Find the raw score corresponding to z −3

WebYou shouldn't be getting the standard deviation or the mean from a Z-table. The Z-table assumes a mean of 0 and a standard deviation of 1 (hence why we calculate a z-score before going to the table). The table has two uses: 1. Calculate a z-score and find the probability under the curve. 2. Look up a probability and find the z-quantile. 2 comments WebFeb 15, 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.
