Normal Distribution and Standard Normal

Characteristics of a Normal Distribution · Approximately 68% of values in the distribution are within 1 SD of the mean, , above or below P

A standard normal distribution has a mean of 0 and standard deviation of 1 This is also known as the z distribution You may see the notation (N(mu, sigma

normalization A continuous random variable Z is said to be a standard normal random variable, shown as Z∼N, if its PDF is given by fZ=1√2πexp{−

binomial distribution A normal distribution is completely determined by its mean μ μ and its standard deviation σ σ , which means there are an infinite number of normal distributions
