3. Is there a dependent- and an independent- variable?

  • Yes, there are clearly identified dependent- and independent- variables, so that a regression is appropriate.
    • The data are parametric: Linear regression (other models could also be used)
    • The data are non-parametric: Non-parametric regression models are not covered here
  • No, the variables are interdependent and a test of correlation is appropriate.
