I want to re-enter the data after doing varimax rotation in exploratory factor analysis. As the number of variables have reduced from 12 to 4, how to plot it in SPSS.
You will need to create new variables for the four factors noted by EFA. In SPSS this is easily accomplished by Transform/Compute Variable which will allow you to mathematically join item responses for each factor as needed.
An even better method is to save the regression scores when you carry out the final EFA. I would recommend using a principal component analysis to verify your scales and saving the regression scores with this process.
