This article describes how to create a new variable(s) that is standardized and will have an average of 0 for each respondent, will optionally have a standard deviation of 1 for each respondent. Please consider the data below:

For each column/variable in the data, this QScript will subtract the mean of the column from each entry and then divide by the standard deviation of the column to yield the following

## Requirements

- A Displayr document that contains
**Numeric - Multi**or**Binary- Multi**variable sets.

## Method

To use this transformation:

- Select one or more
**Numeric - Multi**or**Binary- Multi**variable sets in the**Data Sets**tree. - Still in the
**Data Sets**tree, hover where you want to insert the new variable, then click the**+**button to select**Ready-Made new Variables > Scale Variable(s) >****Standardize Within Variable**. - 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 R question containing the standardized data
*within the variable*is created.
