Likert scale in correlation analysis

Hi all. I am working on my master thesis and are struggling with my correlation analysis.

My plan for the statistics from my survey are:

  1. Item analysis
  2. PCA and factor analysis
  3. Correlation analysis
  4. Multiple regression
  5. Cluster analysis.


In my assumptions in correlation analysis I have problems with the fitting of the likert scale data to find linearity among other things. Is it better to use the factor scores from factor analysis of my independent variables or should I use my likert scale ratings, which is not continuous?


My dependant variable is also a likert scale.


Best regards
