The​ _______ represents the number of standard deviations an observation is from the mean.

The **z-score** (or **standard score**) represents the number of standard deviations an observation is from the mean.

Would you like to go into more detail or have any other questions?

Here are five related questions to deepen your understanding:

1. How do you calculate the z-score for a given observation?
2. What does a positive or negative z-score indicate?
3. How is the z-score used in hypothesis testing or probability?
4. What is the relationship between z-scores and the normal distribution?
5. How can z-scores be used to compare data from different distributions?

**Tip:** A z-score of 0 means the observation is exactly at the mean.

The _______ represents the number of standard deviations an observation is from the mean.

Learn how the z-score measures the number of standard deviations an observation is from the mean. This concept is vital in statistics for analyzing data in the context of the normal distribution and hypothesis testing. Suitable for students in Grades 10-12.
