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.
Example of calculating an upper-tailed p-value. Now suppose you do a one-sample upper-tailed z test and the resulting test statistic is 1.785 (ts= 1.785). You want to calculate a p-value for the z test. 1  Choose. 2  Choose Cumulative probability. 3  If necessary, in Mean, enter 0 and, in Standard deviation, enter 1. 4  Choose Input constant and enter 1.785. 5  In Optional storage, enter K1. 6  Choose. 7  In Store result in variable, enter K2. 8  In Expression, enter 1-K1. 9  Choose. 10  Choose K2.
