Splet15. 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.

The sign tells you whether the observation is above or below the mean. For example, a z-score of +2 indicates that the data point falls two standard deviations above the mean, while a -2 signifies it is two standard deviations below the mean. A z-score of zero equals the mean. hbo the vow castSpletClick "Select PDF files to convert" to open the file chooser. Drag and drop pdf file (s) directly onto ezyZip.
