Exercise 1
Use the file donations2.sav.
Construct a new variable “relicat” with categories: (1) no religion (2) catholic and
(3) protestant (reformed + rereformed). All other values have to be left out of
the analysis.
RECODE religion (1=1) (2=2) (3=3) (4=3) (SYSMIS=SYSMIS) (ELSE=SYSMIS)
INTO religioncat.
EXECUTE.
Construct a categorical variable “doncat” based on the continuous variable
“donations” with three categories such that each category contains about the
same amount of respondents. Construct a contingency table of “relicat” against
“doncat”.
RECODE donation (SYSMIS=SYSMIS) (Lowest thru 0.09=1) (0.09 thru 0.9=2)
(0.9 thru Highest=3)
(ELSE=SYSMIS) INTO doncat1.
EXECUTE.
