With this quiz and worksheet, you can review how to calculate and interpret Z-scores. Answer questions about the meaning of the term Z-score, the fastest way to find this score and what Z-scores measure.

Use these practice questions to assess your knowledge of:

- The standard place value to which a Z-score should be rounded
- A quick method for finding Z-score percentages
- What one-sided and two-sided Z-scores represent

**Interpreting information**- read and interpret information about the correct way to calculate Z-scores**Defining key concepts**- choose the right definition for the term Z-score**Distinguishing differences**- demonstrate that you know the difference between a one-sided and two-sided Z-score

For extra practice and to learn details about finding and using Z-scores, read the lesson called Using the Normal Distribution: Practice Problems. This lesson reviews:

- How Z-scores are related to standard deviation
- Clues for figuring out the direction of a data set
- The relative significance of positive and negative Z-scores
- Two real-world examples of how Z-scores are applied
