In this video, I demonstrate how to run Factor Analysis and Principal Component Analysis Using SPSS. I will provide a user-friendly discussion of eigenvalue, Kaiser-Meyer-Olkin (KMO) test and Bartlett's Test of Sphericity, communalities, factor loadings, rotations (orthogonal vs oblique), and the determinant of the correlation matrix.
