The normal distribution is symmetrical about its mean: The Standard Normal Distribution. If Z ~ N(0, 1), then Z is said to follow a standard normal distribution. P(Z < z) is known as the cumulative distribution function of the random variable Z. For the standard normal distribution, this is usually denoted by F(z).
