Answer 1

A z-score is calculated by dividing the difference between a data value and the mean by the standard deviation.

The z-score formula is

`\begin{gathered} z=(x-\mu)/(\sigma) \\ Where\text{ } \\ z\text{ is the z-score} \\ x\text{ is the date value } \\ \mu\text{ is the mean.} \end{gathered}`

Hence, the answer is z-score
