# z = \frac{x-\mu}{\sigma} #

Explanation:

The formula for converting raw score (x) into standardized score (z) is the following:

# z = \frac{x-\mu}{\sigma} #

Here #\mu# is the population mean and #\sigma# is the population standard deviation. If these are unavailable, then corresponding sample mean and sample standard deviation can also be used as an approximation.
