The z-score can be calculated by subtracting the population mean from the raw score, or data point in question (a test score, height, age, etc.), then dividing the difference by the population standard deviation: z = x - μ σ where x is the raw score, μ is the population mean, and σ is the population standard deviation. WebbThe Z-Score Calculator uses the following formula: z = (x - μ) / σ. Where: z is the standard score or Z-score, x is the raw score to be standardized, μ is the mean of the population, σ is the standard deviation of the population. Z-Score Calculation Example.
