The Z-value is a test statistic for Z-tests that measures the difference between an observed statistic and its hypothesized population parameter in units of standard error. For example, a selection of factory molds has a mean depth of 10cm and a standard deviation of 1 cm.
The Z-Score is calculated by subtracting the mean the value you want to measure and then dividing it by the standard deviation. ((http://cran.r-project.org/doc/contrib/Verzani-SimpleR.pdf p. 46)). Using our example above, we could calculate the Z-score using the formula (8157 - 7799) / 1595 to get the result 0.2241446.
