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