Answer

Depending on what the distribution represent z score is calculated as shown below:-

Z- score of a population

$z = \frac{x - μ}{σ}$

Z- score of a sample

$z = \frac{x - μ}{s}$

Example:-

Given a sample of 50 individuals with a mean of 50 and standard deviation of 10, a z score of 60 will be calculated as:-

$z = \frac{x - μ}{s}$

$z = \frac{60 - 50}{10} = \frac{10}{10} = 1$
