The Z score formula, also known as the standard score, is a statistical measure that shows how many standard deviations an element is from the mean of a data set. The formula is as follows: Z = (X - μ) / σ, where X is the value of the element, μ is the mean of the data set, and σ is the standard deviation of the data set. This formula converts an element's value into a standardized score, allowing for easy comparison with other values.
