This article describes how to create a new variable(s) that is standardized and will have an average of 0 for each respondent, and that will optionally have a standard deviation of 1 for each respondent. The *Sample Standard Deviation* is used in this calculation. Please consider the data below, on the left is the raw data of a scale question *Strongly agree* to *Strongly disagree*. On the right is the same raw data but standardized.

## Requirements

- A Displayr document that contains one or more
**Nominal - Multi**,**Ordinal - Multi**,**Numeric - Multi**,**Numeric - Grid**,**Nominal**,**Ordinal**or**Numeric**variable sets.

Please note these steps require a **Displayr **license.

## Method

To use this transformation:

- Select one or more
**Nominal - Multi**,**Ordinal - Multi**,**Numeric - Multi**,**Numeric - Grid**,**Nominal**,**Ordinal**or**Numeric**variable sets in the**Data Sources**tree. - Still in the
**Data Sources**tree, either hover over any variable in your**Data Sources**tree**> Plus (+) > Insert Variable(s) > Ready-Made New Variable(s) >****Scale Variable(s) >****Standardize Within Case**or else from the toolbar menu, select the icon**> Data > Variables > New > Ready-Made New Variable(s) >****Scale Variable(s) >****Standardize Within Case**. - OPTIONAL: If your document contains more than one data file you will be prompted to select the data file. Click
**OK**. - Next, you will be asked to select the variable sets you want to transform, click
**OK**. - For each selected variable set, a new variable set containing the standardized data
*within the respondent*is created.
