   Question

   Hedonists turn into altruists when they have children of their own. An empirical study of this expectation requires the development of an altruism-hedonism measurement tool.

   Evaluate the following two statements on a factor analysis of a collection of items for the altruism-hedonism scale.

   I. Using the Eigenvalue greater than 1 criterion, select a set of factors based on a content criterion.

   2. After rotation of factors, interpretation of the factors usually becomes considerably more difficult than before rotation.
   
   
   1. FALSE: Pronunciation I and II are both correct.
   2. FALSE: Only pronunciation I is correct.
   3. FALSE: Only pronunciation II is correct.
   4. TRUE: Pronunciation I and II are both incorrect.
   
   

   Solution

   Explanation:

   Theorem 1: The eigenvalue criterion is a statistical criterion. It looks at statistical data without considering the content of the items or an expected number of factors.

   Theorem 2: Rotation of the factors precisely aims to make the items load more strongly on the factors, which will make the interpretation of the factors (significantly) easier.
