Web12 mei 2024 · A z -score is a standardized version of a raw score ( x) that gives information about the relative location of that score within its distribution. The formula for converting a raw score into a z -score is: (4.2.1) z = x − μ σ. for values from a population and for values from a sample: (4.2.2) z = x − X ¯ s. Web20 dec. 2024 · The population mean. 𝜎. The population standard deviation. If you know these three things, calculating a Z-score is easy. In the z-score formula, you simply subtract the population mean from your raw score and divide by the population standard deviation. \text {Z-Score}=\frac {x-\mu}\sigma Z-Score = σx−μ.
