Quizplus · Accepted Answer

All of the options (A, B, C, D) are valid strategies for determining the number of factors to retain in a factor analysis. Examining latent roots (eigenvalues), plotting them (scree plot), and assessing the amount of (co)variability explained are common practices in factor analysis to ensure a meaningful and interpretable solution.
