WebNov 15, 2024 · Here is a formula for calculating the z-score: z = (x- μ)/σ where x – individual value μ – mean σ – standard deviation. Interpretation of the formula: Subtract the mean of the values from the individual value Divide the difference by the standard deviation. WebThe resulting z-score measures the number of standard deviations that a given data point is from the mean. The average of every z-score for a dataset is zero. A negative z-score indicates a value less than the mean, and a positive z-score indicates a value greater than the mean. Z-Score Formula =STANDARDIZE (x, mean, standard_dev)
