STATISTICS Subcommand<br />

SUMMARIZE 1545<br />

Use STATISTICS to request a one-way analysis of variance and a test of linearity for each table<br />

list.<br />

• Statistics requested on STATISTICS are computed in addition to the statistics displayed in<br />

the Group Statistics table.<br />

• If STATISTICS is specified without keywords, SUMMARIZE computes ANOVA.<br />

• If two or more dimensions are specified, the second and subsequent dimensions are ignored<br />

in the analysis-of-variance table.<br />

ANOVA Analysis of variance. ANOVA displays a standard analysis-of-variance table<br />

and calculates eta and eta squared (displayed in the Measures of Association<br />

table). This is the default if STATISTICS is specified without keywords.<br />

LINEARITY Test of linearity. LINEARITY (alias ALL) displays additional statistics to the<br />

tables created by the ANOVA keyword—the sums of squares, degrees of<br />

freedom, and mean square associated with linear and nonlinear components,<br />

the F ratio, and the significance level for the ANOVA table and Pearson’s r<br />

and r 2 for the Measures of Association table. LINEARITY is ignored if the<br />

control variable is a string.<br />

NONE No additional statistics. This is the default if STATISTICS is omitted.<br />

Example<br />

SUMMARIZE TABLES=INCOME BY SEX BY RACE<br />

/STATISTICS=ANOVA.<br />

• SUMMARIZE produces a Group Statistics table of INCOME by RACE within SEX and computes<br />

an analysis of variance only for INCOME by SEX.
