Definition

A z-score, also known as a standard score, is a statistical measure that indicates how many standard deviations an individual data point or observation is from the mean of the dataset. It allows us to compare and interpret values in different datasets by measuring their relative position within the distribution.

This definition is part of Fiveable's AP Psychology review, which also has guided practice questions.
