v The four GPA variables are summarized for each value of MAJOR.
v COMPARE=VARIABLES groups the boxplots for the four GPA variables together for each value of MAJOR.
Example
EXAMINE VARIABLES=GPA1 GPA2 GPA3 GPA4 BY MAJOR /COMPARE=GROUPS.
v
COMPARE=GROUPS groups the boxplots for GPA1 for all majors together, followed by boxplots for GPA2
for all majors, and so on.
TOTAL and NOTOTAL Subcommands
TOTAL and NOTOTAL control the amount of output produced by EXAMINE when factor variables are specified.
v TOTAL is the default. By default, or when TOTAL is specified, EXAMINE produces statistics and plots for
each dependent variable overall and for each cell specified by the factor variables.
v NOTOTAL suppresses overall statistics and plots.
v TOTAL and NOTOTAL are alternatives.
v NOTOTAL is ignored when the VARIABLES subcommand does not specify factor variables.
ID Subcommand
ID assigns a variable from the active dataset to identify the cases in the output. By default the case
number is used for labeling outliers and extreme cases in boxplots.
v The identification variable can be either string or numeric. If it is numeric, value labels are used to
label cases. If no value labels exist, the values are used.
v Only one identification variable can be specified.
Example
EXAMINE VARIABLES=SALARY BY RACE BY SEX /ID=LASTNAME.
v
ID displays the value of LASTNAME for outliers and extreme cases in the boxplots.
PERCENTILES Subcommand
PERCENTILES displays the Percentiles table. If PERCENTILES is omitted, no percentiles are produced. If
PERCENTILES is specified without keywords, HAVERAGE is used with default break points of 5, 10, 25, 50, 75,
90, and 95.
v Values for break points are specified in parentheses following the subcommand. EXAMINE displays up to
six decimal places for user-specified percentile values.
v The method keywords follow the specifications for break points.
For each of the following methods of percentile calculation, w is the sum of the weights for all
nonmissing cases, p is the specified percentile divided by 100, and X i is the value of the ith case (cases
are assumed to be ranked in ascending order). For details on the specific formulas used, see the
algorithms documentation included on the installation CD.
HAVERAGE. Weighted average at X (w + 1)p . The percentile value is the weighted average of X i and X i+1 ,
where i is the integer part of (w +1)p. This is the default if PERCENTILES is specified without a keyword.
WAVERAGE. Weighted average at Xwp. The percentile value is the weighted average of X i and X (i+1) ,
where i is the integer portion of wp.
ROUND. Observation closest to wp. The percentile value is X i or X i+1 , depending upon whether i or i+
1 is "closer" to wp.
