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 …

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, …

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

STANDARD NORMAL DISTRIBUTION: Table Values Represent AREA to the LEFT of the Z score. -3.9 -3.8 -3.7 -3.6 -3.5 . -3.4 -3.3 -3.2 -3.1 -3.0 . -2.9 -2.8 -2.7 -2.6 -2.5 . -2.4 -2.3 -2.2 …

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 …

This interactive Z table displays probabilities (areas) under the standard normal distribution curve for specific z-scores. It helps determine the probability of values falling within particular ranges …

Dec 11, 2025 · Look up the z value (two decimals) in the Z-table to get cumulative probability P ( Z ≤ z ) . If you need P ( Z > z) compute 1 - P ( Z ≤ z). For negative z use symmetry or the …
