The z-score table is used to find the probability that a random variable from a standard normal distribution will fall below a certain value. In this article, we will learn about the Z Score Table in sufficient detail and also learn how to use the Z Score Table in numerical problems. A standard normal table , also called the unit normal table or Z table , is a mathematical table for the values of Φ, which are the values of the cumulative distribution function of the normal distribution . It is 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 . Since probability tables cannot be printed for every normal distribution , as there are an infinite variety of ... A standard normal table is a mathematical table for the values of Φ, the cumulative distribution function of the normal distribution . It is 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 . Find the percentage of values below a given z-score in a standard normal distribution .
