The simplest case of a normal distribution is known as the standard normal distribution or unit normal distribution This is a special case when 0 displaystyle mu 0 and 1 displaystyle sigma 1 and it is described by The mean for the standard normal distribution is zero, and the standard deviation is one. The transformation z = x − μ σ x − μ σ produces the distribution Z ~ N (0, 1). The value x in the given equation comes from a normal distribution.

Standard Normal Distribution FormulaStandard Normal Distribution. A standard normal distribution has a mean of 0 and variance of 1. This is also known as a z distribution. You may see the notation \ (N (\mu, \sigma^2\)) where N signifies that the distribution is normal, \ (\mu\) is the mean, and \ (\sigma^2\) is the variance. The standard normal distribution also called the z distribution is a special normal distribution where the mean is 0 and the standard deviation is 1 Any normal distribution can be converted into the standard normal distribution by turning the individual values into z scores
