Normal distribution table: A standard normal table (also called the

A standard normal table (also called the unit normal table or z-score table ) is a mathematical table for the values of ϕ, indicating the values of the cumulative distribution function of the normal distribution . Z-Score, also known as the standard score, indicates how many standard deviations an entity is, from the mean. Normal distribution to standard normal distribution : When working with the normal distribution , it can be useful to convert to the standard normal distribution , which has a mean of 0 and a standard deviation of 1. The z- table is built based on the standard normal distribution . 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 .
