The mean corresponds to the z-score of 1
SpletZ-Score Formula When calculating the z-score of a single data point x; the formula to calculate the z-score is the difference of the raw data score minus the population mean, divided by the population standard deviation. z = x − μ σ z = standard score x = raw observed data point μ = population mean σ = population standard deviation. SpletStep 1) Transform original raw scores into z-scores using the formula: z = (x - μ)/σ. Step 2) Change each z-score into an X value in the new standardized distribution using the …
