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, also known as standard score, is a measurement used in statistics. It is the measurement of the number of standard deviations a specific number is above or below a mean. The formula to calculate z-score is. z = (x - Î¼) / Ï. where. 1  z is the z-score, 2  x is the value to be standardized,3  Î¼ is the mean of the given set of data, 4  Ï is the standard deviation of the given set of data.t is the measurement of the number of standard deviations a specific number is above or below a mean.
