Slide 12.12: Data structure and selection of appropriate variables in correlation submenu in analysis menu of SPSS
Step 3: Click OK to get the following output.
In the similar fashion, by changing the variables
in Step 2, one can have different combinations
of partial correlation coefficients among the
variables. Given below are the different partial
correlation coefficients of dependent variable
Y
with other variables as worked out following the
above process (Table
12.5
).
