Standard Deviations. The Standard Deviation is a measure of how spread out numbers are (read that page for details on how to calculate it). When we calculate the standard deviation we find that (generally): 68% of values are within. 1 standard deviation of the mean. 95% of values are within.ou can calculate the rest of the z-scores yourself! Here is the formula for z-score that we have been using: 1  z is the z-score (Standard Score). 2  x is the value to be standardized. 3  Î¼ is the mean.
