The formula for calculating a z-score is is z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.

The z-score formula is given as: z = (x – μ)⁄σ. Where z is the z-score, x is the raw score, μ is the population mean, and σ is the population standard deviation. We can also calculate the z-score for a sample of data. To do so, we replace μ with x̄ (the sample mean) and replace σ with S (the sample standard deviation).

Z-Score: Definition, Formula and Calculation ; z = (x – μ) / σ; = (190 – 150) / 25 = 1.6. ; z = (x – μ) / (σ / √n); = (70 – 65) / (3.5/√50) = 5 / 0.495 = 10.1.

The step-by-step z-score calculator calculates a z-score based on the z-score formula. First, enter values for the mean, standard deviation, and data value.

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.
