How to Create Square-Root Variable(s)

This article describes how to create a new variable(s) by applying the square root transformation to the selected variable(s).

Requirements

• Data loaded into a Displayr document must contain Numeric variables.

Method

1. Select the variable in the Data Sources tree.
2. Click + > Numeric Transformations > Square-Root. This creates a numeric R variable.
3. If you select the newly created variable in the Data Sources tree and under Data > R Code > Edit Code, you will see the R code used to create the transformation.
   
4. To check the data, select both variables in the Data Sources tree and go to Anything > Table > Raw Data > Variable(s). This will tabulate the raw data for each respondent as seen above.
5. OPTIONAL: If a different power transformation is required, the user can modify the R code used to compute the transformation.
