What is the Z-score on a TI-83 Plus family, TI-84 Plus family, or TI-Nspire™ handheld in TI-84 Plus mode? A Z-score is a value obtained when data from a symmetric distribution is standardized. The formula for determining the Z-score is: z= (x-m)/s Where x is the observation, m is the mean and s is standard deviation.

The TI-84 Plus Family of graphing calculators calculates two types of standard deviation: the standard deviation of the sample and the population standard deviation. The population standard deviation, denoted by s x, divides the calculated values by n. The sample standard deviation, denoted by Sx, uses the value n-1 as the denominator.
