Upper Endpoints. Controls treatment of upper endpoint values entered in the Va lu e
column of the grid.
 Included (<=). Cases with the value specified in the Va lue cell are included in the
banded category. For example, if you specify values of 25, 50, and 75, cases with
a value of ex
actly 25 will go in the first band, since this will include all cases
with values less than or equal to 25.
 Excluded (<). Cases with the value specified in the Valu e cell are not included in
the banded category. Instead, they are included in the next band. For example, if
you specif
y values of 25, 50, and 75, cases with a value of exactly 25 will go
in the second band rather than the first, since the first band will contain only
cases with values less than 25.
Make Cutpoints. Generates banded categories automatically for equal width
intervals, intervals with the same number of cases, or intervals based on standard
deviatio
ns. This is not available if you scanned zero cases. For more information, see
“Automatically Generating Banded Categories” on p. 124.
Make Labe ls. Generates descriptive labels for the sequential integer values of the
new, banded variable, based on the values in the grid and the specified treatment of
upper en
dpoints (included or excluded).
Reverse
scale.
By default, values of the new, banded variable are ascending sequential
integers from 1 to n. Reversing the scale makes the values descending sequential
integers from n to 1.
Copy Bands. You can copy the banding specifications from another variable to the
curren
tly selected variable or from the selected variable to multiple other variables.
For more information, see “Copying Banded Categories” on p. 127.
