WebIt is calculated by subtracting the population mean from an individual raw score and then dividing the difference by the population standard deviation. This process of converting a raw score into a standard score is called standardizing or normalizing (however, "normalizing" can refer to many types of ratios; see normalization for more). WebA z-score measures exactly how many standard deviations above or below the mean a data point is. Here's the formula for calculating a z-score: z=\dfrac {\text {data point}-\text {mean}} {\text {standard deviation}} z = standard deviationdata point − mean.
