H2 Maths 6.3 - Normal Distribution: Introduction and Properties

What you will learn

• Notation X ~ N(mu, sigma^2); mu is the centre and sigma^2 controls the width of the bell.
• Bell is symmetric about mu, so mean = median = mode = mu and each side carries 0.5 of the total area.
• Continuous distribution: P(X = a) = 0 for any single a; probability is area between two limits.
