Advice for using SPSS with nominal vs. ordinal

[Omar Farook]

Dear Experts,
  What type of analysis in SPSS we have to use if we want to detect the relationship between two variables nominal vs. ordinal?
  Nominal var, with 3 levels (independent)
  Ordinal var, dependent with 5 levels
  Sample size 40
  Thanks.

Check to see if the Kruskal-Wallis one-way analysis of variance with ranks
is appropriate for your research design. If so, you can find it in the menu
system under Analyze/non-parametric tests/k independent samples.

Hi All

I have a number of omnibus macros that do many calculations for
varaibles in the file. In some cases my variable names are improper and
SPSS writes them to the end of the file and they can be seen there in
variable view. What I would like is to receive a warning in the output
that this has occurred.

Does anyone know if this is currently possible?

If not, could Kyle or one of the SPSS people please consider this for an
enhancement

Warm regards/gary

Hi Gary,

this is possible in SPSS. If you use SPSS syntax an macros it is more complicated than using the new Python programmability extension. With Python it is very easy to access the data dictionary and perform computations or analysis steps based on the conditions found in the data dictionary at a certain time.

You can find more information in Raynald Levesque's data management handbook. Please have a look at chapter 14 Working with Variable Dictionary Information on p. 254 of the 4th edition of that book. You download this book for free from the SPSS site by clicking on http://www.spss.com/spss/data_management_book.htm.

Best regards

Georg Maubach

It sounds like you want something like
Option Explicit
which is available in SaxBasic.  That applies only to variables in the SaxBasic code, though.

While there is no direct way to do this in SPSS, it would be very easy to use two tiny Python programs in your job stream to report new variables.

When you want to start counting, do
begin program.
import spss
numvars = spss.GetVariableCount()
end program.

When you want to check for new ones, run
begin program.
import spss
newnumvars = spss.GetVariableCount()
if newnumvars > numvars:
   print "*** New variables created: ",
   "\n".join([spss.GetVariableName(v-1) for v in range(numvars, newnumvars)])
end program.

You could put each of these little blocks of code in a file and invoke them with an INSERT command (not an INCLUDE command).

This approach assumes that you are not deleting any variables or changing the order.  It would be only a small amount of additional work to generalize this code to cover that case.

Of course this requires SPSS 14 or later and the Python plugin from SPSS Developer Central (www.spss.com/devcentral)

HTH,

Just one small correction to the code Jon provided: the line before the last
should say

print "*** New variables created: ", "\n".join([spss.GetVariableName(v) for
v in range(numvars, newnumvars)])

Instead of

print "*** New variables created: ", "\n".join([spss.GetVariableName(v-1)
for v in range(numvars, newnumvars)])

Luca

Good catch.  Variables are numbered starting with 0, and range(a,b) returns values a, a+1,... a+k where a+k < b.  The upper limit is excluded.
