Normal Distribution and Standard Normal Distribution

Every score in a normally distributed data set has an equivalent score in the standard normal distribution This means that the standard normal distribution can

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{−

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

binomial distribution The sampling distribution of the mean becomes approximately normal regardless of the distribution of the original variable The sampling distribution of the
