How to calculate area from z score
WebTo calculate z-scores, take the raw measurements, subtract the mean, and divide by the standard deviation. The formula for finding z-scores is the following: X represents the data point of interest. Mu and sigma represent the mean and standard deviation for the population from which you drew your sample. Web15 feb. 2024 · 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.

It is 0.15945 standard deviations below the mean. To check the results, you can multiply the standard deviation by this result (6.271629 * -0.15945) and check that the result is equal to the difference between the value and the mean (499-500). Both results are equal, so the value makes sense.
