Gan L3: Gaussian Probability Distribution 3 n For a binomial distribution: mean number of heads = m = Np = 5000 standard deviation s = [Np(1 - p)]1/2 = 50+ The probability to be within ±1s for this binomial distribution is: n For a Gaussian distribution: + Both distributions give about the same probability! Central Limit Theorem l Gaussian distribution is important …
The Truncated Normal Distribution
people.sc.fsu.eduBecause the standard normal distribution is symmetric about the origin, it is immediately obvious that mean(˚(0;1;)) = 0. The variance of a distribution ˆ(x), symbolized by var(ˆ()) is a measure of the average squared distance between a randomly selected item and the mean. Assuming the mean is known, the variance is de ned as:
Cumulative Distribution Functions and Expected Values

The cumulative distribution function F(x) for a continuous RV X is defined for every number x by: For each x, F(x) is the area under the density curve to the left of x. F(x)=P(X≤x)=f(y)dy −∞
