Which method is used for oblique rotation?

• A. Discriminant analysis
• B. Difference contrast
• C. DFBeta
• D. Direct oblimin

Answer: (D)

In factor analysis, after extracting factors you rotate them to achieve a simpler, more interpretable structure. Rotation can be orthogonal, keeping factors uncorrelated, or oblique, allowing factors to correlate. Oblique rotations are used when you expect the underlying factors to be related rather than completely independent. Direct Oblimin is a specific oblique rotation method. It rotates the factor solution while permitting correlations among factors, which is why it’s chosen when you suspect related constructs. In contrast, the other options aren’t rotation methods: discriminant analysis is a classification technique, difference contrast is a coding scheme for contrast analysis, and DFBeta is a regression diagnostic statistic.
