SPSS® 12.0 Command Syntax Reference

400 CTABLES
• The TITLE specification on the TITLE subcommand uses the standard SPSS convention to
break a single string across input lines.
• The CAPTION specification uses the )DATE, )TIME, and )TABLE keywords to print the date,
time, and a description of the table structure.
Significance Testing
Custom Tables can perform the chi-square test of independence and pairwise comparisons of
column proportions for tables that contain at least one category variable in both the rows and
the columns, and pairwise comparisons of column means for tables that contain at least one
summary variable in the rows and one category variable in the columns.
Chi-Square Tests: SIGTEST Subcommand
/SIGTEST TYPE= CHISQUARE ALPHA= {0.05 }
{significance level}
The SIGTEST subcommand has the following specifications:
TYPE The type of significance test. The specification is required. The only current choice
is CHISQUARE.
ALPHA The significance level for the test. The specification must be greater than 0 and less
than 1. The default is 0.05.
