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 at least one numeric variable.

Method

1. Select the numeric variable in the Data Sources tree.
2. Click + > Numeric Transformations > Square-Root. This creates a numeric variable.

3. If you select the newly created variable in the Data Sources tree and, from Properties , click Data > Attributes > Code to see the R code used to create the transformation.
   

   OPTIONAL: If a different power transformation is required, the user can modify the R code used to compute the transformation. See the instructions in the commented lines of code (in green).

4. To check the data, select the original numeric and the square root variables in the Data Sources tree and go to Table > Raw Data > Variable(s). This will tabulate the raw data for each respondent as seen above.
