Gaussian

A Gaussian, often called a "bell curve," is a way to describe data that clusters around an average value. Most data points are near the center, with fewer appearing as you move farther away. The shape of the curve is symmetric, meaning it looks the same on both sides. This pattern appears in many natural and social phenomena, like heights, test scores, or measurement errors. The Gaussian distribution is fundamental in statistics because it helps estimate probabilities and understand variability in data that naturally tends to follow this pattern.
