WebMar 14, 2024 · To find the Z-score, you subtract class mean (50 percent) from the individual score (80 percent) and divide the result by the standard deviation. If you want, you can convert the resulting Z-score to a percentage to get a clearer idea of where you stand relative to the other people who took the test. Why Are Z-Scores Useful? WebThis simple calculator allows you to calculate a standardized z -score for any raw value of X. Just enter your raw score, population mean and standard deviation, and hit "Calculate Z".
