When to use it

Use this tool while preparing an analysis-ready dataset or correcting a known data issue.
Use it only when the selected variables and study design match the method's requirements.

02

How to use it

  1. Open the tool from the Quantly Tools panel.
  2. Confirm the active dataset and analysis session.
  3. Set New Variable Name (Required): Name of the new variable to create.
  4. Set Expression (Required): Arithmetic expression involving column names (e.g., 'ColA + ColB / 2').
  5. Set Save as New Dataset (Optional): Create a new dataset with the new variable.

How to interpret results

Confirm the affected rows and columns before saving. Review the output dataset and warning counts; transformations change data rather than proving a statistical conclusion.
