Z TABLE provides Z score tables and normal distribution tables to help you find the area under the bell curve for any Z score. Learn how to use the Z score formula, how to read the Z tables, and how to compare values to the mean.
The z-table is built based on the standard normal distribution. However, if you need to calculate the probability for a non-standard normal distribution, you can use the following z-score formula. z = 𝑥 - μ. σ. Where: 𝑥 - the value. z - the z-score. μ - the mean. σ - the standard deviation.
A standard normal table, also called a Z table, is a mathematical table for 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.
Find the Z-score, P-value, and probability for any test value, mean, and standard deviation. Browse the negative Z table for common Z-scores and their corresponding probabilities.
Find the area to the left of any z score in the standard normal distribution using this table. The table shows the z score and the corresponding area value for negative and positive z scores.
Learn how to use a z-table, also known as the standard normal table, to find areas, percentiles, and p-values for z-tests. A z-table provides the area under the curve to the left of a z-score for a normal distribution.
Find the area under the standard normal curve for any value of Z. The table shows the percentage of the population that is less than or equal to Z, or greater than Z, for different values of Z.
