How to standardize variables in SAS

In this tutorial we will cover how to standardize variables in SAS using PROC STDIZE.

Standardization

Standardization refers to subtracting the variable's mean and dividing it by the variable's standard deviation. The purpose of standardization is to transform numerical variables to a common scale, making them more easily comparable. Standardization removes the original units of measurement and centers the data around zero, with a standard deviation of one.
