A standard normal table also called the "Unit Normal Table" is a mathematical table for the values of , the cumulative distribution function of the normal distribution. They are used to find the probability that a statistic is observed below, above, or between values on the standard normal distribution, and by extension, any normal distribution. 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. Since probability tables cannot be printed for every normal distribution, (there are infinite), it is common practice to convert a normal to a standard normal, and use a Z table to find probabilities.
