Reverse scaling for continuous variables

[Susan Seibold-Simpson]

Hi all-
I'm new to this list and haven't figured out how to work the archives yet, so I apologize if this has been previously discussed.

I'm looking for assistance on how to reverse code continuous variables with many values.  For example, median income levels from the Bureau of Census is one of the variables I need to reserve scale.  I know how to reverse code categorical variables, but haven't figured out how to do variables with a large amount of variables.

Thanks for your help.

Hi Susan,

If you multiply your income variable by -1, the absolue value of, e.g., a
correlation coefficient would stay the same but the direction would flip.
Would that give you what you're looking for?

COMPUTE incomeRev = income*-1 .

Best,

--Justin
