Measures standard deviations a data point is from the mean
Z=X−μσZ = \frac{X - \mu}{\sigma}Z=σX−μ
The data value
The mean of the dataset
The standard deviation of the dataset
Data point equals the mean
Value is above the mean
Value is below the mean
Allows comparison of data from different distributions
Used with Z-tables to find cumulative probability
Z<−3Z < -3Z<−3 or Z>3Z > 3Z>3
Standardises data for comparison across datasets
