522 EXAMINE<br />

Example<br />

EXAMINE VARIABLES=GPA1 GPA2 GPA3 GPA4 BY MAJOR /COMPARE=VARIABLES.<br />

• The four GPA variables are summarized for each value of MAJOR.<br />

• COMPARE=VARIABLES groups the boxplots for the four GPA variables together for each<br />

value of MAJOR.<br />

Example<br />

EXAMINE VARIABLES=GPA1 GPA2 GPA3 GPA4 BY MAJOR /COMPARE=GROUPS.<br />

• COMPARE=GROUPS groups the boxplots for GPA1 for all majors together, followed by<br />

boxplots for GPA2 for all majors, and so on.<br />

TOTAL and NOTOTAL Subcommands<br />

TOTAL and NOTOTAL control the amount of output produced by EXAMINE when factor variables<br />

are specified.<br />

• TOTAL is the default. By default, or when TOTAL is specified, EXAMINE produces statistics<br />

and plots for each dependent variable overall and for each cell specified by the<br />

factor variables.<br />

• NOTOTAL suppresses overall statistics and plots.<br />

• TOTAL and NOTOTAL are alternatives.<br />

• NOTOTAL is ignored when the VARIABLES subcommand does not specify factor variables.<br />

ID Subcommand<br />

ID assigns a variable from the working data file to identify the cases in the output. By default<br />

the case number is used for labeling outliers and extreme cases in boxplots.<br />

• The identification variable can be either string or numeric. If it is numeric, value labels<br />

are used to label cases. If no value labels exist, the values are used.<br />

• Only one identification variable can be specified.<br />

Example<br />

EXAMINE VARIABLES=SALARY BY RACE BY SEX /ID=LASTNAME.<br />

• ID displays the value of LASTNAME for outliers and extreme cases in the boxplots.<br />

PERCENTILES Subcommand<br />

PERCENTILES displays the Percentiles table. If PERCENTILES is omitted, no percentiles are<br />

produced. If PERCENTILES is specified without keywords, HAVERAGE is used with default<br />

break points of 5, 10, 25, 50, 75, 90, and 95.<br />

• Values for break points are specified in parentheses following the subcommand. EXAMINE<br />

displays up to six decimal places for user-specified percentile values.
