Statistics For Dummies, 2nd Edition. If a statistical data set has a normal distribution, it is customary to standardize all the data to obtain standard scores known as z-values or z-scores. The distribution of z-values takes on a standard normal distribution (or Z-distribution). The standard normal distribution is a special normal distribution with a mean equal to 0 and a standard deviation equal to 1. A standard normal (Z-) distribution has a bell-shaped curve with mean 0 and standard deviation 1. The standard normal distribution is useful for examining the data and determining statistics like percentiles, or the percentage of the data falling between two values.
