Standard normal table the standard normal table to find probabilities. Normal distributions are symmetrical, bell-shaped distributions that are useful in describing real-world data. The "standard" normal distribution, represented by the letter Z, is the normal distribution having a mean of 0 and a standard deviation of 1. If "X" is a random variable from a normal distribution with mean μ and standard deviation σ, its Z-score may be calculated from X by subtracting μ and dividing by the standard deviation: For the average of a sample of size n from some population in which the mean is μ and the standard deviation is
