Normal distribution (also called Gaussian distribution) is a continuous probability distribution where data is symmetrically distributed around a mean, forming a bell-shaped curve.

Most values cluster around the mean, and the probability of extreme values decreases smoothly as you move away from it.

Empirical Rule (68–95–99.7):
68% within ±1σ
95% within ±2σ
99.7% within ±3σ
