Deterministic and stochastic relationship
Covariance, (Pearson’s) correlation
When not to use correlation and linear regression
In previous chapters we looked at the relationships between low measurement level variables. Below, we’ll explore high measurement level variables. Please revise high measurement level.
Questions to consider when exploring the potential relationship between variables:
Is there a relationship?
How strong is it?
Which way does it point?
As we’ll see, for high measurement level variables we have to ask some other questions as well.
