We say the data is "normally distributed": The Normal Distribution has: mean = median = mode. symmetry about the center. You can see a normal distribution being created by random …

Nov 4, 2025 · The normal distribution is a continuous probability distribution defined by its mean μ and standard deviation σ, forming a symmetric bell-shaped curve.

Everything you want to know about the normal distribution: examples, formulas and normality tests in simple language with clear illustrations.
