Run a Principal Axis Factor Analysis (PFA), with default
settings for the “Eigenvalue greater than 1” option. Just use the
default rotation of ‘orthogonal’ for now.
a.)Considering at least two rules-of-thumb discussed, what do
the eigenvalues (you will need to “eyeball” these values from the
plots) and scree plot suggest about the number of factors
underlying the variables? Explain your answer (10 points)
b.)Interpret and explain the communality variables (Hint:
remember communality = 1 – uniqueness)? In what way do...
