the mean in either direction, the frequency of data points decreases symmetrically. This creates the characteristic bell shape, which is wide and rounded at the top and tapers off symmetrically on either side.

The properties of the normal distribution make it a fundamental concept in statistics, particularly because many statistical tests and confidence interval calculations are based on the assumption of normality. Understanding this shape is essential for interpreting data and applying statistical methods effectively.
