Changing variable reference

Postby marja » Thu Jun 16, 2016 5:53 am

Hi Guys,

For my analysis I have one variable which contains numbers between -30 and +30.
I would like to change the reference to 0 so that -30 and +30 will both get the value of 30, instead of -30 being the reference, giving +30 a value of 60. I am using both SPSS 22 and 23, does anyone know how to do this?
