How to createtwo groups using median split?

[Mbaye Fall Diallo]

Dear all,
I intend to use median split samples in order to perform multiple group analysis later. I have two variables (experience and frequence) measured by with 4- points scales. I want to have two groups (high and low familiarity). Do you have some syntaxe that can do this? Your comments and help will be appreciated.

Thanks in advance.

Hi Mbaye,

 

Can you think of computing of a composite variable from the exisiting two? If you can, you can use something as below:

 

 

 

DATASET ACTIVATE DataSet0.

 

*** do compute the composite variable eg. adding the two ( you know better how they relate!)

compute Var3 = var1 + var2.
execute.  

 

*** determine the median value
FREQUENCIES VARIABLES=Var3
  /NTILES=2
  /ORDER=ANALYSIS.

 

*** once you know the split spoint, try recoding into two groups like this

 

IF  (Slno <=  11) GroupVar=Slno <= 11.
EXECUTE.

RECODE Slno (1 thru 11=1) (ELSE=2) INTO groupVar.
EXECUTE.

 

HTH,
