DESCRIPTIVES VARIABLES = mpg weight /SAVE. You can confirm that the variables were standardized properly with the descriptives command.

**How to standardize mpg and weight in SPSS?**

You can use the descriptives command with the save subcommand to make standardized variables. The command below makes standardized values for mpg and weight (called zmpg and zweight ). The save subcommand tells SPSS to make and save the z-scores of the variables listed on the descriptives command. SPSS saves the new variable (s)
