Steps to Follow When Conducting EFA
Exploratory factor analysis is meant to be exploratory
in nature, and thus it is not desirable to prescribe a rigid formula
or process for executing an EFA. The steps below are meant to be a

that will guide the discussion through the rest of the book:
-
Data cleaning
-
Deciding on an extraction method to use
-
Deciding how many factors to retain
-
Deciding on a method of rotation (if desired)
-
Interpreting results (return to #3 if a solution is not ideal)
-
