    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.

    1. 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.
