Webb15 feb. 2024 · How to calculate. The formula for calculating a z-score is z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation. As the formula shows, the z-score is simply the raw score minus the population mean, divided by the population standard deviation. Figure 2. Z-score formula in a population. WebbStep 1: Calculate the mean of the data—this is \mu μ in the formula. Step 2: Subtract the mean from each data point. These differences are called deviations. Data points below the mean will have negative deviations, and data points above the mean will have positive deviations. Step 3: Square each deviation to make it positive.
