   Calculate the eigenvalue of the 6th Factor.

   
   

   Solution

   The eigenvalue of the 6th factor can be calculated as follows. The sum of the eigenvalues of 8 variables equals 8. The sum of the eigenvalues of the factors present in the table is: $2.2+1.8+1.1+.9+.8+.3+.3=7.4$. Thus, the eigenvalue of the 6th factor is: $8‐7.4= .6$.
