Split population from non-binary variable

francy2288
Hi guys, I'm pretty new on SPSS. I have a population with classic age
variable and a non-binary ordinal variable (let's say values from 1 to 10,
or from A to L). I would like to create only 2 sub-groups, A and B, to
compare the ages. For example, how can I compare ages between group A
(values 1-3-4) and group B (2-5-6-7-8-9-10)?
Thanks for your time.

DISCLAIMER:  If the two sub-groups cannot be specified in advance (i.e.,
before seeing the data), sub-group analysis is suspect, because it
capitalizes on the play of chance in a particular sample.  

Having said that, this should do what you ask.

RECODE OrdinalVar (1 3 4 = 1) (ELSE=2) INTO Group.
FORMATS Group(F1).
VALUE LABELS Group
 1 "A (1-3-4)"
 2 "B (2-5-6-7-8-9-10)"
.
T-TEST GROUPS=Group(1 2)
 /MISSING=ANALYSIS
 /VARIABLES=Age
 /CRITERIA=CIN(.95).

It's ordinal, but you don't want 2 in the same group as 1, 3 and 4?

Indeed, unless OP has a truly twisted definition of ORDINAL variable!

Re: Split population from non-binary variable

In reply to this post by Bruce Weaver
Just a note: The recode assumes there are no missing values in the OrdinalVar.
If there are missing OrdinalVar, they will need to be handled slightly differently.
See the FM for more.
