The body of the table contains the corresponding cumulative probabilities. 5 sits half a standard deviation below it.
How to Read Z Table Examples
For example, a z-score of 1. This value is the cumulative probability, or the area under the curve to the left of your specific z-score, which is the primary metric for statistical inference.
Understanding the Standard Normal Distribution The foundation of reading a z table is a solid grasp of the standard normal distribution, a specific instance of the normal distribution characterized by a mean of zero and a standard deviation of one. The formula for calculating it is (X - μ) / σ, where X is the data point, μ is the mean, and σ is the standard deviation.

Conversely, negative z scores represent values below the mean, yielding probabilities less than 0. To read a z table effectively, you first locate the row corresponding to the z-score’s integer and first decimal, then trace across to the column marked by the second decimal.
