Use the following format to find a z-score: z = X - Î¼ / Ï. This formula allows you to calculate a z-score for any data point in your sample. 1  Remember, a z-score is a measure of how many standard deviations a data point is away from the mean.2  In the formula X represents the figure you want to examine.his will start out the calculations for a z-score. 1  For example, in our sample of tree heights we want to find out how many standard deviations 7.5 is from the mean of 7.9. 2  Therefore, you would perform the following: 7.5 - 7.9.
To calculate a z score, you just divide the scores deviation from the mean by the standard deviation. In our example, if your consumption is 1000 Calories more than the mean and the standard deviation is 100, then your z score is 10, because (4000 - 3000) / 100 = 10. But if the standard deviation is 1000 then your z score would be 1. A z score is the number of standard deviations a data point is away from the mean. For a population of scores: .
