    Question

    In the study The Boundless Youth, a questionnaire was administered to a random sample of over 500 young people between the ages of 12 and 25. The following eight personality characteristics were operationalized: narcissism, materialism, social involvement, hedonism, self-centeredness, altruism, self-reliance, and last but not least, crazy-in-your-head.

    Over the test scores, the researchers plan to conduct an exploratory higher-order factor analysis (PAF) with orthogonal rotation. The researchers request a consultation with an expert in factor analysis. They submit the following two statements to the expert.

    I. The Eigenvalue of a factor is the percentage of variance in test scores explained by that factor. II. No correlation between factors (axes) is possible after orthogonal rotation.


    1. FALSE: I and II are correct
    2. FALSE: Only I is correct
    3. TRUE: Only II is correct
    4. FALSE: I and II are incorrect
