automated recode data to 3 tertiles

Postby NeutrophilClair » Fri Feb 24, 2017 11:43 pm

I'm looking for a way to split data from scale to 3 ordinal categories. I have interrogated where the tertiles sit using frequency descriptives but with 20 data points I would like to expedite the process and elimenate any transcription errors by automating the split. Recode into different variables has the potential to contain a shortcut but I can't find it. Does anyone know how to make this happen? Many thanks

Hi,
You can use the rank command.
rank VARIABLES=MyScores /ntiles(3) into MyTertiles.
