Learn how to use the Z score formula and the Z table to compare values to the normal distribution. Find out how to read the Z table and map Z scores to areas under the bell curve.
Find the Z value and the corresponding probability for any standard normal distribution using this interactive Z table and chart. Hover over the cells to see the details and examples of how to use the Z table.
Find the z-score, p-value, and probability for any test value, mean, and standard deviation. Browse the negative z-table and use the z-score calculator to compute z-scores and probabilities.
Learn how to use a z-table, also known as the standard normal table, to find probabilities, percentiles, and critical values for z-scores. See examples, charts, and methods for different types of z-tests and problems.
A standard normal table, also called a Z 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.
A PDF file that shows the z score and the corresponding area under the standard normal curve. The z score is the number of standard deviations above or below the mean of a normal distribution.
Find the area under the standard normal curve for any z value using this table. The table shows the percent of population between 0 and z, less than z, or greater than z.
