Use Recode (or the Visual Binner dialog) to create the groups, and then use Split File to run the analysis separately for each group:

recode oldvar
  (lo thru 10=1) (lo thru 30=2) (lo thru 50=3) [etc...]
  into newvar.
split file by newvar.
[analysis commands]

Subject: breaking a variable's data into intervals

hi guys im a beginner and just have an spss question

if i have a variable with a bunch of numbers in it ranging from 0-200, and I
want to perform some analysis but I want to separate the variables into
intervals (for example, 0-10, 10-30, 30-50,...) and I want to run this
analysis separately for each interval.


For example, I want to see how two other variables in my data set correlate
with each other when a third variable is between 0-10, or how they correlate
when that third variable is between 10-30, and so on.

Does anyone have an idea how I can use SPSS to do this? I can think of a
long way where I choose Select -> Cases and filter the variable for each
interval and then run my analysis each time. But I'm sure there must be a
shorter way of doing this. any ideas would be great? thanks.
