Within-Cells Record Definition
When the data include factors and ROWTYPE_ is not specified, CONTENTS distinguishes between
within-cells and pooled records by enclosing the keywords for within-cells records in
parentheses.
• If the records associated with the within-cells keywords appear together for each set of
factor values, enclose the keywords together within a single set of parentheses.
• If the records associated with each within-cells keyword are grouped together across factor
values, enclose the keyword within its own parentheses.
Example
MATRIX DATA VARIABLES=F1 VAR1 TO VAR3 /FACTORS=F1 /CELLS=2
/CONTENTS=(MEAN SD N) CORR.
• MEAN, SD, and N contain within-cells information and are therefore specified within parentheses.
CORR is outside the parentheses because it identifies pooled records.
• CELLS is required because there is a factor specified and ROWTYPE_ is implicit.
Example
MATRIX DATA VARIABLES=F1 VAR1 TO VAR3 /FACTORS=F1 /CELLS=2
/CONTENTS=(MEAN SD N) CORR.
BEGIN DATA
1 5 4 3
1 3 2 1
1 9 9 9
2 4 5 6
2 6 5 4
2 9 9 9

.6 1
.7 .8 1
END DATA.
• The parentheses around the CONTENTS keywords indicate that the mean, standard deviation,
and N for value 1 of factor F1 are together, followed by the mean, standard deviation,
and N for value 2 of factor F1.
Example
MATRIX DATA VARIABLES=F1 VAR1 TO VAR3 /FACTORS=F1 /CELLS=2
/CONTENTS=(MEAN) (SD) (N) CORR.
