Standard Normal Distribution (Z) Table

The Z table shows probabilities (areas) under the standard normal distribution curve for given z-scores. It is used to find the probability of a value falling within a specific range in a normally distributed dataset.

How to Use the Z Table

  1. Find the z-score's ones digit and first decimal place in the leftmost column
  2. Find the second decimal place in the top row
  3. The intersection gives you the probability
  4. Hover over any value to see the shaded area in the distribution chart
