Use the positive Z score table below to find values on the right of the mean as can be seen in the graph alongside. Corresponding values which are greater than the mean are marked with a positive score …

Here is the data behind the bell-shaped curve of the Standard Normal Distribution

Standard normal table In statistics, a standard normal table, also called the unit normal table or Z table, [1] is a mathematical table for the values of Φ, the cumulative distribution function of the normal …

A z-table, also called standard normal table, is a table used to find the percentage of values below a given z-score in a standard normal distribution. A z-score, also known as standard score, indicates …

Learn more about Z-scores, the Normal Distribution, and Probability Distributions. You can use z-score tables to find areas below, above, between, and outside z-scores. In some cases, solving these …

Dec 11, 2025 · The rows and columns of the table define the z-score and the table cells represent the area. For example, the z-score 1.50 corresponds to the area 0.9332, which is the probability that a …
