Standard Normal Distribution For negative z-scores subtract the value in the table from 1. The Standard Normal Distribution Table The standard normal distribution table provides the probability that a normally distributed random variable Z with mean equal to 0 and variance equal to 1 is less than or equal to z It does this for positive values of z only ie z-values on the right-hand side of the mean.
