    The easiest way to do this is to first install the STATS PREPROCESS extension command via Extensions > Extension Hub.  Then do Transform > Preprocess Variables.  This offers several ways to standardize variables: mean-variance, scale to range, and robust scaling.  It also provides a number of ways to transform the variable distributions.

    I tried it as per the screenshots below.

    It ends up with the message "Extension command  STATS_PREPROCESS  could not be loaded. The module or a module that it requires may be missing, or there may be syntax errors in it.

    What could be the issue here?

    Run this code, which will give more information.
    Begin program python3.
    import STATS PREPROCESS
    end program.

    Three more options in addition to Jon's.

    1) Do it via syntax yourself according to the formula, utilizing AGGREGATE command as a tool to propagate values accross cases. It is easy.

    2) Use !KO_RESCALE function found on "Kirill's SPSS Macros Page", collection "Matrix - End Matrix functions".

    3) Use !KO_HRESC macro found on the page in the collection "Horizontal tools". This, however, rescales data within cases, not within variables. So you will need to transpose your data first.
