Chapter 1: Descriptive Statistics and the Normal Distribution

Gaussian Distribution - an overview normal distribution If a set of n observations is normally distributed with variance σ2, and s2 is the sample variance, then s2σ2 has a chi-square distribution with n–1 normal distribution The standard normal distribution is so-called because its parameters are the units for their respective operations—the location is zero and the scale (

normalization The Probability Density Function for a Normal X ∼ N is: f X = 1 σ 2 π e − 2 2 σ 2 Notice the x in the exponent of the PDF
