By default, SPSS selects the MEAN, STDDEV, MINIMUM, and MAXIMUM options automatically.
The /SAVE subcommand computes Z-statistics and writes them to new variables.
Missing
By default, SPSS will exclude observations with a user missing value for any variable. Add the /MISSING=LISTWISE NOINCLUDE subcommand to explicitly allow this behavior, or add /MISSING=INCLUDE subcommand to disable it, or add the /MISSING=VARIABLE NOINCLUDE subcommand to exclude user missing values from only the corresponding variable's statistics.
Data Model
The FREQUENCIES command causes all pending transformations to execute, and reads the active dataset.
