Can z scores be used for non-normal distributions?

• Comparing individual values to a larger dataset

Imagine you have a dataset of exam scores, and you want to determine how well a particular student performed relative to their peers. A z score tells you how many standard deviations an individual value is away from the mean. The formula for calculating a z score is straightforward:

σ is the standard deviation
• Z scores are only used for statistical analysis: Z scores have practical applications in fields like quality control, medicine, and finance.
• Overemphasizing individual values
X is the individual value

A z score of 0 indicates that the value is equal to the mean.
