- 10: The Normal (Gaussian) Distribution - Stanford University
Why the Normal? Common for natural phenomena: height, weight, etc Most noise in the world is Normal Often results from the sum of many random variables Sample means are distributed normally

Figure 1: Normal distribution with various choices of μ and σ Normality? The central limit theorem (CLT) states that the sum of a large number of independent random variables tends to be approximately normally distributed Real world data often appears approximately normal Normality? Diffusion of a substance in a liquid or gas

Troponin-I is an early and late marker for acute myocardial infarction (increases above upper limit occur 3-8 hours post-infarction: Peak levels occur 8-24 hours after infarction; values return to normal within 4-8 days) The diagnostic cut-off for acute myocardial infarction (AMI) is 0 3 ng mL No additional action unless exposure source change

Standard Normal tables give probabilities - you will need to be familiar with the Normal table and know how to use it First need to calculate how many standard deviations above (or below) the mean a particular value is, i e , calculate the value of the “standard score” or “Z-score”

5 The Normal Distribution (Ch 4 3) The normal distribution is probably the most important distribution in all of probability and statistics Many populations have distributions that can be fit very closely by an appropriate normal (or Gaussian, bell) curve
- Properties of Normal distribution - James Madison University
Normal or Gaussian distribution is a symmetric distribution Normal distribution has two parameters: mean (μ) the location parameter and standard deviation (σ), the spread parameter If a X is a continuous random variable with mean μ and standard deviation σ, then it is written as, X ~ N(μ , σ)
