Grade 11 Collecting and Interpreting Data CCSS: HSS-ID.A.4

Which of the following is the formula for calculating the z-score of a value of

$x$ , where

$x$ is a value (or raw score) from a set of normally distributed data? Let

$mu$ be the population mean and

$sigma$ be the population standard deviation of this data.

$z = x/sigma$
$z = x - mu/sigma$
$z = (x - mu)/sigma$
$z = sqrt((x-mu)/sigma)$
