## Z-Score Calculator

The z-score is a statistical method that indicates how many standard deviations a value is from the mean. It has a variety of math and statistics applications. It is calculated using the following formula:

$$z = \frac{X - \mu}{\sigma}$$

Where $$X$$ is the value or score at issue, $$\mu$$ is the average, and $$\sigma$$ is the standard deviation.
