WebThe z-score allows you to compare data from different samples because z-scores are in terms of standard deviations. A positive z-score means the data value is higher than average. A negative z-score means it's lower … Webb. To find the area to the right of z, use the Standard Normal Table to find the area that corresponds to z. Then subtract the area from 1. 3. Subtract to find the area to the right of z= 1.23: 1 − 0.8907 = 0.1093. 1. Use the table to find the area for the z-score. 2. The area to the left of z= 1.23 is 0.8907. 0 1.23 z
