## Introduction

Sometimes it is necessary to transform variable(s) so that the mean of the data is 0 and the standard deviation is 1. Such a variable is *normalized* or *standardized*. There are two approaches to standardizing: within each *case* *or respondent* and within each* variable. *Both can be done with QScripts in Q's Online Library.

## Method 1: Standardizing Within Case

To create new variables where the values across the selected variables are standardized data *within respondent* do the following. The new standardized data will have an average of 0 for each respondent, and will optionally have a standard deviation of 1 for each respondent across the selected variables.

- Go to the
**Variables and Questions**tab. - Select the variables you want to standardize.
- Go to
**Automate > Browse Online Library > Create New Variables > Scale Variable(s) > Standardize Within Case**

## Method 2: Standardizing Within Variables

To create new variables where the values are standardized *within each variable *do the following. The new standardized data will have an average of 0 for each variable, and will optionally have a standard deviation of 1 for each variable.

- Go to the
**Variables and Questions**tab. - Select the variables you want to standardize.
- Go to
**Automate > Browse Online Library > Create New Variables > Scale Variable(s) > Standardize Within Variable**
