Standardizing within variable means scaling each column of the raw data so that it has a mean of 0 and a standard deviation of 1. This article describes how to go from the data below:

For each column/variable in the data, centering within variable will subtract the mean for the column from each entry in the column to yield the following:

This creates for each selected containing the transformed data after centering within each variable.

## Requirements

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

## Method

This

creates for each selected containing the transformed data after centering within the variable. To standardize a variable:- Select the variable or variable sets in the
**Data Sets**tree. - Still in the
**Data Sets**tree, either hover over any variable in your**Data Sets**tree**> Plus (+) > Insert Variable(s) > Ready-Made New Variable(s) >****Scale Variable(s) > Center Within Variable****Anything > Data > Variables > New > Ready-Made New Variable(s) >****Scale Variable(s) > Center 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 standardize, click
**OK**. - A new numeric variable is created.
**Centering data**means that the average of a variable is subtracted from the**data**.
