Normal Distributions

The Standard Normal Distribution • SOGA-Py normal distribution The normal distribution is also called the Gaussian distribution or bell curve A normal distribution has two parameters, the mean μ μ , and the variance σ2 normal distribution Any point from a normal distribution can be converted to the standard normal distribution with the formula z = standard deviation z for any

binomial distribution 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
