   Question

   In an oblique rotation spss gives a structure and a pattern matrix as output. Consider the following statements with respect to these matrices:

   1. The correlations between the factors are zero in the structure matrix.
   2. The numbers in the pattern matrix are the unique correlations between a factor and an item.
   
   
   1. FALSE: Statement 1 is correct and statement 2 is incorrect.
   2. TRUE: Statement 2 is correct and statement 1 is incorrect.
   3. FALSE: Statement 1 and 2 are both correct.
   4. FALSE: Statement 1 and 2 are both incorrect.
   
   

   Solution

   Statement 1 is incorrect. The structure matrix contains the correlations between the items and the factors; in an oblique rotation the correlation between the factors is not necessarily zero. Statement 2 is correct: the pattern matrix contains the correlations between the factor and the items corrected for the correlation between factors.
