- The standard normal distribution is the normal distribution that has a mean of zero and a standard deviation of one. The normal random variable of a standard normal distribution is called a standard score or a z-score. The normal random variable X from any normal distribution can be transformed into a z score from a standard normal distribution via the following equation: z = (X - μ) /
