982 MEANS<br />

• The first table list produces a Group Statistics table for VARA within groups defined by<br />

each combination of values as well as the totals of VARB and VARC.<br />

• The second table list produces a Group Statistics table displaying statistics for V1 by V3<br />

by V5, V1 by V4 by V5, V2 by V3 by V5, and V2 by V4 by V5.<br />

TABLES Subcommand<br />

TABLES specifies the table list.<br />

• You can specify multiple TABLES subcommands on a single MEANS command. The slash<br />

between the subcommands is required. You can also name multiple table lists separated<br />

by slashes on one TABLES subcommand.<br />

• The dependent variable is specified first. If the dependent variable is a string variable,<br />

MEANS produces only limited statistics (COUNT, FIRST, and LAST). The control (independent)<br />

variables follow the BY keyword and can be numeric (integer or non-integer) or<br />

string.<br />

• Each use of the keyword BY in a table list adds a dimension to the table requested.<br />

Statistics are displayed for each dependent variable by each combination of values and<br />

the totals of the control variables across dimensions.<br />

• The order in which control variables are displayed is the same as the order in which they<br />

are specified on TABLES. The values of the first control variable defined for the table<br />

appear in the leftmost column of the table and change the most slowly in the definition of<br />

groups.<br />

• More than one dependent variable can be specified in a table list, and more than one control<br />

variable can be specified in each dimension of a table list.<br />

CELLS Subcommand<br />

By default, SUMMARIZE displays the means, standard deviations, and cell counts in each cell.<br />

Use CELLS to modify cell information.<br />

• If CELLS is specified without keywords, SUMMARIZE displays the default statistics.<br />

• If any keywords are specified on CELLS, only the requested information is displayed.<br />

• MEDIAN and GMEDIAN are expensive in terms of computer resources and time. Requesting<br />

these statistics (via these keywords or ALL) may slow down performance.<br />

DEFAULT Means, standard deviations, and cell counts. This is the default if CELLS is<br />

omitted.<br />

MEAN Cell means.<br />

STDDEV Cell standard deviations.<br />

COUNT Cell counts.<br />

MEDIAN Cell median.<br />

GMEDIAN Grouped median.
